Partner Team Reporting:

Everbloom Games

Verification builds:

All Render Dragon versions (e.g. 1.16.200.01_rc0 renderdragon)

Summary:

Faces with the entity_alphablend_nocolor material rendered from the first person renderer are no longer visible.

Impact:

This prevents us from using semi-transparent textures for things in first person, such as screen overlays.

Repro Steps:

1. Open the provided world
2. Head to the magenta-floored chunk
3. Press the button on the command block labeled Screen Overlay

Expected:

You should see a white gradient coming from the bottom of your screen.

Observed:

Nothing seems to happen.

Screenshots/Videos attached: Yes/No
