View Full Version : FG renders no diffuse

12 December 2008, 01:59 PM
Hi, I'm working on an outside scene with a HDR (spherical) enviroment map. Final Gather is set to on but strangely it won't render the diffuse part.

Here is a screengrab from a test setup. No HDR map here but that shouldn't matter.
The sphere doesn't have any reflection but does have a diffuse valeu (purple), the radiance is set to 1. As you can see, Final Gather is set to 'on' in the region render. There is no light in the scene, but normal light DO render the diffuse part.
Why does it render the sphere black? Am I over looking something?

Up until version-7 , you needed to have a light in the scene for Final Gather to work. The intensity could be turned down to "0", but a light had to be present.

Since Ver-7 you don't need any light for FG to work.
