Today I learned (found) a solution to the ever annoying edit box disappearing…
How often have you enabled edit box while rotoing something, then you briefly adjust a point individually, the ‘edit box’ is still enabled but has disappeared. So you click edit box twice to turn it off and then back on…
The cool thing about edit box is that can apply to a subset of the vertices, you can always ctrl-drag to select a few and use the edit box on that.
But what happens when you adjust an individual point, the edit box looses a multi-point context and is not displayed, even though you remain in edit box mode.
The way back is to hit Ctrl-A to select all points of the mask, and the edit box is right back where you left it.
(also re-learned to use the mask inputs of the comp node w/o F/B to get access to all the composition modes of masks - other examples out there use F/B for masks, but you lose the composition modes)
