Hello,

I'm building a MtlX Material to be used "cross-render" in Karma, Arnold and probably any other engine that utilized MaterialX.

Cannot make Arnold to use second uv set (uv2).
I have connected mtlx_geom_prop_value node to texcord in mtlx_image node.
If i type "uv" in Geomprop string then its picking up the first UV, but if i type uv2 it doesn't.

Is it a bug or should i use some different node instead?

Houdini 21.0.631
H2A 6.4.6.0 (Arnold 7.4.5.0)

Oh. I got it working by setting geompropvalue to v3 instead of v2. and then by separating 3 vectors and combining 2.
