LuxRender 0.9-dev Linux build of 06-04-2012

[SATtva]

Hi guys,

New builds have finally made through. Please read Lord Crc's post for our progress in the last month, and minor problems the current code has.

LuxRender 0.9-dev branch:

• 32-bit, SSE: No OpenCL
• 32-bit, SSE2: No OpenCL
• 64-bit, SSE2: No OpenCL, With OpenCL

LuxBlend 0.9-dev:

• For Blender 2.49b
• For Blender 2.58
• For Blender 2.60
• For Blender 2.61
• For Blender 2.62 and above

Notes:

• LuxRender packages include Lux GUI, console, film merger utility, pylux and liblux shared library. Exporters for Blender are separate download links.
• If you get "Illegal instruction" error when starting the program, make sure your CPU supports SSE instructions set this particular build was compiled for.
• For OpenCL builds: If the program won't start because of libOpenCL missing, make sure you have AMD GPU drivers, latest nVidia drivers or Intel OpenCL drivers installed.
• For OpenCL builds: If you receive "/usr/lib/nvidia-current/libOpenCL.so: no version information available (required by ./luxrender)" warning, ignore it -- everything should work correctly nevertheless.
• To install LuxBlend 2.5/2.6 follow these instructions.
• In case of troubles installing LuxBlend 2.5/2.6 make sure you're using the right snapshot for your Blender version from the list above.

Thanks for the build.

Yep, thanks a lot.

I downloaded this linux build for 64bit sse2 with opencl
and luxblend for 2.62 and above.

I tried to render this scene
http://www.pasteall.org/blend/13321
and I can see luxrender launchs and it begins to eat memory until all the memory is consumed and then
Linux freezes. You keep clicking on the X button to close luxrender and eventually it obeys and close and your linux becomes
responsive again.

So I think there is something wrong in this luxrender build. Can someone test this scene and confirm? And perhaps to report to the developpers to take a look. The scene is just three planes, and 1 camera. 1 plane is a light and the other two are grey and pink.

I've seen this bug happen when using samplers other than metropolis with outlier rejection. I think it is something about the low discrepancy and random samplers that causes OR to get hung up. Can you try setting the firefly rejection value in the camera panel to 0 and see if that fixes it? At least that will help us narrow this down.

[SATtva]

Confirmed, the problem is really narrow: Bidir+(Random/LD)+OR. Switch any of these to anything else, and scene renders correctly. I'll file a bugreport.

Thanks Satva. I hope it gets fixed for next test build.
