Mask issue (mask is small while processing and the bigger....)

[cyrilp]

Hi i have an issue with mask generation.

I try to make masks but when i select only one picture, i see the mask area being big or small depending on the defocus value while the mask is being generated but at the end when it's over, the mask get smaller leaving lot of unfocus area not masked.

don't know if it's clear...

it's the same if i select "current" or "selection".

What's happening?

Hello Cyril,

Seems like you are observing the same effect that has been reported before:

If you are generating masks using Python, then you need to disable fix_coverage option, as otherwise masked area will be smaller as visibility check will be applied and masked parts that are seen from the single image only will be unmasked.
