Hi community, I’m stuck on something I know is simple, but I’m really rusty with Houdini. I want to create an effect where a point rotates—and with it the circle I want to instance to create a tunnel effect—but I can’t manage to assign a rotation value to the point. I attach what i got and what i want to create.

you can create p@orient attribute
there is many ways to create one with the values you want, but since you seem to be using POPnet, the easiest for you may be to use POP Spin DOP inside, which allows you to define rotation speed about a certain axis
