CUDA and CS6 Aerender.exe

Aerender.exe does not seems to use the CUDA on my Quadro4000 for raytraced comps. The command line shows that it sees the card, but all CPUs are pegged and render times are consistent with CPU render.

Has anyone else experienced this?

Thnx

Ensure that you have GPU selected for Ray-tracing, in the Prefs>Previews dialog. I believe that this is set to CPU by default.

Hi Roland,

Thnx. It is selected and works fine when I start a render from the GUI. It is only when I am using AeRender.exe from the command line that it doesn't work.

There is an unsupported workaround [link], but you could get unexpected behavior if more than one instance of aerender tries to use the GPU at the same time.

I see that you're using the command line render. Such a render, commonly known as 'headless', defaults to using the CPU instead of the GPU. Walter's recommendation is the way to go, to force headless renders to use the GPU.

Thnx Walter. Thank you both for your help.

I'll give it a whirl. I am interested to see if it is only used with raytraced comps or forces all renders to the GPU.

The classic 3D renderer is CPU-only. This setting will only affect raytracing comps.

Hi, I'm trying to get this work around going:
http://www.loopoutcontinue.com/2012/05/faster-raytracing-in-cs6-while-rende...

Need to fix this cuda aerender problem but I can't find the "Debug Database.txt" file? And not sure where the ae pref folder is to create the file if it doesn't exist. Anyone shed some light on this tantalisingly vague tutorial?
