finalRender 101: Simple Environment and Object Based GI
Added on: Mon Nov 26 2001
Page: 1 2 

Somewhat smooth. Not too much artifacting evident, but it's hard to tell. I want the image lighter than this. Remember, too, that the amount of light reaching the scene is partially dependant upon the size and placement of windows, etc.

Go back to the Material Editor and increase the Recieve parameters for each Material to 2.0. Render again.

Better. A little artifacting, but that can be fixed later by pumping up the RH Rays and prepass size. If you used high specular and glossiness levels in either of your materials, you'll notice that the GI doesn't bring out highlights on the spheres.

To do that, add another omni and this time turn it on. Under Affect Surfaces uncheck diffuse but leave specular on. Go back to the Final Render Globals dialogue and increase the RH-Rays to 600. Increase the prepass size to 1/2 and render again.

Part two of this tutorial will cover HDRI basics and self-illuminated object based GI.
