I wanted to create a mask for Instagram so I created a model of a character inside a mesh. This character has a face rig that can be animated with textures. It has an upper face with eyes and a bottom face with the mouth, each with a UV. I tried to export it as an .fbx, but these textures don't seem to work then.
Here are nodes for one part of the face (I used mapping to change tiles on one texture image)
Also I have multiple animations for this model made with Action Editor (they were made into NLA Tracks I think, I've never done multiple animations in one file before) and they also don't seem to work as I intended when exported. I exported with baked animations (key all bones, NLA strips, all actions, force start). The mesh and the character are different armatures.
Can someone explain to me what I'm doing wrong? Maybe there is another file extension I can export with that can preserve these animations? I'm fairly new to Blender.
