I have a solver, inside I have a bunch of different groups going into a switch driven by a random value, which then goes to a polyextrude - the idea being that each iteration of the solver, the switch randomly selects a group which is then extruded, and the geo grows accordingly.

What I want is to reference the name (i.e the string) of the selected group being randomly output each frame by the switch, and fill that into the Group input of my polyextrude.

Is there a way to do this?

Thanks

if the groups are all behind the same switch, can you give all the groups the same name? Then the switch will pick which group to use, but the polyextrude can use a fixed value for the group, but the geometry extruded will depend on the switch.

Or am I misunderstanding your intent?

Are you able to post a scene file?
