Yeah, I RTFM :-), but the FM was a bit short on that theme.

By chance I discovered the existence of the P Node and what it does (kudos to Castle Poser), and immediately had 239 ideas to milk it for teh lulz. But before teh lulz comes teh work (sigh). And what is very unintuitive to me (save for all the rest of Poser :-) is how the nodes are passing the values to the upnode, because the upnode has a pre-set too. For example, say the P Node is set to x=0 y=0 z=-1 and plugged into the transparency node set to t=0.5, and my pixel is at X=1 Y=1 Z=-2. What transparency has the pixel? z-Z or Z-z or t(Z-z) or t+Z-z or...The possibilities are endless. This holds even for such a innocuous thing like an Math:Add node - you don't have two inputs A and B and an output C=A+B, no, sirre, you have two surplus parameter dials on A and B. (And I didn't even began to ask how colors are piped upstream... :-)

So I would be very indebted for any link to a better, more voluminous FM.
