LuxCore not rendering on CPU #626
Description
I'm trying to render glass with caustics. When I select CPU, it processes apparently normally, i.e. the processor gets at full power and the samples counter adds up at some samples/second. But I get only the background rendered, i.e. black or a HDRI, if there is one. It happens for both light integrators — pathtracing and bidirectional.
When I select GPU with OpenCL or CUDA, it renders normally, but Light Tracing, which is required for caustics to work, is not visible, because it is done on the CPU. So I get the rendered image with no caustics.
Tested with LuxCore Blender 2.6 on Blender 3.6 and 2.8 Alpha on Blender 4.0.
