It is quite a long and computer taxing process taking a model from max and importing it into UnrealEd.

It is possible to import .obj files into UnrealEd but it wont thank you for it. I have a converter that will allow you to save your models as a UnrealEd "brush" which creates .t3d files.

After that its just a matter of alot of waiting while your brush is imported/exported, moved and built. God forgive you if you click "build all" and dont really mean it.

Back to Unreal the level went. You can take the level from here, just place the level in your UT2004/maps folder.
