Moonray 1.7.0 MacOS Metal Support

[jujoje]

Hi,

Built the new version of Moonray on Sonoma, and all went well (the new instructions for getting it going with Houdini were pretty good!).

One thing I'm finding is that the xPU mode appears to be only using the CPU, not the GPU: I've tried rendering the ALAB scene in Houdini, as well as the curve test scene from the command line and neither of them seem to be going to the GPU at all.

Is there anything additional I have to do? The previous version seemed to work with Metal out of the box (the curve scene was using about 75% of the GPU iirc).

Cheers,

Julian

Hi Julian,

First, so we can check, are you running explicit xpu mode, like this?

moonray_gui -exec_mode xpu -info -in curves.rdla

We've built 1.7 on Sonoma and can see the GPU access also at about 75% on that curves test scene when run in xpu mode. It should also be working for you, if you could confirm. If not, we should investigate further.

Hope this helps! Let us know, thanks.

Hi Randy,

Thanks for the reply!

Tried the curve scene with those options and it looks like it is actually using the GPU; from the logs it is detecting it find and using it for the render. However it looks like it's only using 15-20% of GPU (at least according to Activity Monitor).

SLso I just double checked the machine I was running this on and looks it had been updated to Sequoia (15.1.1). Wonder if it might be down the OS update; 1.6 worked fine on Sonoma. (other than that it was a Mac Studio Ultra M2)
