Luxcore Optix crash investigation

Post by Sharlybg » Sat Sep 26, 2020 3:15 pm

Just trying to track the 2.5 alpha repetitive crash. And it look like Optix can be related to that at some degree.

first scenario

I just found that being in Viewport GPU preview rendering (CUDA) Disable or enable optix during the render prview and then switch back
to solid view crash blender even with the cube instantly and reliablelly ;) .

Lastest Blendluxcore with Nvidia driver 452.06.

Second Crash scenario :

Switching from CPU to GPU while rendering in viewport (even without viewport denoiser enable) and back to solid view will instantly close blender : reproductible even with a CUBE.

I have not yet started looking into it.

Sorry to ask about it again :mrgreen: do the last build have any improvement arround this issue.It make optix denoiser very hard to work with because switching between viewport mode and device will crash again and again. :|

Windows 10 / blender 2.83.6 / BlendLuxcore (build this day) / driver Nvidia 456.38

Hi,

I see the same crash situations (ex: switch between solid and render) with the default cube.
Is there a solution to solve these problems, please ?

Thanks so much.
