I have a point instancer, inside it are coloured points, outside I instance a box to those points.
-karma CPU and usdpreviewsurface + usdprimvar set to 'displayColor', the colours are there.
-karma CPU and mtlxstandard_surface + mtlxgeomcolor, the colours are there.
-karma XPU with either of the above materials, renders black.
Is there a trick I'm missing? I thought I read somewhere this was meant to work, the xpu page in the docs ( https://www.sidefx.com/docs/houdini/solaris/karma_xpu.html [www.sidefx.com] ) implies this should be supported.
Attached some test renders and a repro hip.
Cheers,
