I don't know what I'm doing wrong, this always worked in 16.5. I've made a set of grooms, merged them, added the deform guides and the sim guides, everything seems fine. But when I pipe the groom data into a Generate Hair node it just fails, saying there is no ‘skinprim’ attribute, but….there is. All the grooms going into the node have the attribute. The error says to use a “Guide Skin Attrib Lookup SOP” which I added to the hair gen node with absolutely no effect.

Oddly, it looks like I can connect the hair gen to the guide or guide deform directly without problem, but anything past a ‘groom merge’ is just broken.






Any ideas what I might be doing wrong?

On Houdini 17.0.352, Windows 10.

I have the exact same error in H18.
Did you manage to solve this problem?

Can you make a sample scene and i will take a look. I think i might know whats causing it but i would need to see it.
