BTW, I think an alternate skin was found for Blade Nia and I already made a VRchat model, I can give you the unity files if you want them. I will probably extract the files myself to confirm if it is in the game, but the skin looks awesome in my opinion.
Just realized while playing XC2, that most characters including Nia don't actually move their eyes, so it would be almost impossible to get the eyes to move with the skeleton used in game
Unfortunately, the models eyes were made using 3ds max and blender has trouble trying to find the shape keys made by 3ds max. From what I cna tell, the fbx file lost alot of polygons including shape keys since the raw file 122k faces, while the fbx only has 22k. The best solution I found was to make the eyes 3d by adding a sphere and textures, then parenting it to the head. I know that when I got the model from vgresource, the guy who dumped it also made the pyra model and he added the 3d eyes to it. Hopefully someone will come up with an easier method.
Thanks, I finally got the eye movements working after about a week of editing when the model got released, but the mouth shape keys were way to difficult for me. Great job on the animations btw. Now to work on particle effects for the sword. Best Blade ever
