I apologize for the DAZ 101 type question, but here goes anyway. If there's a better place, mods please feel free to move it. I'm following one of the tutorials in the DAZ manual, about lighting. It says to click on the button to turn shadows on. I don't seem to have that button. I have a button to turn illumination on or off. But regarding shadows, all I see is a button that can set the shadows to "none", "deep shadow map" or "raytraced". Can someone tell me what those options mean/do and which is best to use in which situations? Thanks in advance Jayne
