In After Effects, when using pen tool, it is missing the Bizier handle.
Any help appreciated.
Do you have the keyframe in question highlighted? Do you have AE preferences set to show handles & paths?
My first guess is that you've set the mask path to RotoBezier. To confirm select the pen tool (g key) and then hold down the Alt/Option key as you hover over a vertex. The pointer will change to the Convert Vertex tool and when you click an drag you will change he tension on the vertex.
If that is the case and you want to go back to standard Bezier adjustments select the mask path by changing to the direct selection tool (v) then double clicking on a vertex. Simply right click on he layer and select Mask Shape and Path and uncheck RotoBezier.
yes, that was it. I simply unchecked Rotobezier and they all came back. Thanks.
