[HOU-3613] Volumegrid RGB field binding

[Nevoreko]

Hello,

I'm trying to work with the volumegrid shader to use a Cd field as the smoke color, by loading a vdb volume with a "volume" node in LOP, as it doesn't seem to work, I wanted to ask if the "use field as color if the field is 3float" and "remap if the field is a single float" was working under the USD implementation?

Thanks,

Marvin

[EDIT] The field I was trying to use seems to be a vec3 field, which seems to not be supported, I split it into 3 float vector but it still doesn't work
[EDIT2] Importing the volume in SOP and using a SOPImport, makes the Cd binding works, is it a bug?

[Nevoreko]

Bump, if anyone has any idea on what's going on?

Best,
Marvin

Hey Nevoreko ,

We have a fix under review; I will hopefully ping you in a couple of days when it's available in the nightly builds.

Best regards!
