If I had to guess, I’d say the eyes are probably using a texture (bitmap) that isn’t being imported along with the FBX. I see you selected “Embed media” which I think should have exported it, but check your UE4 contents to see if it’s in there.
I see. Then it’s probably one of 2 things. The eyes don’t have the right material applied to them, or the texture sample isn’t being piped into the material correctly.
I would open up whatever material is being used on the eyes.
That’s a good question, I couldn’t tell you how they intended to use those textures, however if you take the top pin of the top texture and plug it into the base color of the material, you should at least be able to see them.
You might also need to plug in a TexCoord node into the UVs.
It’s too complex for me. The eyes are made up of multiple objects with several different UVs and some translucent materials, I don’t know how to export them in a way that UE4 can understand.
