Hi everyone,

The H22 announcements mentioned something about MCP support to APEX Script, and I'm really interested in trying it out.

I'm having a hard time finding any information about where and how this can currently be accessed.

Is the APEX MCP integration already available somewhere in the Houdini 22 builds, or is it currently limited to an internal / private preview?

If it is available for testing, where can I find it, and what is the recommended way to set it up?

I'd also be interested to know whether there are any plans to make the MCP server itself publicly available, for example as part of Houdini or through a SideFX repository.

Thanks!

Every time I open the Snapshot Viewer (Render Gallery), the comparison slider defaults to the middle or the left side of the timeline. Since new snapshots always get added to the right, this means every single time I want to compare my latest renders, I have to manually drag the slider all the way over to the right first.

It's a small thing, but it adds up to a genuinely annoying bit of friction on a tool that's supposed to make quick visual comparison easy. Comparing renders should be one click, not "open gallery, drag slider, then actually compare."

Suggestion: default the slider position to the most recently added snapshot(s) when the gallery is opened, or at least remember the last slider position between sessions.

Anyone else run into this? Is there a hidden preference for this I'm missing, or is this just how it's always behaved? Would love if this got fixed in a future build.

I’m running Houdini 22 on Pop!_OS with the NVIDIA 580 driver branch and OpenCL works fine here.

Since Houdini starts for you when forcing HOUDINI_OCL_DEVICETYPE=CPU, I’d strongly suspect the NVIDIA/OpenCL side, especially since you’re on 610.57.04.

I’d try rolling back to the 580 branch first. That’s also the branch SideFX currently recommends for Houdini 22 on Linux.
