Thank you. This explains the dark lights in combination with env. light. Did not know that this is intended behaviour.B.Y.O.B. wrote: ↑Mon Jul 16, 2018 8:22 amEdit: by the way, your light sources are very high poly. Consider using less triangles for them.
Currently you have 4536 light sources (emitting tris) in total.
Since they are all in one mesh, LuxCore will automatically switch off direct light sampling for those light sources (this happens with any emitting mesh with more than 256 triangles). This is done because usually, meshes with many triangles are not the main light source of the scene and would steal away computing power from the other lights, your scene is a special case.
Exactly, a warning helps in this case. Frist I‘ve used rectanlges. But this did not fit well to the scene. Looking forward to installing the next release. I will apply the array and separate the lights by loose parts. Reflector needs some improvements anyway.
