If a series of source images located along the border between the Left_Layer and thr Right_Layer is duplicated in both layers (reuse of the very same source image is something APG can handle, I use that to test 360x180 patterns using a single source image!) the seam between left and right "half-panos" should not be a problem when stitching them in the final (non Autopano) step. The only reason to limit the process to a single cut operation is related to the seam (see below.)

Stitching "partial panos" using PTstitcher and a very slow PC then stitching the final result using PS is something I did years ago: it worked very well and, provided some source images were borrowed from the part being on the left and/or the right part, no seam was visible.

This could look like a very biased trick, but when the amount of computing power you need grow faster than the size of the resulting pano, this is the way to go. Under the name of "parallel stitching" this could look more glorious (une sorte de vengeance du soft sur le hard :lol:)

Note: as PTstitcher was stitching more and more empty pixels when the number of source images was growing, the difference when using this splitting method was really dramatic. Autopano don't stitch empty pixels so that the above is, almost in theory, only useful if it can improve working-sets management during the render step. BTW, the later gigabyte size and 300,000 pixels wide PSB files are created the better.
