I’m currently working on a project in Unreal Engine 5.4 that involves creating non-Euclidean spaces, and I’m using Scene Capture to render certain areas (like portals). However, I’m running into issues with Lumen, as the lighting and reflections look different when seen through the Scene Capture camera compared to the main camera.
To solve this, I’m thinking about baking the lighting around the portal to make the area more stable and consistent, while still keeping Lumen active for dynamic elements in the scene. My goal is to maintain high-quality lighting around the portal without losing the benefits of Lumen for other parts of the scene.
Here are my questions:
Is there a way to bake Lumen’s lighting around the portal to avoid the discrepancies in the Scene Capture render?
If not, is there a recommended approach for baking lighting around static areas while using Lumen dynamically for other parts of the scene? I’m trying to prevent a harsh transition between baked light and Lumen in these non-Euclidean spaces.
Are there any tricks or settings that could help mitigate the issues with Lumen when using Scene Capture for rendering through portals?
Non-euclidean anything doesn’t feel like something UE is particularly suited for, but I think I see what you’re asking for.
Unfortunately, lumen and baked lighting are not useable concurrently. Either your scene is totally dynamic, or totally baked. Perhaps you could swap between them somehow, but the visual difference is enough that the seams would be quite obvious.
Honestly, if you’re deep enough in the engine to be doing non-euclidian stuff, I feel like you’d need a custom lighting solution at that point, something that’s stable in a way lumen simply isn’t.
