Thanks!
I know why it don't work, WzAG.dll!!!
But I won't modify the wzag.dll.
bro,U konw modify or U know where to teach modify?

I just finished optimizing the 3D camera for performance and display.
25 FPS is optimal for Mu Online.
I also added ATI and NVidia support + CPU Info.

In my opinion, the result is sufficient.
The most FPS limits the rendering of objects on maps.

Just adjust the edges of the rendering of the objects and you can start testing.

After that I will share with you.

The problem is in the rendering system. Making a good shader for rendering and using correctly the buffer system of the graphic driver will improve the performance a lot. Even adding fog to avoid the objects pop in and pop out magically, rendering the correct side of the objects face culling (in your video when you move the camera, the wooden gates looks transparent).

If you want to improve the rendering system, i think you should rebuild the complete system using higher version of OpenGL and making good GLSL files.

I already figured it out, there is a rendering error in the game server.

It's actually not a "rendering error" of the game server. It's by design, because the server optimized that for the normal camera frustum. The original game is not designed for a 3D Camera with changing perspectives.

Of course, you can increase this frustum on the server side, but that also has downsides, which should be kept in mind, for example:
- It not only increases the load on the client side (I saw you worked on that), but also on the server. It needs to notify more players about changes, so it increases the network traffic a lot, when there are more objects (players, monsters) on the map.
- Also, it might be strange from a sound perspective. Afaik, the client plays sound effects of all objects it currently knows at full volume. With an increased frustum on the server, the client plays sounds of objects far away, which it might not see.

You still don't understand what OpenGL is.

I would like to explain something else.

OpenGL is the perfect tool. You can use, for example, EGL or another rewritten version, but if you do not remove the errors in the coding, you will not have a better rendering.

What you write can be done in OpenGL using six lines.

The truth is that it is a mistake.

- This is an original function with a condition for the distance between the object and the player.

BOOL gObjCheckViewport(int aIndex, int x, int y)
{
    if(OBJMAX_RANGE(aIndex) == 0)
    {
        return false;
    }

    LPOBJ lpObj = &gObj[aIndex];

    if(x < lpObj->X - 15  || x > lpObj->X + 15 || y < lpObj->Y - 15 || y > lpObj->Y + 15)
    {
        return false;
    }

    int j = 3;

    for(int i = 0; i < MAX_ARRAY_FRUSTRUM; j = i, i++)
    {
        int frustrum = (lpObj->FrustrumX[i]- x) * (lpObj->FrustrumY[j]-y) - (lpObj->FrustrumX[j]-x) * (lpObj->FrustrumY[i]-y);
        if(frustrum < 0)
        {
            return false;
        }
    }
    return true;
} 

- This is a condition modified by me

BOOL gObjCheckViewport(int aIndex, int x, int y)
{
    LPOBJ lpObj = &gObj[aIndex];

    int distance = 20;
    if(x < lpObj->X - distance || x > lpObj->X + distance || y < lpObj->Y - distance || y > lpObj->Y + distance)
    {
        return false;
    }

    int j = 3;

    for(int i = 0; i < 4; j = i, i++)
    {
        int frustrum = (lpObj->FrustrumX[i]- lpObj->X) * (lpObj->FrustrumY[j]- lpObj->Y) - (lpObj->FrustrumX[j]- lpObj->X) * (lpObj->FrustrumY[i]- lpObj->Y);
        if(frustrum < 0)
        {
            return false;
        }
    }
    return true;
} 

The change is minimal and you don't need to make the difference of two points big.

I know its easy to add fog effect and correct the face culling of the objects.
You misunderstood me. I said that you need to IMPROVE the actual code with OpenGL, not changing OpenGL itself. I give an example of GLSL (OpenGL Shading Language) that is used in newer versions of OGL. What i meant when i said 'If you want to improve the rendering system, i think you should rebuild the complete system' is the same as what you're saying about correcting the code.
Even i said UPGRADE the OpenGL Version, because by default its using OGL 1.1 (defined by Windows library) and not the latest OGL version (defined by Graphics Card's Drivers) and that takes down a lot of performance.

Understood, but did you also modify the frustum? Because otherwise, you'll not see very far if you rotate the camera to specific directions, e.g. to the opposite of the default direction (downwards).

please shared camera 3D

[leorond]

Today I will give you 3D camera source codes. When I get home from work.

[leorond]

As promised, I will share with you my work on the 3D camera.

I want to inform you that I am still working on the 3D camera.

Unfinished or in preparation...
1. Damage listing function
2. Complete saving of settings in windows registry
- drawing objects on the map
3. FPS, CPU usage for maximum performance
4. Reworked feature for monster sounds

Here I will add instructions for the 3D camera, which is controlled by the arrow keys and the keys PgUp, PgOn, END

1. defining all variables
- In the ZzzOpenglUtil.cpp file, add the definitions

//////////////////////////////////////////////////////////////////////////
//  Global Variable.
//////////////////////////////////////////////////////////////////////////
int     OpenglWindowX;     
int     OpenglWindowY;     
int     OpenglWindowWidth; 
int     OpenglWindowHeight;
bool    CameraTopViewEnable = false;
float   CameraViewNear      = 20.f;
float   CameraViewFar       = 2000.f;
float   CameraFOV           = 55.f;
// ---- 3D camera ----
float    CameraZoom            = 0.f;
float    AngleX3D            = 0.f;
float    AngleY3D            = 0.f;
float    AngleRL                = 0.f;
// -------------------
vec3_t  CameraPosition;
vec3_t  CameraAngle;
float   CameraMatrix[3][4];
vec3_t  MousePosition;
vec3_t  MouseTarget;
float   g_fCameraCustomDistance = 0.f;
bool    FogEnable   = false;
GLfloat FogDensity  = 0.0004f;
GLfloat FogColor[4] = {30/256.f,20/256.f,10/256.f,}; 

- In the Winmain.h file, add the definition

extern char m_ID[];
extern char m_Version[];
extern int  m_SoundOnOff;
extern int  m_MusicOnOff;
// ---- 3D camera ----
extern int    m_CameraOnOff;
// -------------------
extern int  m_Resolution;
extern int m_nColorDepth; 

- In the Winmain.cpp file, find the BOOL OpenInitFile() function and add a definition above this function

char m_ID[11];
char m_Version[11];
char m_ExeVersion[11];
int  m_SoundOnOff;
int  m_MusicOnOff;
// ---- 3D camera ----
int    m_CameraOnOff;
// -------------------
int  m_Resolution;
int    m_nColorDepth;
int    g_iRenderTextType = 0;

#ifdef LJH_ADD_SUPPORTING_MULTI_LANGUAGE
// ´Ů±ąľî Áöżř ·±ĂÄżˇĽ­ Ľ±ĹĂµČ ľđľî
char g_aszMLSelection[MAX_LANGUAGE_NAME_LENGTH] = {'\0'};
string g_strSelectedML = "";
#endif //LJH_ADD_SUPPORTING_MULTI_LANGUAGE

//int ĆÄŔĎ ŔĐ´Â ÇÔĽö
BOOL OpenInitFile()
{ 

2. Creating a 3D camera launcher using windows registry save
- Go to the BOOL OpenInitFile() function in the Winmain.cpp file and supply the following condition to validate and possibly write to the windows registry

    m_ID[0] = '\0';
    m_SoundOnOff = 1;
    m_MusicOnOff = 1;
// ---- 3D camera ----
    m_CameraOnOff = 1;
// -------------------
    m_Resolution = 0;
    m_nColorDepth = 0; 

        dwSize = 11;
        if ( RegQueryValueEx (hKey, "ID", 0, NULL, (LPBYTE)m_ID, & dwSize) != ERROR_SUCCESS)
        {
        }
        dwSize = sizeof ( int);
        if ( RegQueryValueEx (hKey, "SoundOnOff", 0, NULL, (LPBYTE) & m_SoundOnOff, &dwSize) != ERROR_SUCCESS)
        {
            m_SoundOnOff = true;
        }
        dwSize = sizeof ( int);
        if ( RegQueryValueEx (hKey, "MusicOnOff", 0, NULL, (LPBYTE) & m_MusicOnOff, &dwSize) != ERROR_SUCCESS)
        {
            m_MusicOnOff = false;
        }
// ---- 3D camera ----
        dwSize = sizeof ( int);
        if ( RegQueryValueEx (hKey, "3DCameraOnOff", 0, NULL, (LPBYTE) & m_CameraOnOff, &dwSize) != ERROR_SUCCESS)
        {
            m_CameraOnOff = false;
        }
// -------------------
        dwSize = sizeof ( int);
        if ( RegQueryValueEx (hKey, "Resolution", 0, NULL, (LPBYTE) & m_Resolution, &dwSize) != ERROR_SUCCESS)
        {
            m_Resolution = 1;
        } 

- Now go to the NewUIOptionWindow.h file and define a new public function

void SetCameraOnOff(); 

- Then create a new function in the NewUIOptionWindow.cpp file
- This function checks if a setting for the camera exists in the registry and has permission to change the value of that setting

void SEASON3B::CNewUIOptionWindow::SetCameraOnOff()
{

    HKEY hKey;
    DWORD dwDisp;
    DWORD dwSize;
    dwSize = sizeof ( int);
    if ( ERROR_SUCCESS == RegCreateKeyEx(HKEY_CURRENT_USER, "SOFTWARE\\Webzen\\Mu\\Config", 0, NULL, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, & hKey, &dwDisp))
    {
        m_CameraOnOff = !m_CameraOnOff;
        RegSetValueEx(hKey, "3DCameraOnOff", 0, NULL, (LPBYTE) & m_CameraOnOff, dwSize);
    }
    RegCloseKey( hKey);
} 

- Go to the Render Buttons() function in the NewUIOption Window.cpp file and create a checkbox for the 3D camera
- My settings save is next to the Effects render settings name

    // 3D Camera checkbox
    if(m_CameraOnOff)
    {
        RenderImage(IMAGE_OPTION_BTN_CHECK, m_Pos.x+150, m_Pos.y+149, 15, 15, 0, 0);
    }
    else
    {
        RenderImage(IMAGE_OPTION_BTN_CHECK, m_Pos.x+150, m_Pos.y+149, 15, 15, 0, 15.f);
    } 

- Go to the RenderContents() function in the NewUIOption Window.cpp file and create a dot before the description and the settings description itself for the 3D camera

void SEASON3B::CNewUIOptionWindow::RenderContents()
{
    float x, y;
    x = m_Pos.x + 20.f;
    y = m_Pos.y + 46.f;
    RenderImage(IMAGE_OPTION_POINT, x, y, 10.f, 10.f);
    y += 22.f;
    RenderImage(IMAGE_OPTION_POINT, x, y, 10.f, 10.f);
    y += 22.f;
    RenderImage(IMAGE_OPTION_POINT, x, y, 10.f, 10.f);
    y += 40.f;
    RenderImage(IMAGE_OPTION_POINT, x, y, 10.f, 10.f);
    y += 22.f;
    RenderImage(IMAGE_OPTION_POINT, x, y, 10.f, 10.f);
    // 3D Camera
    RenderImage(IMAGE_OPTION_POINT, x+60, y, 10.f, 10.f);
    
    g_pRenderText->SetFont(g_hFont);
    g_pRenderText->SetTextColor(255, 255, 255, 255);
    g_pRenderText->SetBgColor(0);
    // 386 "ŔÚµż °ř°Ý"
    g_pRenderText->RenderText(m_Pos.x+40, m_Pos.y+48, GlobalText[386]);
    // 387 "±Ó¸» ľË¸˛Ŕ˝"
    g_pRenderText->RenderText(m_Pos.x+40, m_Pos.y+70, GlobalText[387]);
    // 389 "şĽ·ýÁ¶Ŕý"
    g_pRenderText->RenderText(m_Pos.x+40, m_Pos.y+92, GlobalText[389]);
    // 919 "˝˝¶óŔĚµĺ µµżň¸»"
    g_pRenderText->RenderText(m_Pos.x+40, m_Pos.y+132, GlobalText[919]);
    // 1840 "+Čż°úÁ¦ÇŃ"
    g_pRenderText->RenderText(m_Pos.x+40, m_Pos.y+154, "+Effect");
    // 3D Camera
    g_pRenderText->RenderText(m_Pos.x+100, m_Pos.y+154, "3D Camera");
} 

- Now go to the UpdateMouseEvent() function in the NewUIOption Window.cpp file and create an action when the 3D camera checkbox is checked

    if(SEASON3B::IsPress(VK_LBUTTON) && CheckMouseIn(m_Pos.x+150, m_Pos.y+127, 15, 15))
    {
        m_bSlideHelp = !m_bSlideHelp;
    }
    // 3D Camera
    if(SEASON3B::IsPress(VK_LBUTTON) && CheckMouseIn(m_Pos.x+150, m_Pos.y+149, 15, 15))
    {
        SetCameraOnOff();
    }
    
    if(CheckMouseIn(m_Pos.x+33-8, m_Pos.y+104, 124+8, 16)) 

Now we have our startup setup ready and we can get down to the 3D camera itself

3. Creating a 3D camera control
- This control setting is contained in the ZzzScene.cpp file and can be customized to your liking.
I chose keyboard control for the player's convenience.

- Go to the ZzzScene.cpp file in the MoveMainCamera() function and add the settings for the 3D camera.
- Edit the first condition of the function as follows.

    if (
#ifdef PJH_NEW_SERVER_SELECT_MAP
        World == WD_73NEW_LOGIN_SCENE
#else
        World == WD_77NEW_LOGIN_SCENE
#endif //PJH_NEW_SERVER_SELECT_MAP
        && CCameraMove::GetInstancePtr()->IsTourMode())
#ifdef PJH_NEW_SERVER_SELECT_MAP
        CameraFOV = 65.0f;
#else //PJH_NEW_SERVER_SELECT_MAP
        CameraFOV = 61.0f;
#endif //PJH_NEW_SERVER_SELECT_MAP
    else
    {
        if (World == WD_74NEW_CHARACTER_SCENE || World == WD_73NEW_LOGIN_SCENE) // Fix for opening scene and character selection
        {
            CameraZoom = 0;
            AngleY3D = 0;
        }
        CameraFOV = 35.f + CameraZoom;
        if( !g_pUIManager->IsInputEnable())
        {
            if (m_CameraOnOff == 1)
            {
                if(HIBYTE(GetAsyncKeyState(109))==128 || HIBYTE(GetAsyncKeyState(VK_PRIOR))==128) // PAGE UP or +
                {
                    if (CameraZoom < 12) CameraZoom += 2;
                }
                if(HIBYTE(GetAsyncKeyState(107))==128 || HIBYTE(GetAsyncKeyState(VK_NEXT))==128) // PAGE DOWN or -
                {
                    if (CameraZoom > -12) CameraZoom -= 2;
                }
                if(HIBYTE(GetAsyncKeyState(VK_RIGHT))==128) // RIGHT ARROW
                    CameraAngle[2] -= 4;
                if(HIBYTE(GetAsyncKeyState(VK_LEFT))==128) // LEFT ARROW
                    CameraAngle[2] += 4;
                
                if(HIBYTE(GetAsyncKeyState(VK_DOWN))==128) // DOWN ARROW
                    if (AngleY3D < 5) AngleY3D += 1;
                if(HIBYTE(GetAsyncKeyState(VK_UP))==128) // UP ARROW
                    if (AngleY3D > -10) AngleY3D -= 1;
                if(HIBYTE(GetAsyncKeyState(VK_END))==128) // END keys for reset 3D camera
                {
                    CameraZoom = 0;
                    CameraAngle[2] = -45.f;
                    AngleY3D = 0;
                }
            }
            else {
                CameraZoom = 0;
                CameraAngle[2] = -45.f;
                AngleY3D = 0;
            }
        }
    } 

- In the same function, go to this condition and edit as follows

        else if(SceneFlag == CHARACTER_SCENE) // ŔĚÇőŔç - ÄɸŻĹÍ ľŔ Ŕ϶§ Ä«¸Ţ¶ó Ŕ§Äˇ ĽĽĆĂ
        {
#ifdef PJH_NEW_SERVER_SELECT_MAP
            CameraAngle[0] = -84.5f;
            CameraAngle[1] = 0.0f;
            CameraAngle[2] = -75.0f;
             CameraPosition[0] = 9758.93f;
             CameraPosition[1] = 18913.11f;

            CameraAngle[2] = -30.0f;
            CameraPosition[0] = 23566.75f;
            CameraPosition[1] = 14085.51f;
            CameraPosition[2] = 395.0f;
#endif //PJH_NEW_SERVER_SELECT_MAP
        }
        else
        {
            CameraAngle[0] = -48.5f;
            if (m_CameraOnOff == 1)
            {
                CameraAngle[0] += AngleY3D;
            }
        }
#endif 

- At the end of this function, add the following condition before return bLockCamera;

    // Field of vision
    if (m_CameraOnOff == 1)
    {
        if (CameraZoom > 0)
            CameraViewFar += 458.33f + (458.33f * CameraZoom);
        else 
            CameraViewFar += 1458.33f;
    } 

- Go to the MoveMainScene() function and modify this condition. Thus...

            g_dwKeyFocusUIID = 0;
            if(GetFocus() != g_hWnd)

        if( ErrorMessage != MESSAGE_LOG_OUT )
            g_pUIManager->UpdateInput();
    } 

- Go to the next condition in the MoveMainScene() function and edit that condition. Thus...

    if(!CameraTopViewEnable 
        || m_CameraOnOff == 1) // <= 3D Camera
        MoveItems();
    if ( ( World==WD_0LORENCIA && HeroTile!=4 ) || 
         ( World==WD_2DEVIAS && HeroTile!=3 && HeroTile<10 )

        || IsUnitedMarketPlace()
#endif    // LDS_ADD_MAP_UNITEDMARKETPLACE
     )
    {
        MoveLeaves();
    } 

- Go to the next condition in the RenderMainScene() function and edit that condition. Thus...

    BYTE byWaterMap = 0;

    if(CameraTopViewEnable == false 
        || m_CameraOnOff == 1) // 3D Camera
    {
#ifdef MOD_MAINSCENE_HEIGHT
        Height = 480;
#else //MOD_MAINSCENE_HEIGHT
        Height = 480-48;
#endif //MOD_MAINSCENE_HEIGHT
    }
    else
    {
        Height = 480;
    } 

- And the last condition in this file in the RenderMainScene() function modify this condition. Thus...

    RenderCharactersClient();   //  Äł¸ŻĹÍ ą¦»ç.

    if(EditFlag!=EDIT_NONE)     //  żˇµđĹÍżˇĽ­¸¸ Ăł¸®.
    {
        RenderTerrain(true);
    }
    if(!CameraTopViewEnable 
        || m_CameraOnOff == 1)    // <=  3D Camera
         RenderItems(); 

3. Problem with rotating figure and head when moving the cursor.
Webzen did not expect that someone would create a 3D camera. Because of this, an abnormality will appear when the camera is turned to the right or left side.
- Go to the ZzzInterface.cpp file and find the MoveHero() function. Modify the following condition as follows.

    //  ! ¸¶żě˝ş µű¶óĽ­ Äł¸ŻĹÍŔÇ Č¸Ŕü °˘µµ¸¦ şŻ°ćÇŃ´Ů.
    if( g_isCharacterBuff(o, eDeBuff_Stun)
        || g_isCharacterBuff(o, eDeBuff_Sleep)
#ifdef WORLDCUP_ADD
        || o->CurrentAction == PLAYER_POINT_DANCE
#endif //WORLDCUP_ADD
#ifdef PBG_ADD_NEWCHAR_MONK_SKILL
        || o->CurrentAction == PLAYER_SKILL_GIANTSWING
#endif //PBG_ADD_NEWCHAR_MONK_SKILL
            )
    {
        Angle = (int)Hero->Object.Angle[2];
        bLookAtMouse = false;
    }
    else
    {
        if (m_CameraOnOff == 1)
            Angle = (int)(Hero->Object.Angle[2]+CreateAngle((float)HeroX,(float)HeroY,(float)MouseX,(float)MouseY)) + 360 + CameraAngle[2];
        else
            Angle = (int)(Hero->Object.Angle[2]+CreateAngle((float)HeroX,(float)HeroY,(float)MouseX,(float)MouseY)) + 360 - 45;

        Angle %= 360;
        if(Angle < 120) Angle = 120;
        if(Angle > 240) Angle = 240;
        Angle += 180;
        Angle %= 360;
    }
        
    Hero->Object.HeadTargetAngle[2] = 0.f; 

- Find another condition and edit it like this

        if(StandTime >= 40 && !MouseOnWindow && !Hero->Dead &&
            o->CurrentAction!=PLAYER_POSE1 && o->CurrentAction!=PLAYER_POSE_FEMALE1 &&
            o->CurrentAction!=PLAYER_SIT1  && o->CurrentAction!=PLAYER_SIT_FEMALE1 && NoAutoAttacking &&
            o->CurrentAction!=PLAYER_ATTACK_TELEPORT &&
            o->CurrentAction!=PLAYER_ATTACK_RIDE_TELEPORT &&
            o->CurrentAction != PLAYER_FENRIR_ATTACK_DARKLORD_TELEPORT &&
#ifdef PBG_ADD_NEWCHAR_MONK_SKILL
            o->CurrentAction != PLAYER_SKILL_ATT_UP_OURFORCES &&
            o->CurrentAction != PLAYER_SKILL_HP_UP_OURFORCES &&
#endif //PBG_ADD_NEWCHAR_MONK_SKILL
            Hero->AttackTime == 0)
        {
            StandTime = 0;
            if (m_CameraOnOff == 1)
                HeroAngle = -(int)(CameraAngle[2]+CreateAngle((float)MouseX,(float)MouseY,(float)HeroX,(float)HeroY)) + 360;
            else
                HeroAngle = -(int)(CreateAngle((float)MouseX,(float)MouseY,(float)HeroX,(float)HeroY)) + 360 + 45;

            HeroAngle %= 360;
            BYTE Angle1 = ((BYTE)((o->Angle[2]+22.5f)/360.f*8.f+1.f)%8);
            BYTE Angle2 = ((BYTE)(((float)HeroAngle+22.5f)/360.f*8.f+1.f)%8);
            if(Angle1 != Angle2)
            {
                if ( o->CurrentAction!=PLAYER_ATTACK_SKILL_SWORD2 )
                {
                    Hero->Object.Angle[2] = (float)HeroAngle;
                }
                SendRequestAction(AT_STAND1,((BYTE)((HeroAngle+22.5f)/360.f*8.f+1.f)%8));
            }
        } 

Now, even when moving sideways, the figure and head will rotate behind the cursor.

4. The distance of drawing objects from the character
- Go to the ZzzLodTerrain.cpp file and find the function bool TestFrustrum2D(float x,float y,float Range). Edit it as follows.

bool TestFrustrum2D(float x,float y,float Range)
{
    if ( SceneFlag == SERVER_LIST_SCENE || SceneFlag == WEBZEN_SCENE || SceneFlag == LOADING_SCENE)
        return true;

    int j = 3;
    for(int i=0;i<4;j=i,i++)
    {
        if (m_CameraOnOff == 1)    
        {
            if (CameraZoom > 0)
                Range -= ((50.f/2.5f) * CameraZoom);//Range -= 600.f;
            else
                Range -= 50.f;

            if (AngleY3D < 0)
                Range += 15.f * AngleY3D;
        }

        if((FrustrumX[i]-x) * (FrustrumY[j]-y) - (FrustrumX[j]-x) * (FrustrumY[i]-y) <= Range)
        {
            return false;
        }
    }
    return true;
} 

- Then find the function bool bool TestFrustrum(vec3_t Position,float Range). Edit it as follows.

bool TestFrustrum(vec3_t Position,float Range)
{
    for(int i=0;i<5;i++)
    {
        float Value;
        if (m_CameraOnOff == 1) 
        {
            if (CameraZoom > 0)
                Range += 0.f + ((41.66f/2.5f) * CameraZoom);//Range += 500.f;
            else
                Range += 41.66f;
        }
        Value = FrustrumFaceD[i] + DotProduct(Position,FrustrumFaceNormal[i]);
        if(Value < -(Range)) return false;
    }
    return true;
} 

[BONUS]
5. Fog around field of vision.
Another problem is rendering objects while walking. Objects just disappear and it looks ugly. This problem can also be solved.

- Go to the ZzzOpenglUtil.cpp file and find the void BeginOpengl(int x,int y,int Width,int Height ) function. Adjust the fog condition as follows.

    glDisable(GL_ALPHA_TEST);
    glEnable(GL_TEXTURE_2D);
    glEnable(GL_DEPTH_TEST);
    glEnable(GL_CULL_FACE);
       glDepthMask(true);
    AlphaTestEnable = false;
    TextureEnable   = true;
    DepthTestEnable = true;
    CullFaceEnable  = true;
    DepthMaskEnable = true;
    glDepthFunc(GL_LEQUAL);
    glAlphaFunc(GL_GREATER,0.25f);

    if(FogEnable) 
    {
        if (m_CameraOnOff == 1)
        {
            glEnable(GL_FOG);
            glFogf( GL_FOG_MODE, GL_LINEAR );
            glFogf(GL_FOG_START, 2000.f);
            glFogf(GL_FOG_END, 2700.f);

            glFogf(GL_FOG_DENSITY, FogDensity);
            float color[] = {10/256.f,10/256.f,10/256.f,5.0};
            glFogfv(GL_FOG_COLOR, color);
        }
        else 
        {
            glEnable(GL_FOG);
            glFogi(GL_FOG_MODE, GL_LINEAR);
            glFogf(GL_FOG_DENSITY, FogDensity);
            glFogfv(GL_FOG_COLOR, FogColor);
        }
    }
    else
    {
        glDisable(GL_FOG);
    }

    GetOpenGLMatrix(CameraMatrix); 

- Go to the ZzzScene.cpp file and find the RenderMainScene() function. Replace the following line

FogEnable = true; 

with this line

FogEnable   = (m_CameraOnOff)?true:false; 

If you did everything right, your 3D camera is now almost ready.
When I finish the other edits I can provide them as well.

During this tutorial I modified the code to make it faster. It's not a win.

@leorond you can change map login server and select character to EX700 ?

@leorond you can change map login server and select character to EX700 ?

It's not hard, can you provide the maps you want there?

I don't have these maps and objects.
