Hi, Im in the process of creating my own head, and am now at the point of projecting my photo referannce images onto the front and side.
I did the front first and that worked fine, but when I came to do the side projection the image is now crooked on the geometry (see image). Ive used a checker to show the problem more clearly. If the projection was working correctly then the checkers would be straight.

Any tip, help or advice would be greatly appreciated as I am at a total loss.

Thanks
