Mixed Light + Static = No Specular

I’m not getting specular reflections from static GameObjects that use the Lit or SimpleLit shader when they are lit by (only) one directional, mixed light. If I switch the light to realtime, I get the specular reflections. I have Mixed Lighting enabled in the renderpipeline asset.

Is this a bug, or just missing in the docs?

Looks like it only occurs when the light has shadows enabled.

EDIT: I doesn’t matter if the pipeline setting has Lighting>Main Light>Cast Shadows on or off

Also occurs with the Lit shader.
If I change the object to non Static, it shows the specular reflection.
(URP 7.3.1, Unity 2019.3.13f1, Metal)

Maybe only shadowmask modes (not supported in URP) support specular on lightmap static objects… I guess I’ll have to try and fake something with a custom SimpleLit derived shader, and some creative interpretation of the baked GI

Did you ever find a solution to this? As you stated, specular is thrown out the window the second shadows are enabled on baked lights. Can be fixed by adding an additional RT directional light, but the overhead …
