Follow-up: we're able to get around the problem by leveraging a native USD binding mechanism: authoring a preview material and binding it using 'Preview Render' purpose rather than the default 'All' or 'Full Render'. We essentially wind up binding two materials to the object, but with different purposes.

Hi Tim,
I think I ran into the same problem in H22.
Do you have an example scene with this setup?

- it seems to work now - Houdini 22.0.429

The flowmap-visualize works in Houdini 21 using the OpenGL viewport,
but does not appear in the Vulkan viewport.

The same issue also occurs in Houdini 22

is there a workaround ?
