Hello there.
I just had a problem with 3ds max and blender and i solved it.
Now i want to share the solution.
So this is what happens:
You want to make a character for lets say your game.
Then you import it as .HMX into Blender and export it to .obj
Now you want to import it into 3ds max but this is what happens:
Polygon-index error
Solution:
Go back into blender and export as: .3DS and it should work now!
All textures will stay in tact!
