Probably not much help to anyone, but the only times I've encountered
blacked-out sections were:
1. When I was getting too intricate with inclusion and exclusion masks.
They were particularly problematic when close to each other.
2. When masks on different images overlap.
3. When watching a stitch run, the log would report a picture not being
blended. The blend would go fine, I'd note the stitch log's message
about the photo not being part of the set, or being a duplicate, and
remove the seeming duplicate. Then I would sometimes get a blacked out
section. It makes me think sometimes enblend isn't entirely correct when
it reports *not* blending an image.
This is all with enblend. I've never tried multiblend or felt any need
to use it.
I use Linux, so can't help if it's Windows-specific.
