Hey ,
I am facing issue after engine update my env after getting light
my Env without lights
To fix the lighting issue after the PlayCanvas engine update, check the release notes for lighting changes, recalibrate light settings (intensity, shadows, etc.), and ensure your materials or shaders are compatible with the new engine. If the problem persists, seek help in the PlayCanvas forums.
please see this post @usama_jalal : Black material starting today
