I'm getting right (insert swear words here) with Python today. I've managed to get a nice little script that selects each light in turn, but I can't work out how to have it set the ray trace shadows option. here's the script I have so far import poser scene=poser.Scene() lights=scene.Lights() for light in lights: actor = scene.Actor(light.Name()) scene.SelectActor(actor) scene.SetRayTraceShadows() doesn't work, what am I doing wrong?
