Maybe because its about a different kind of problem. Increasing lightmap resolution indeed solves problems ‘when’ the problem is related to insufficient size of the uvmap dedicated to the lightmap of the object concerned.
@ : my previous post went through the moderation and appeared before yours with a delay. When you mention increasing IndirectLightingQuality, does it only affect NumHemisphereSamples or also the parameters related to PhotonScale (NumDirectPhotonsScale / NumIndirectPhotonsScale / NumIndirectIrradiancePhotonsScale : parameters modified by Koola in his latest lightmass settings.) ?
Maybe I made a mistake somewhere but I’m curious to know if the observation I made in my previous post is correct : Koola parameters (involving Lighmass modification) vs. Klepadło parameters (no Lightmass modification & being faster).
It would be nice to have your insight on this if possible
