How high should your FG Rays be? I read somewhere that 1000 is a lot, but another tutorial I saw pumped his up to 10,000 for a simple kindergarten-like chair and table scene. 2. There are times when I render and it looks pretty good even without the me adjusting the Min and Max Radius. Do I leave it as is then? Or do I put my own values? When do you adjust the min and max radius? 3. Also if you're rendering large formats, say larger than letter size and 200+ dpi, do you need to increase the FG Rays and min and max values? Please check out my Sword in the Finished Work forum and tell me what you think. Comments and suggestions welcome. Thanks! Calvin

Another thing, how do you measure scene size? Do you measure diagonally from point to point like you do a monitor? A 17" monitor means its 17 inches from the upper right corner to the lower left corner, is it the same with FG? o_O
