Hi folks!
My first focal blur test..without reading the docs.. I just found the insert
menu! well maybe not, but it sure is useful :)
Questions:
How do I smooth the blur more? Tried to increase blur_samples to 30 but it
didn't help at all..
The focal point goes alle the way on the x-axis, how do I "center" the
focus, cylindral camera?

10x10 Area light (one of my first tests with area lights too, lovely stuff!
:)
Radiosity (taken straight from the insert menu)

1h 20m @ PII 450mhz 256ram win2k POV Beta 16
