Recently I came up with a problem while importing the .fbx object file from moho into unity. Nothing seems to work with those ones, especially with materials of object. When I go to Project tab and open asset it shows “No name” material, but the whole model is white. I would be SO grateful for someone to help me with this one, it’s getting very annoying.

The “can’t start with negative vertex” error sounds like either:
your FBX is corrupt in some way.
you are using some FBX feature that isn’t supported by Unity’s importer.
Isolate, isolate, isolate, just standard engineering troubleshooting: make a cube, export it, see if that can come in.
If it can’t, try another format from this Moho thing, perhaps the Wavefront (.obj) format, which Unity can also read.
Alternately, pull it into something like Blender and see what Blender thinks. If that works, maybe re-export it from Blender.
Thank you for the reply, I’m going to experiment with my rig in Moho.
I’m curious if you sorted this out. I’m considering using Moho for my project and this is concerning. I’ve heard other complaints about the import process that makes me think twice. Thanks!
You could probably do a few small tests in less time than it took to read and make a forum post. 
The support boards for Moho might be another place to enquire. Unity is one of the most popular game engines in the world so you’re not the first person to consider doing this.
Let us know what you find!
