So I'm currently attempting to create a realistic eye using a specific workflow that uses masks:
The one I chose to follow was this one by: https://gumroad.com/tomnewbury
He said that this method can be used with other renderers and for my project I'm currently using V-Ray.
So from reading the title you can see that I'm having an issue with the Blend node in Maya on this specific part where I connect the sclera and cornea shaders (VRayMtl nodes) into the BlendColors node: YouTube example: https://youtu.be/8gwIbBqn5No?t=27m35s
When I do this with the VRayMtl shaders, I get this 'unsupported' error:
(When I render, the eyeball is completely black)
So my question is.. how do I do this method using V-Ray? (how do I make a specific area of a shader transparent using a mask so that the iris is visible?)
Would be really grateful if someone could help!
