1. I have an area light on the left, and a point light on the right.
Raytrace Shadows for the area light is turned on.
It was rendered with raytracing turned on as well.
What I get is a patch of noisy shadow cast by the ball. How is it that I can make it more natural?
(I have the spot light throw a shadow and it doesn't have the noisy shadow. )
2. Since the area light & point light are shining from behind the wooden ball, how come there's still light that got inside the ball?
3. On the surface of the wooden ball, there's actually a separate surface with a material to simulate glass. It's just a plain surface. I want to create depth to it so that when I shin e the light at it, it can show some refractions of the inner wood. How should I go about increasing the thickness of the glass?
