Comments on: Color Occlusion by Spherical Area Lights

I used the basic AO/overcast technique for years (without the fancy colour bounce), before FG and GI was available and in Softimage3D. Nice to be reminded of it. Huge area point lights offset towards the sun’s direction gave some nice results, especially for overcast scenes or fill light. There was a way of using a huge sphere smaller than the area light, textured with a sky dome and using the RGB for transparency, which cast coloured light onto the scene. Area point lights were awesome :) Need to get rid of the dreaded hard jagged shadows on smooth poly objects? Use an area point light thousands of units away. It beat Renderman hands down. Hardly ever used an infinite light.

Them were the days. Thanks for reminding me of it ;)

Hi,
I can’t seem to reproduce the effect above using a point light, but it works with an infinite light. Could u post just a simple readme type instructions? I’m using xsi6 foundation on linux.

TIA
