Is there a way to make lumen not look like an animated blobby mess? I just want to have some static lights that dont look like they are refracted from wavy water…

Optimize a scene, give more light to the scene, use EBC)

EBC?

scene is optimized…

i found out emissive materials with lumen kinda suck… especially if they are coming from small surfaces.

Yep, that’s lumen for you. The devs get into the limitations a lot on their various livestreams, but the TLDR of good lumen behavior is this:

  1. You basically need hardware RT unless you want to be messing with a lot of per-mesh settings to get good GI. You literally need HWRT to get good reflections.

  2. Use analytical light sources next to dim emissives wherever you can if you want the look of emissives with stable lighting. If you do use emissive area lighting, make sure to make the emissive surface as big as you can and reasonably dim. Small, bright emissives will throw noise everywhere and it’s simply unavoidable, no matter how high you scale.

  3. If you absolutely need good quality, then go into the PPV and crank the lumen scene lighting quality and final gather quality as high as it will go. It will do a lot to make noise better at a massive GPU cost.

By the way, you say you’re just looking for good looking GI from static lights. If that’s the case, why not use lightmass?

unfortunately the way i set up my scene with detailed nanite meshes… if they intersect… it creates a harsh dark seem where the meshes meet. Regaurdless of lightmap resolution.
