Hey. I had a project in 5.0 that had translucent shadows. Upgrading to 5.1 to fix a different issue I have lost the shadows.
I created a new project in 5.1, created a material with Blend Mode: Translucent and Lighting Mode: Surface TranslucencyVolume. Then I enabled Lighting > Advanced > Volumetric Translucent Shadows in details on the object. No shadows, even at full opacity. Can someone please help? Am I missing something?
