I have some questions concerning the use of area lights for raytracing.

1. It seems that the area samples driving the light and shadow quality (raytraced shadows). Is there a way to decouple light samples and shadow samples?

2. Is there an easy solution to get the shadow a color tint rather to just control the shadow intensity?

Thanks

From a lighting point of view your shadow intensity should always be 1 . If your shadows are to dark and need tint then add fill lights in your scene.

Not other then custom shadow shader.

So, how would I be setup this light with a custom shadow shader?

by adding “shop_shadowpath” parameter to this light. This allows you yo apply your shader to a light.

In the surface shader you can “cheat” it by testing isshadowray() and set Of to be 1-yourShadowColor if true.

If I understand it correctly I have to go inside my surface shader of my object which cast the shadow?

But that would mean if I have 2 area lights and one surface shader I only have the control for “one” shadow.

Can you give me an example?

Thanks

Aren't the occluded objects becoming semi-transparent?
