Ok, I'll buy that. I'm so used to the total chaos of Poser cameras that I jumped to the wrong conclusion. I've taken a look, and it looks like once you set the cameras to a mm related to the real world, then you have to manually reset the hither and yon for your new camera setting. Whether that would be video card dependent is beyond any hardware expertise I want.

The hosed OpenGL preview is camera dependent, suggesting that this is the explanation. It's also virtually random, suggesting that determining the truth is a matter of luck.

I'm curious, given how hither/yon manage to screw up preview, grouping, and whoknowselse, has anyone actually found this "feature" useful?
