Imagine you have an eye, like
- Eye Iris
- Eye Shape (Mask)
You could use Eye Shape layer clip iris. Nice to have. But, I do like to keep Eye Shape layer transparent. Is there a way without workaround?
Found the problem. I used official Blender 2.82.
Today I tried newest Blender 2.83 build. The masking system has changed and exposes a ‘mask’ checkbox.
With this Blender build I was able to get a working transparent masking shape.
