Using glossyspecular to fake light bouncing
« on: February 20, 2012, 12:19:12 pm »

Using glossyspecular to fake light bouncing is something I've learned not so long ago.

Attached file is pretty self explanatory, but here's a text that describes how it works:

Normally noise removal would be needed. You'll need high AA values - like >=49 and lower RayDepth scene attribute to something less than default: 2-3 for diffuse scenes or 6-7 for scenes containing refractive objects. I thought you might find use for it...

I've already used this technique in two images of mine:

Neat trick though if you have the patience for it!
