You cant just willy-nilly import ripped mesh and expect to be able to export it ezpz.
3d rips always require medium-heavy editing, draw calls contain unassigned/unused verts from other drawcalls.
The plugin cant do jack-poop with verts that dont belong to a polygon, therefor -> crash.
Same goes for radiant, besides that light wouldnt illuminate anything realy.
Also, max isnt like radiant where its wysiwyg* collision wise, read mine and wucas's posts.
Theres no map import plugin, why? because its not needed when you have the scene's max file since you created that scene.
This is logic, which is why maiet never bothered to make one, its just obsolete and not needed.
Oh and id say come up with your own content instead of editing existing content.
