My six year old an I are having fun experimenting with the Carrara 3 demo. I created a "sun" for him last night using a sphere primative and then applying the sun texture to it. We then added a bulb to the scene with a lens flare and glow effect top simulate a bright sun. Putting the bulb inside the sun sphere hides the bright glowing effect so my son wants to know, tonight, what property of the "sun" sphere do we have to set to make the bulb effect shine through the inside surface and light up the scene? Thanks! David (a soon to be Carrara owner, based on what I've been able to demo)
