LuxCore not rendering on CPU #626

Open lgmventura opened 8 months ago

lgmventura commented 8 months ago

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.

System:

Please upload a test file which show the problem.

Test file

neo2068 commented 8 months ago

For me, the file renders fine. Can you explain the problem more in detail and make screenshots? 20240103 - copo

lgmventura commented 8 months ago

Rendering with CPU as compute device: CPU, Pathtracing

Using GPU as compute device: GPU, Pathtracing. No caustics visible.

lgmventura commented 8 months ago

@neo2068 what other information do you need? Everything rendered on the CPU gets invisible, except for the background colour/sky/HDRI. What could be the cause? Do you suggest some test for me to do?

lgmventura commented 8 months ago

I just found the version 2.61 is working fine with Blender 3.4.1. So it must be some regression with the newer versions.

neo2068 commented 8 months ago

Thanks for the screenshots. It is very strange. Are there any error messages in the console?

lgmventura commented 8 months ago

Thanks for the support. When opening Blender, selecting LuxCore as rendering engine and rendering the default cube without changing anything, I get for Blender 3.41:

Here the cube gets rendered normally with the CPU. I pressed ESC to stop it after the 4th noise estimation log message, so I manually wrote the ... at this place. After pressing ESC, that last message about the video card came out.

Here, the cube doesn't get rendered using the CPU, what corresponds to the log messages here. I see only the sky (default background) as if the cube were invisible. But I get these very small noise estimation values in the log.

@neo2068 I just found out, if I open Blender 4.0.1 with BlendLuxCore 2.8alpha1, select LuxCoreRender as render engine and viewport shading as Rendered, Blender crashes. The log file in /tmp/blender.crash.txt contains:
