The Edit Mode allows you to add and adjust vertices of the masks of any selected Surface.

Edit mode works exclusively with Surfaces and not the asset layers within them.

How to edit a Surface

1. Click on one or multiple Surface layers.
   • Mac: Select more than one layer by pressing ⌘ and clicking on an additional layer
   • Windows: Select more than one layer by pressing CTRL and clicking on an additional layer
2. Click on the Edit Icon in the Toolbar or press V.
3. Once surface(s) are selected, their vertices, control points, and edges are available for edit.

Translate

Vertices and edges can be selected and translated. Click on any vertex or edge to edit it. Translate the vertex or edge by moving it in any direction. Shift+Click to add/remove the vertex from the selection set. Drag select to capture multiple vertices.

Add Curvature

⌘/CTRL+Drag on a vertex to add control points to that point, which makes both edges it is attached to into a bezier curve. Click+Drag a control point to edit the location of both control points - the control point that is clicked is freely translated and the opposing control point will move to keep the curve smooth. ALT/option+Drag will allow editing of only the control point clicked, leaving the opposing control point unaffected, which creates a corner in the curve. ⌘/CTRL+Click+Drag a control point to edit the location of both control points and to mimic the translations done to one control point on the opposing control point.

Adding Control Points

⌘/CTRL+Shift+Click on a Path to add a new point on that path where clicked. A point will appear along the path to guide where you'd want to place it.
