Sorry if these are really stupid, but I can't see either addressed in the manual (which may mean it's under my nose and I'm missing it) 1. When calculating cloth dynamics, what is the meaning of the number that appears in the screen (not the frame number - the other one, with the decimal places. 2. I've come across references to volumetric lighting in P5 - but can't find any reference in the book, or anything immediatly obvious in the program itself (but note the above warning about my nose). Any help with these, especially the second, would be much appreciated.
