Forcing Blender to use GPU

[Danny_Austin]

Hi,

I’ve followed the steps here but I’m getting the following error. I believe it’s something to do with the python version but I’m not a programmer. Does anyone know now to resolve this?

(for context, I’m trying to render with Blender 3.6 using GPU on Deadline)

Here’s the error:

By the look of it you’ve got a 10.2 Blender.py running on a 10.3 Worker. If you’re running the steps and files you downloaded from Karpreet’s post here, grab it again. 3 days ago he fixed it up to be 10.3 compatible, so you may just have an out of date file.

And be sure to either restart the Worker or submit a new job after getting the files in place, or else the old application plugin files will get used, and you’ll get the same error.

To be sure you’ve got files in the right spot, once you’re done there should be a DeadlineRepository10\custom\plugins\Blender\Blender.py that looks like this:

Did you have any joy with Mac OS / GPU on Deadline?

is there a way to hard code this path so we don’t have to fill it in every time? Can’t seem to find the line to add it in the script.

You can add it into the line like below, this way it’ll auto fill

    scriptDialog.AddControlToGrid( "AdditionalArgumentsBox", "TextControl", "-P Z:\BlenderForceGPUScript.py", 7, 1, colSpan=2 )

I’m just revisiting this as I’m looking into it for a client. Seems to throw errors and fail this way

"C:\Program Files\Blender Foundation\Blender 4.2\blender.exe"  -b "Z:\tests\blender\simple_3.blend" -t 0 -x 1 -o "Z:\tests\blender\####.png" -s 14 -e 14 -a -P Z:\BlenderForceGPUScript.py

If I move the additional args I still get the errors but the render goes through

"C:\Program Files\Blender Foundation\Blender 4.2\blender.exe"   -P Z:\BlenderForceGPUScript.py -b "Z:\tests\blender\simple_3.blend" -t 0 -x 1 -o "Z:\tests\blender\####.png" -s 14 -e 14 -a

not sure if this is a 4.2 thing, I find I’m having to manually install the submitter now too

so adding the line before the others in Blender.py (Around line 80) throws an error but forces renders on the GPU

        renderArgument += StringUtils.BlankIfEitherIsBlank( " -x 1 -o \"", StringUtils.BlankIfEitherIsBlank( outputFile, "\"" ) )
        renderArgument += self.GetPluginInfoEntryWithDefault("AdditionalArguments", " -P Z:\BlenderForceGPUScript.py")
        renderArgument += " -s " + str(self.GetStartFrame()) + " -e " + str(self.GetEndFrame()) + " -a "
