Artifacts when baking with Irradience map #218

Closed michax closed 7 years ago

michax commented 7 years ago

Hi,

With latest version of blender (b9008f4), I noticed that baking with Irradiance Map is broken. I get lot's of artifacts, and precision of Irradience map seems to be static, despite changing subdivision min/max.

I tried changing around interpolation types and lookup methods. But I only got worst results. Baking previously worked without major problems with default Irradiance Settings.

Above issues occur whenever I pair Irradiance Map with Brute Force or Light Cache.

In addition, Light Cache takes now forever to finish when Baking. It takes around 40s to finish for simple scene, when before it was almost immediate.

I've checked same scene against 2.77 default GI settings (Irradiance + Light Cache). Whole scene renders in 11s, Light Cache takes around 0.7s. No artifacts.

Good

@michax this should be fixed with latest nightly.
