I’ve attached screenshots including UV maps to visually explain. For my character’s eyeball, I have two spheres (the main eyeball and the outer transparent/specular sphere).
Eyeballs look fine in Maya because I have transparency and specular set up in material attributes. When I import my model into Mudbox or Unreal Engine for example, the outer sphere loses transparency . I’m not sure if the specular stays or not. Maybe it does?
How do I get both (transparency / specular shine) to stay when I import into Mudbox or especially a game engine? Do I have to make a separate specular texture map or something? How do I achieve this so outer spheres aren’t a solid grey?
