George, If you go here...
I actually did something similar (alien head) to what you are doing.
One thing I noticed is that ANY time you make an adjustment to lighting settings, you have to do a CTRL-Q to get it to update.
Also, whenenver you are dealing with transparent objects, it's always a good idea to enable "Transparent" under your Global Shadow Control and do a test rendering to see if things improve. If you don't have any transparent objects, don't enable it because it could slow things down with no difference in the final image.
One thing that I find strange is that you get different affects if you have the sliders all the way to the left as apposed to having the first slider (Edges) moved one notch to the right.
When you do that, the Edge Quality slider becomes active, so be sure and experiment a little there.
There are so many settings in PW2 and just one *tiny* little adjustment can throw the entire rendering off in a gigantic way! It's so hard to help people without seeing the actual files or a simplified example.
It's almost as if you need to make a decision right at the begining of your rendering project and say OK, I'm going to use the following settings for example...
Indirect Illumination Spherical Room Reflective Walls with a specific material set to "Constant" No Fog lights Shadows set to "Transparent" with "Edge Quality" active "Number of Reflections" set to "8" "Numer of Refreactions" set to "4" These types of lights and this many Shadow/Fog enabled or disabled for each light Etc etc.
It's settings like these that, if not set early, can cause you to start from scratch all over again.
Other settings like Anti-aliasing Quality, Room size, Shadow softness can be adjusted any time without dramatically changing things.
Well I hope there's some usefull tips there!
