Excited to have Curvy3D but need help...

[Cotterpin]

My problem is with inflating images. I've managed to get a grasp on the process, except for one thing. When I bring the image in to be inflated, it inflates but cuts off part of it. I tried scale but that just made the whole thing smaller, but still cut off...

So what am I doing wrong/missing?

Thanks in advance!

Black areas will be cut out - if you want to keep the whole area use dark grey

Also try increasing the size of the original image
