Please help, I have never used may before and so I edited a model I had by removing some stuff but when I try to send the model to mudbox it doesn't work and mudbox crashes and if I send it to 3ds max i can only see a botchy mess of some of the model and idk what is going on since I have just now started to try out maya (btw the model looks exactly the same as in 3ds max as it does in blender) please tell me what I should do ( I don't know my way around maya yet so I need it in detail and the crap behind the model are hallways and rooms and stuff for the building)
