Lamps

[Asticles]

I've made a little test with a couple of lamps and dof.
I attach the scene but materials keep disconnected when I reopen it.

Great image. The disconnecting of the materials is a known bug in blender which has been reported by B.Y.O.B. th the blender devs. The fix is now in trunk and will be part of a 2.79a release.

I tried this scene with the settings OpenCl : Path : Metropolis and has been crashing.
Sobol works fine.

[B.Y.O.B.]

Check if your graphics card runs out of memory.
Metropolis sampler needs more VRAM than Sobol.

The problem is that currently not having the choice to select GPU device lead every opencl calculation to include intel integrated device. humm i guess .

You can switch off "Use CPUs" and it should only run on your graphics cards.

Only all installed discrete GPUs ?

[B.Y.O.B.]

I think all GPUs with OpenCL driver installed.
In the background, these checkboxes are setting the properties

Code: Select all

opencl.cpu.use

and

Code: Select all

opencl.gpu.use

So in my case intel IGP will run.

Intel integrated GPU is ... not ... good, just don't use it, the are not designed for GPU computing. I assume BlendLuxCore doesn't yet support single OpenCL device selection, it is possible and I guess it is only matter of time before its arrive.
