is it possible to do without creating it in blender? i want a diamond shape and its on this model i have in unity but thats a vrca file. im unable to open and it on my rindo i believe. im just a complete noob lol
Yep, there might be a blendshape you can use in unity on the face mesh! If there isn't, it would be fairly easy to make the edits to the head model in blender. Maybe you could make your own blendshape if there isn't one already!
