I have a very simple test agent: A single body geo plus an optional prop geo


I have an attribute set on all the agents: 'prop_var' which has assigned either a 1 or 0 to all the agents in the Sim.

How would I go about only applying the prop to all agents with an attribute value of 1 for prop_var?

The Crowd Assign Layers SOP is probably what you're looking for, but you'll want to set up a separate agent layer for the prop shape. The 'LayerVariations' helpcard example for Agent Layer should be pretty close to what you're doing
