I wanted to ask about a certain issue with seeing objects through transparency that seems inconsistent to me.
In the above picture, I have a sphere inside a partially transparent blue slab. The sphere is correctly obscured by the slab.
However, in this picture when I move another slab onto the blue slab and sphere, without changing anything else, suddenly the sphere is uncovered and fully visible.
Is there a way to fix this so that the sphere is obscured properly?
