Hello,

Apologies if my terminolgy is not quite sound, I'm getting there!

I understand that I can create attributes on geo that have the same name as parameters in shaders, such as ‘rough’ and they will override the value in the UI.

But how do I use the same attributes on packed geometry? Just like the standard “Use Packed Color”.

I found on a forum post to use the ‘renderstate’ node.
I also see that that is how ‘packed color’ works when digging into the shaders (attached).
But when I plug in a renderstate with “packed:rough” I don't get a result.

Any ideas?
Thanks
