Ah I miss Vancouver, sometimes We're apparently in the middle of winter, blue skies, 25 degrees... go figure

FG/GI Freeze, absolutly, if you generate the FG GI at half the final res, freeze and re-render at full res is quicker than FG/GI at full res. Dont go too small though. Although for testing dont bother.

Photon tagret - this has nothing to do with the size of the photons but rather the area where the phtons first hit. Think of it as a tube down which the photons are shot. At the moment the photons are focused on a pin head, and I would hazard a guess that most of the scene is being light by FG rather than the photons.

The exterior daylight is for exteriors, behind the scene mathermatics are adjusted by this toggle. For interiors try physical scale of 1500+. If you have max2008 or higher use mrphotographic exposure instead. Not too sure if Viz2008 has it though

Photon sampling radius controls the detail of the illumination by photons, small radius ->more detail -> more photons, larger radius->smoother/less detail->fewer photons. its a balancing act to find the right numbers

Leave the max reflection/refraction as is, these control how the lighting solution looks in refections and refractions, play with these if you have errors in the reflections/refractions

anyone please correct me if I havn't explained properly

Hi Guys,

My apologies for not posting the amended version of what I've asked you guys to help with. I've managed to tinker with it with all of Justin's recommendations and came up with different appearances. I think I finally found out what's wrong after reading a portion of that book I have. I will post it again soon - just a little bit occupied.

Ky Lane - Let us know if you're in town.

Thanks a lot guys!
