I've tried the override material with the eyes on every skin using the irisframe 0 and 1 int materials, especially but the eyes still are closed. Could I get a little help? I'm typing it as "$irisframe1" on the eyeball_r and eyeball_l (and so on with the other eye skins). Am I doing this right?

@Mr.MechaG
I'm sorry for the really late response.

You'll have to adjust the eyelid flexes to make them open.
It's in the unknown section of the model when looking through him through the anim set editor, I think.

Thank you so much, this really helped, got it working. Sorry about my late response.
