Bumping Post. I am running into the same issue. When I open the model viewer, I get the UI but in the view screen its all black. The whole program becomes non responsive in the task menu. I then have to end the program in the task manager to close it. This sometimes happens when I open other 3d viewers like when you double click on any .fbx file. (most of the time this does not happen. Ive tried doing a clean reinstall of both the game and the Modd tools. This is will the viewer on the meshes in the resource finder but not the model viewer.
I havent used this tool before, but recently I also found that in the vanilla game, when I go to make a character, after the clan selection. The left side of the menu does janky stuff like stay on the culture picture. If i press back and click my culture again, it seems to work fine. I dont know if the two is related but both happen even after a clean reinstall.
I can provide pictures after my 24 hour freeze on making a new account.
