Sorry for the title, I'm just getting desperate now.

I'm trying to access point attributes and feed them to a principled shader… nothing too fancy. I just want to plug Cd into the basecolor, or better yet be able to perform math on (eg.) age and life, feed them into a ramp, and plug that into the basecolor.

Unfortunately, using a parameter to call on the attribute just returns a zero… I've searched the web and tried everything I came across, but to no avail.

I'm using Houdini Version 18.0.287. Any help is appreciated. Thanks!

I managed to figure out hot to get the Cd to basecolor working while this post was being approved… there was a packed geometry getting in the way. If I disable the pack node, then the “Use Point Color” option and the VOP operators work. If the pack node is on, then “Use Packed Color” works for a direct transfer of Cd attributes to basecolor, but the operators in the material network don't seem to work. I'm new to this, so I'll keep plugging away for a solution as I'd like to keep the Pack node.
