This is almost always due to MaterialBindingAPI not being applied to the asset. Try running usdfixbrokenpixarschemas on that USDZ file (make a backup copy first).

I believe I logged it the other day before I saw your reply
I had a quick scan of the bug database and I don't see anything. Do you have a bug ID?
Render Pass lop funcitonality Jan. 14, 2026, 5:19 a.m.
Thanks for pointing that out. Our starting point for applying the Render Pass has been based off of code in the USD repository for RenderMan. That includes, by design, only applying matte data to *geometry* (https://github.com/sideeffects/HoudiniUsdBridge/blob/houdini21.0/src/houdini/custom/RAY/BRAY_HdKarma/BRAY_HdRenderPassSceneIndex.C#L127).
Your suggestion that we should support specifying this at the parent level is sensible, especially given that we support this when using the Render Geometry Settings LOP to set the matte flag.
Can you please log a bug/RFE for this? I won't be able to focus on this today, and I don't trust myself to remember to come back to this otherwise
