I’m using Lumen and getting some bad light bleed in my interior.
You can tell clearly where the walls meet the ceiling there is a lot of bleeding, and it’s even more noticeable when the camera is moving.
My walls and ceiling are aligned and mesh cleanly and they do not intersect. I tried with both adding 10 cm of volume and keeping them flat planes, but it does not appear to make a difference.
I have a rectangle light, a sky light, and a directional light. This bleeding occurs when the sky light and/or the directional light is enabled. It happens whether they are set to static or stationary. It is when dynamic shadows is enabled that this happens.
Is the screenshot from the post-render, or from inside the Editor? You may be able to add more cards in order to fix the problem!
I hope this can help!
You ever get a fix for this? I’m having the same issue. I’m starting to think Lumen is worthless with all the light bleed issues and “moving” noise that is random on different surfaces.
