Shader complexity problem in preview mode , bug

Shader complexity in mode shows all objects in red , even those have very basic materials(basic materials in mobile starter content). is this a bug ?

Wondering the exact same thing. Is this feature broken for preview mode?

This still seems to be an issue even with materials that are unlit and have just a simple colour in the emissive.

still doesnt seem to be fixed or I’m I missing something?

sadly still not fixed so i am doing forum necromancy.
I have a range of materials from simple colors to layer landscapes and EVERYTHING is red.
watched a couple videos and went through documents. ANYTHING that said it reduced the shader count I set it to that setting.

obviously i’m missing something as an attempt to load still tries to compile 25K+ shaders (does 800 when I build/play on PC) ugh
