Using GPU with 0.8dev versions

[Dade]

Yes, i think that too. How is it possible that if it works SLG hybrid mode does not work.

then it is another problem... and I have no idea what can be.

when I click it (for render) just does nothing. What is OpenCL plataform index:0 ? Is OK the default value? (0)

I already set Renderer: Hybrid (CPU + GPU) and Surface Integrator: Path.

You have also to set the light strategy to "ONE".

It could be useful to try run LuxRender directly from command line and to load the exported scene by hand: if the rendering doesn't work, there should be an error reported in the log tab.

P.S. OpenCL plataform index 0 should be correct (i.e. means the first platform available).

Thanks you very much!!!

I did not know that. The light strategy thing... I set it in "ONE" and rendering...

Again, thanks, any way hybrid is to slow, I justo wanna try...

I love LuxRender, the interface and materials, but SLG work faster than luxrender

Hello,

I have downloaded luxrender for blender and I am having problems of blank screen with 0% gpu. In both cases it is unable to load render result from untitled.png But in internal it is always updating scene with 0% GPU and I cant cancel it. I need to kill whole blender.

System:
Win 7 64
Ati HD4850 512MB
Intel Dual core 3GHz
Latest catalyst - 11.6 with OpenCL

I have the excact samegpu and i have the same issue,
I had looked into it testing many different drivers, and i found out that the drivers before last october worked, when the stream drivers were named APP, After these drivers all the newer ones dont work with luxrender hybrid.

Its a bit strange though that all the newer ones work very nice with SLG.

After these drivers all the newer ones dont work with luxrender hybrid.

I have read some success report with latest 11.7beta ... they have probably broken something with 11.6.

Hey dade ive told many people with 58xx series to try the 11.7 and they all solved their issues
Unfortunately the 48xx series for me and for some others ive come across here dont work with drivers over 11.1 (maybe even older im not quite sure cause i uninstalled them 1 week ago to try the 11.7 beta ones which although they gave better results in luxmark they still dont work under lux)

I'm afraid they don't care very much of HD4xxx support anymore.

After installing ati catalyst 11.1 Iam having the same problem.

well I've tried drivers from 11.3 to 11.7, luxrender up to 0.9 dev - still getting the black screen. SmalLuxGpu and Luxmark is using both my 5850 cards with no problems. Its kinda irritating, I love luxrender but hate to use it with my slow cpu while my gpus are doing nothing.
