THE PLATFORM: iPad Pro M4
NOMAD APP VERSION: 2.12.1
While using the mask lasso tool, only when symmetry is turned on, it creates unwanted mask in other places depending of my view, or the reflection in the other side is incomplete. It also happens with others of the mask shape selection tools… the brush works normally.
No screenshot, no example of what’s wrong.
I will make a video later, it will be clearer that way… but it is pretty obvious to see, unless for some reason only happens to me?
This happens, only with symmetry. The Mask brush behaves correctly.
As suspected: not a bug.
Each shape impacts the other side of the head as well, unless you enable the “front-facing vertex” option in the Filter (stroke) menu.
But the mask appears in random places… both with and without front facing activated… and when it appears in the other side it misses a part according to the point of view. I think the weird behavior is clearly shown in the video… the Mask Brush does work normally unlike in this video.
You cannot compare with the mask dot mode, the dot mode doesn’t go all over the model…
If you have symmetry on (and front-vertex off) a single shape will output 4 patches, it’s not random.
The potential bug is the non-symmetrical result at the 0:10 but I don’t know what the symmetry looks like since you didn’t select the symmetry menu.
It seems to work unpredictably to me and it didn’t use to be like this.
It was always like that, since day one.
I used often the lasso mask and never acted in this way but until 2.9
I am confused. 
Just trying to help.
I am gonna avoid the lasso tool with symmetry then I guess.
Wait for next update (2.13), it’s coming soon anyway.
I missed the bottom bar with the “front” ON. (It’s a “front-vertex” issue, without it it should work fine)
thanks for the app update… I don’t see the mask problems there anymore. Maybe I was just too impatient, it is just than with this new version I am all into nomad sculpt again I can’t help to notice any weird behavior. But the app is ★ ★ ★ ★ ★
