Specular scale bug with macOS Catalina

[PenguinvilleRescue1 (Penguin)]

Hi,

For a while (since the rollout of Future is Bright Phase 3), turning the EnvironmentSpecularScale setting to anything more than 0, parts with certain materials (e.g. Brick, Fabric, Metal) have red, green, or sometimes white highlights. This bug only occurs when a game has ShadowMap enabled and my Graphics Mode set to Metal.

with ShadowMap

with Future

Here are my system specs:

We’re able to reproduce this bug now with an Intel running Metal and non-zero EnvironmentSpecularScale. I’ll post an update here when we have a fix.
