Hi, Im trying to bake with only emissive lights,but my results are terrible. Is there anyone who can advise?
Hi Can you provide images of your lightmaps with the UV overlay, and also describe what you want the end result to look like, and what you have tried so far to get it to work. Thanks
At this point i just need healty lightmaps wiht my emissive lights I have tried large pack margin,hi lightmap resolution ,direct ,indirect values. My models uv1 sets overlapped is that a problem? uv2 sets generated from unity.
Please try to replace the emissive with a tiny area light for now. And then maybe crank up the direct samples since they are being used when sampling lights (etc are using the indirect samples)
Exactly what @AcidArrow said - bump up your Indirect Samples to around 4000, and your direct samples to 100. That should remedy the issue. Alternatively, for square/rectangular emissives, you can follow @JenniferNordwall suggestion - just replace them with area lights.
Im tested with a new scene but result is still bad.this is completed in 22 minutes this setting inappropriate for my target scene. What am I doing wrong, enlighten results are fine.
Your bake times have increased since you have Realtime Global Illumination turned on. If your scene and your lighting is mostly static, just turn it off and rebake again.
You are right, i forgot to disable Rt GI.Now time counter shows 18min. What do you think about quality? It is not acceptable , am i wrong?
My suggestion would be to reduce the Lightmap resolution from 40 to something like 15 (maybe even less, experimentation needed) and increase the indirect samples more (maybe double what you currently have, or more, experimentation needed). You can also fine tune the resolution per mesh with the "Scale in lightmap" parameter, but I can't give you specific suggestions, since I don't know how your scene is set up (but the idea is to decrease scale in lightmap a lot for huge meshes that don't need detailed lighting)
