Ah, I see. Try waiting for the model to be loaded before setting for now, I'll review and see if it can be changed to also work before it is loaded.

On loaded is a trigger, you typically cannot include two triggers in event blocks.
So, in your case above, just create a separate top level event block with 'On loaded and set rotation', then as each is loaded, it will set a random rotation. Remove the 'Is loaded' from the loop.
