Issues with my Model

I made my model in Maya, exported as an FBX, and brought it into Mudbox. It has a weird look to it and I get a message saying there was an issue importing it. Painting it is laggy and, well goes oddly. Here’s what it looks like:

See what I mean?

What could be the problem?

P.S. This has been happening a lot lately.

Hmm there are some problems which i faced when i was working with mudbox, well first of all if you use Boolean (in max) (which i don’t know what they call it on Maya) you will have segments problem and you can’t add new res on it, second you can have normal problems, and finally maybe some of the vertexes didn’t weld together and that cause problems too…try to make clean and simple model as you can…

Ok, I made a new one by just extruding boxes. I got the same result. Any ideas? I don’t know how to make a simpler model.

It should work alright to be honest! add some pics of your model on maya and mudbox so that i can understand better!

BTW you should unwrap the model too for painting…

That defeats the purpose of using Mudbox…
