DitherFade material layer breaks glTF alphaMask rendering #1320

Closed kring closed 9 months ago

kring commented 9 months ago

Tilesets that use glTF's alphaMask property to do masked opacity don't work correctly. The objects are rendered opaque even in the masked region. The problem is the DitherFade layer in our default materials. The MLB_DitherFade replaces the opacity mask with the one from the dither. It should multiply instead.

This is a duplicate of #1311. I'll update that issue instead.
