Ello, I've tried to find some info on this, I saw there is a guide to rendering solaris with TOPs, i couldnt get it to work, but also, in the top net context, i couldnt find the same options for husk to go through a COP netowrk for a slap comp.
I also tried using a rop fetch node pointing to my USD render rop in solaris, this partially worked but it didnt render all the geometry in my scene, static geo worked, but crowd sim did not render at all..

Also looking for this...

I found this [youtube.com] wonderful tutorial by Adam, but not sure how to render out with a slap comp, since there is no USD Render ROP. Maybe it is something for Houdini v21?
