You should use the fastest build, it’s way faster on booleans ^^
I don’t have any MacOS computer, so I cannot test, sorry.
I will try to put a default detail size.
Little Timelapse on speeedSculpt by Max Maurel !
This is nice to see how people work !
On this video I see that on skin, I have to make a separate by loose part before making the boolean union.
On the Bsurface, the line must be on the same direction to work.
‘Create Curve’ -> you make a curve with ‘stay in curve mode’ checked -> you’v got 3 sliders (Bevel, Offset, Depth). If Bevel slider go to 0.000 then Bevel/Offset/Depth sliders dont affect that curve anymore. I solve that deleting that curve and creating a new one and avoiding 0.000 for the Bevel slider.
-‘Extract Mask’ is a bit confusing when ‘Go to Sculpt’ is checked (regardless of the check on ‘apply Solidify’):
I suggest to replace ‘Go To Sculpt’ with ‘Go To Edit Mode’. Why?
First thing: In Edit mode the ‘thickness’ and ‘offset’ sliders turn ‘invisible’ (but they turn visible again when you return to Object mode). That’s a good thing because is the expected & right behaviour (the extracted mesh can be affected by a modifier’s sliders only in Object mode) . But if ‘Go to Sculpt’ is checked these two slider remain visible, but they cant affect the extracted mesh if you toying with them (because you must be in Object mode). The ‘apply Solidify’ is checked but when “go to Sculpt” is checked too then ‘solidify modifier’ is not applied. These behaviours build up confusion for blender newbies.
Maybe a button like “click me and you go to Object mode to make those slider affect the mesh again” from Sculpt mode will make the trick?
Second thing: ‘Go To Edit Mode’ instead of ‘Go to Sculpt’ because in Edit mode you can directly use the Extract Mask like a mesh just create with ‘Create GP Lines’ (try that to see what I mean) , and enabling ‘snap to’ and ‘proportional editing’ is a nice addition too while editing that extracted mesh.
A reminder: ‘add bsurface’ button from ‘Create GP lines’ is visible only if ‘Bsurface GPL Edition’ addon is installed. That addon is already present in Blender addons package.
