Lighting

After Steve mentioned photon mapping I went on to inspect the original files.He is right there is photon mapping involved the project contains exposure filter(gamma corrector),photon mapping,soft shadows and ambient occlusion(opposed to monte carlo*I think this is used in anim8or) and finally the sphere have caustics enabled.

ENSONIQ5:
Cool, Anim8or can handle Ambient Occlusion via scene attributes and to be honest I totally forgot about that! It would have improved the output though using soft shadows and fiddling with light range/angle settings does go some way towards a similar effect.  I wasn't able to get anything like the original image with a single light source (which I presume the original image used, apart from some ambient lighting) but that may have a lot to do with the materials and how they interact with the light.  So my image is really a 'cheat' that uses a bunch of lights including one to fake the sphere's caustics.

But then your cheat totally works great. 8) After all for someone who isn't into physics and all this 3d development stuff would still accept the image as closest to real life lighting behavior especially if they did not see the original render first.Great stuff man

Perhaps Steve can point us to the AO feature.AO is quiet interesting if you ask me.I have seen some impressive stuff happen when I rendered with AO enabled. In some conditions it almost looks close to (Subsurface scattering * Very interesting stuff,would dramatically make scenes more appealing)
