Hi,
Following the guidelines of the Issues page, I'm creating a quick forum thread for this (and I'll likely be posting a couple others over the next couple of days, hence why this text is quoted).
Alright, so from the looks of things, RenderTextures do not have any internal support for a stencil buffer, although you are certainly free to request a depth buffer. I'm curious: is there a particular reason for not having an optional stencil buffer implemented? And if not, could we discuss a good way to implementing it/what would be needed?
