Hello guys, I'm scattering animated grass proxies in SOLARIS with an instancer node, in the instancer I have a frame attribute that I need to use when calling for the proxy files (outside the instancer). I'm not sure it's clear so here are some screens :


The stage graph :



So in the grass instancer node I made a point attribute named frames. I'm working with redshift proxies so I bring one in the instancer and after it I need to call the proxy file in the geo render setting.

My goal is to use the frame attribute in the path of the render geometry setting :



And I have the primvar :



But I don't really know how to call the privar and actually it doesn't read it as you can see with the error..

Hope it's possible and someone will know how to do it!
