Switch if prim exists July 6, 2022, 5:40 a.m.

Yes. That works nicely. Code for the test:

if pwd().input(0).stage().GetPrimAtPath("/Render/Products").IsValid():
    return 0
return 1

I'm on Houdini 19.0.383 currently so can't do the activation parameter thing but that looks cool and I'll keep it in mind for when we upgrade our Houdini version.

Thanks. I had a similar thought but you got further with the code than I managed! I'll try this out. I was hoping there would be a simpler way though. Perhaps not.

Switch if prim exists July 5, 2022, 11:55 a.m.

I'm trying to to get a switch in lops to change based on whether a prim exists or not. The aim is to automatically create a beauty rendervar and product if one has not be defined. I can't work out how to set the switch lop up to achieve this though. Basically if "/Render/Products/beauty" exists, 0, else, 1.
