change the shape path of a mask

[kauec4902654]

hi

sorry for my english 

i need help! when i create a mask in after effects with pen tool, im not able to modify the path, just the size. 

the shape points are only editable if I add one more. 

I try to double click on the point I want to edit, but open a box to change the size 

i dont want to change the size, i want to change the path

In composition panel, clic with Selection tool in some empty space to unselect the path, then go back to pen tool and clic in a point in the path. Now you can modify all vertice points independently.

The Path must be selected in the Timeline, then the selection tool will change to a white filled arrow as you approach a point or a line. You can drag a selection around points or select a point when you hover over one that is not selected (open square) or a line. Pressing the g key to select the pen tool also gives you access to point editing tools.
