40. I hope I'm just having a brain cramp on this one. IBLs are directional. I dunno if they didn't used to be, or the just were SUPPOSED to be non-directional, but in P7 the position of the light source changes the way the "global" lighting is applied. After discovering this about IBLs I created myself, I went back to t he prepackaged ones, and this does not seem to be true of them, only the ones we create.

I was working with a Key spot, a Fill spot, and an Infinite, plus an IBL. With everything off except the IBL, and the IBL at -90x, 0,0, the model was illuminated from above. With the IBL at 0,0,0, she's illuminated from the front. It's possible that the problem is, it's not really turning off the Infinite light, but I'm running the Render now with all lights deleted except the IBL....  With them deleted, it doesn't happen.

It's possible that the problem is really the chaotic selection effects. At one point, I switched from Properties to Parameters and modified the XYZ coords, then switched back to Properties and discovered that it had switched from Light 2 to Light 3 without my telling it to. I had modified the wrong light.

41. Because it's so awful, I'll say it again: The selectors are utterly chaotic. A few minutes ago, I had Syd's rToe on the Object menu and red outlined, but the selection on the Parameter Palette was her Left Foot, and the controls visible for the "Left Foot" were for a Light. I had to restart to get rid of the Light Controls.
