thanks for the help
but i’m trying to understand the work of the mask control vertices and find a simple way to controlling them with expressions
and what exactly i need it s the reference of the expression that control the bounding box top.left …
because when i make Alt+click in the mask path it s given me
mask(“Mask 1”).maskPath
and i m serching the deep expression that control the bounding box in the standard way
