Impossible to use GPU with Cycles under Win10 but no problem in Blender

[MattRM2]

Version: Gaffer 1.3.4.0-Win10 x64 Third-party tools: Cycles Third-party modules: nothing

Description

I'm not enable to use my GPU with Cycles but in Blender, no problem at all. I used CUDA:00, also CUDA:01 (my two GPU for rendering). Also Tried OPTIX:00, OPTIX:01, CUDA:0, CUDA:1 and nothing, still errors. In my computer I have 3 GPU, a GTX 970 for display only and two GTX 1070 TI for rendering. No problem at all in Blender in CUDA or OPTIX mode.

Could you help me please ? In attachment, two screenshot of the error and the setup. If you need more, tell me.

Thank you,

Matt

Steps to reproduce

1. Just used CUDA:00 in the Cycles options / session / Device(s) / CUDA:00 like explained in the documentation.

We don't enable GPU support in the official GafferHQ builds of Cycles, as we haven't set up the necessary build infrastructure yet. But you might have some luck with @boberfly's unofficial releases, which do include GPU support.

Hi, Ok, I understand now ;) Thank you, I'll try it now. Do you plain to include GPU support in the official released in the future ? Or is it possible to build it from your git data ?

Thank you again for your answers.

We'd like to - it's mainly a case of sorting out a Docker build container with the appropriate CUDA and Optix bits. We're eyeing up the ASWF containers which seem to provide this, with there being a small possibility we'll get there for Gaffer 1.4.

Or is it possible to build it from your git data ?

It is - you'd need to build GafferHQ/dependencies as well though, since that's where we get Cycles from. In the short term, I'd definitely recommend saving yourself the bother and using @boberfly's builds.

Hi,

Sorry for the delay. Ok, thank you for your answers, Have a nice saturday,

Matt

Closing as Gaffer 1.4 introduced support for Cycles GPU rendering with CUDA and Optix devices on Windows and Linux GCC 11 builds.
