Hello, I might be missing something but it looks to me that (in 5.4.2p2) real-time lights are not working correctly with static geometry. The picture attached is a very simple setup: Floor and walls are static but the right one The sculpture is non static geometry Directional light in mixed mode Spotlight is real-time (red colour) Pre-computed real-time and baked GI are enabled with default parameters Render path is deferred with linear colours What I'm getting: The spotlight direct illumination is visible at the non-static geometry (sculpture and right wall) but not affecting the back wall that is static geometry. Bounced light from the spotlight is visible at the floor though. If I enable "Important GI" to the back wall the direct light is visible. I was expecting the spotlight to affect both static and dynamic geometry. Am I wrong and this is the expected behaviour? Am I missing something to make it work as I want to or is this a bug?
