Let me illustrate what I meant when I said that objects are not rendered correctly far from the point of origin (blacks artifacts).
It is not a configuration issue, because I tried all the possible wrongs scenarios: GI configuration, odd numbers in renderer, unmapped UVs, n-gons, flipped normals, Cache, and everything you can imagine. increasing the GI cache Detail and Quality seems to get it better, but never enough. the only thing i can think about, is a TG's bug, because when i bring the object to the origin point again, it render correctly again. i would like to ask if anyone can check if this bug is a fact or is only me?
