(OpenCL seems to not be working right now, right? When activated render got stuck)

Tried 2.8 two weeks ago rendered quite complex scenes openCL.
Does Luxmark 3.1 run openCL on your system?

Addition to idea 2 Although each core has its own camera and sub-image it might be useful to create a central virtual image Z times larger as the sub-image. Assuming there are three possibilities: a) path ends on sub-image b) path ends outside sub-image but inside image c) path ends outside image I...

I can do it in Cycles, but can't work out how to do it correctly in Lux.

Could someone please upload a basic node setup or scene for me to learn from?

Many thanks

Did you read and follow B.Y.O.B‘s post already?

The reason for the monolithic look of material Null homogeneous in former image is: normals have been inside out. The outer blueish c...

VRAM-RAM-swapping? Never observed with my old graphic cards. In much earlier LuxCoreRender versions not enough VRAM lead to crash. Six to eight weeks ago crash had been fixed, an error message appears instead. I guess the stats are wrong. AMD Vega 56/64 supports swapping GPU RAM over CPU RAM so you...
