I’m having issues with a masked materials on forward shading and MSAA. All masked materials become translucent. I have no problem with MSAA and deferred rendering.

With MSAA:

With TAA:

You can reproduce it in Material\_Properties map (Content Example).

In your picture, the side of the material has artifact lines due to MSAA. Do you know how to work around that?
