Apologies for another newbie question. I'm experimenting with something that will eventually be a quilted airbag for an airship. As a test, I have a shader applied to a spline object that is the airbag. (The shape is simple at the moment but will eventually have some notches for ropes.) As a test, I have a simple texture loaded into both the color and bump channels. The trouble is that the two don't line up. You can sort of tell in the preview window that they are offset. I've ctl-dragged the color channel to the bump channel so I was assuming they'd be treated identically. The shader shown is the basic one but I've also tried various parametric mapping modes without any difference. It seems like the UV space/offsets for the different channels are different but I don't see anyway to adjust this. Hopefully, I'm missing something simple. Thanks for any help, Marc
