OctaneRender 2026.1.Alpha 3 for Houdini Alpha (2026.1.Alpha_3.2)

MacOS version?

Currently the octane core alpha for this is only released for windows - I believe they are still working out things for the mac version, thus no plugin for mac. As soon as core releases a macos version we will also release one!

MtlX Facing Ratio - *** OCTANE API ERROR: No matching configuration found
MtlX Geometry Color - *** OCTANE API ERROR: Can't read string from static pin 'unknown' (P_UNKNOWN, type PT_UNKNOWN) of node '' (NT_UNKNOWN, 00007FFC71E26520)

Will look into this! Thanks!
For the geometry color, did you have the attributes set on the object parameters? This is something that is still required.

Reading attributes works just fine with the MtlX Geometry Property Value node and octane nodes.

May I ask to make the "Zoom Perspective" icon sticky in the IPR like "Disable DOF? Because it gets reset every time I reload IPR or press "Reset Perspective", it gets tiring clicking on it every time I wanna zoom in.

This is not a bad idea. Will recommend it.
