So I am building a scene to render as a diorama. There’s a building on a ground plane, with a basement entrance. The only problem is, you can see the basement through the backfaces when you look at the scene from the side.
If it’s at all possible, I’d like the basement to not be visible at all from this angle, as it’s my main camera angle. I was curious if it’s possible to make this part of the mesh invisible when viewed THROUGH the backfaces? Either through material work or even scripting if necessary. I want to avoid just covering it up because I like my composition… Thoughts?
You need to create a mask within the material that can control the visibility. The pixels do not know arbitrary things like if it’s being viewed through a different backface.
This node setup will create a circular mask you can use to control the opacity of a masked material. Anything inside the radius would be visible, anything outside would be invisible.
