I’m experiencing some issues with lightmapping in v5.6.0f3. I’m baking a very simple scene with a single light, and a basic lit material. The result is that some objects will have opaque/black shadows in some areas, and not others. (There should be no black/opaque shadows anywhere).
Attached is a composition of what’s occurring, with some notes and explanation of the issue.
Some additional notes/strangeness:
- Enlighten takes ~2 hours for baked lighting in a simple scene (it used to take only several minutes with the same settings)
- Progressive lightmapper bakes the equivalent in ~5 minutes the first time, but future bakes are inconsistent.
- After the initial Progressive bake of ~1-4 minutes, following bakes for the same, unchanged scene report estimates back and forth between ~3+ hours to 20 minutes. (No changes to scene or lightmap settings).
- Regardless of time, after several progressive iterations, artifacts begin to appear in the lightmaps (the reason/examples for this post).
- There seems to be no way to clear lightmap data completely. (If the actual maps are deleted, along with the LightingData and ReflectionProbe data, future bakes are still instantaneous, displaying the same erroneous lightmaps are immediately as though the lightmap data is cached somewhere else).
