So I am experimenting with G’MIC Inpaint[patch-based]
From my experiment:
Patch size - size of tiles(patch) that will be paste on the mask. I found this out when increase patch size to very high value which give blocky result.
Lookup - distance that it will gather texture
Blend - apply a bit of blur to blend in better
Lookup factor - ???
What does it do?? I only know that it does magic.
As you can see in the Lookup factor of 0.1 the cloud have the shape of the pole, while 0.5 is more natural.

Patch size 25, Lookup 10, Lookup factor 0.1
Patch size 25, Lookup 10, Lookup factor 0.5
