Thanks for your analysis. I now managed to circumvent the problem
by stitching first the 8mm exposures and then the 18mm ones to
finally blend the two subpanoramas into one. This is a cumbersome
process, though, and it would be much easier if the stitching
process could honour stacks if they are present and only do it's
undocumented hardcoded 70% trick when run in the 'exposure fusion
from stacks from arbitrary arrangement' mode.
The 'any arrangement' mode doesn't assemble stacks, it blends each
exposure level into a separate layer, then fuses them together as a
final step - i.e. it is suitable when you have shot at different
exposures, want to exposure fuse them, but don't necessarily have
a series of 'stacks'.
The current behaviour is misleading, since a user who has assigned
stacks will expect that an 'exposure fusion from stacks' will in
fact fuse these stacks, and not some stacks the program makes up
itself.
Hugin will fuse these stacks that have been manually assigned. The
problem is that it gives no indication what it is doing, and then
people assume it is doing something else altogether...
Actually the automatic detection of overlap for stacks works very
well, it was relatively recently implemented and replaced a much
cruder overlap test (which nobody ever complained about either).
I think your incredibly corner-case example (shooting bracketed at
two different resolutions) is something that would be better served
if Hugin showed what it planned to do, giving you a chance to do
something about it. Disabling a functionality that works fine for
nearly all predicatable situations wouldn't be a step forward here.
