Ah, sorry, my bad.
I guess I'd try the simple approach first by masking the cubic tiles
with roto or soft crops.
See how far you get there, then possibly project patches onto the seams
to cover them up (rendering the unwrapped UV of the seams might help as
a guide).
The Nuke/Mari bridge should help in that you can paint directly on the
models but you will have to lock yourself into a resolution, so it's not
quite non-destructive (which may not matter).

Thanks, Frank. Let me clarify my question a bit.
I was actually asking how to blend two full 6-pack projections, e.g.
the "-Z" map of the 1st cubic-cam setup is overlapping with the "+X"
of the 2nd cubic-cam setup that is 100-foot away from the 1st. How
should I address the overlapped projection?
My current test setup has a huge cylinder to represent an open
exterior space a vehicle passed through. Multiple cubic-cam rigs will
project panos taken on-set say 100-foot apart. The overlapping is all
over the places.
Hope my question make more sense now.

If you shot full spherical you shouldn't have to blend anything,
as the cubic tiles should just match up.
Otherwise you can pre-treat your cubic tiles on texture stage,
i.e. give it an alpha and premult, the shader will over it based
on the order of your projections or the MergeMat settings if you
use that. A crop with soft edges may also be a quick fix.
If you extract the cubic tiles from a latlong first, you could
extract a little more than 90 degrees, project that back
accordingly (i.e. on a larger card with a larger fov), then use
the ScanlineRender node's z-blend feature. But again, if you
extract the tiles from a latlong they should already match up
perfectly.
Does this help at all?

Hi folks,
If I have shot multiple full-spherical panos and want to project
them onto say a big long cylinder that represents the exterior
space a vehicle will pass through. What would be the efficient
way to blend between two adjacent 6-pack cubic projections so the
overlapping area is clean for environment reflection or lighting?
Should I do something through the MergeMat node or render to UV
space and retouch in somewhere else? Or will the Nuke/Mari
integration facilitate this process?
Thanks,
Jason
