Compiling Error.

well would that have a tutorial on how to create custom maps in 3ds max?

There are video-tutorials like that yeah. Try a search for it.

well im thinking that im doing everything right, but its just this one error thats happening.

Yes i suggest getting a good video tutorial also. If its just a box with 1 material and the b_levelroot it should compile. Thats a real early error also.

Check these 2 things.
1, Is your b_levelroot attached correctly?
2. Are your shader(s) correctly used?

Oh with that exporter your map needs to be editable mesh. Make sure that is the case also.

well i have no clue what a b_levelroot is and havnt used materials.

Have a look here, personally i liked the one from cheesexxn1ps.
