I've been having trouble getting a model imported into FaceRig for the past week and I've been able to troubleshoot almost all of my issues except this last one.

First of all, I'm had problems running the new Model Importer because I was trying to open it through a "C:/Program File (x86)" file path and it wouldn't open because of the spaces. I mounted another hard drive and reinstalled the program but this time on a non-space riddled file path. I've got the importer to open, and have been able to load my data files, and the textures, and the animations just fine, but then when I click on Import, the script runs for a while before breaking at a certain point.

The error I get is here: https://pastebin.com/FuHgHFpj

When trying to search for similar assert fails it seems that the issue might have to do with hardware. However, I have a pretty robust video rig that can run most contemporary games at ultra or very high performance settings. I tried setting the FaceRig Launcher to dx9 to see if that would make a difference, but I get the same error.

So this is an problem, but also when I try to import the mesh it says there are loads more vertices than what are in my actual mesh. I've used MeshLab to double check my face/vert count and it is well below the limit of what it normally expects.

Any helps/advice would be really appreciated!
Hoping to hear back from the developers as well :)
