I'm interested in creating my own custom crowd trigger node as the current node is somewhat limited in options. I know I can use the VEX mode to get more detailed, but I was hoping to setup something like the pop vop but for setting triggers. In the manual it says: "A user-defined asset can also be used as a trigger if it has a triggerattrib parameter specifying the name of the point attribute that contains its trigger value." But when I setup this parameter, it still doesn't seem to work, with the error "cant find trigger name" Any ideas?

Thanks, Karl

Just use VEX mode. All you have to do is set i@trigger on the point.
// setting i@trigger to 1 will enable
// setting i@trigger to 0 will disable
i@trigger = -1;

While it is true I could just use the VEX mode, I see in the manual that there is a way to make your own. So now I want to! A common frustration with the Houdini manual, I'm sure.

Can you attach an example of your HDA? This approach should work for letting a custom HDA act as a trigger
