The update is incredible but :
1- SunActor makes the whole image white when used with the path tracer. ( It works well with lit mode). And i have noticed some strange behaviour when used with baked lighting.
2- SunSky actor + HDRI Actor when used together this happen :
-
you will need to cranck up the intensity of the hdri forba value higher than 10000 whicc will make unlit mode completely white
-
using both actors introduces 2 skylight components which is not friendly at all.
