In Houdini, I have set up a collision in the POP sover with a static object node in the POP sover.
When I render the simulated particles, the collision object is also rendered. Is there any other option to hide the collision object when rendering?

Right now I am using groups and blast to erase collision objects, but I think this method is not a good idea.
Thank you in advance for your help.

Go to the Object Merge tab of your POP Net and instead of "*" select the POPobject(s) you want to be rendered.

The "*" in Houdini in general stands for "everything" in this context.

It was very helpful. Thank you very much.
