The mesh editor extends corner-pin mapping to a grid of draggable points for curved surfaces

The mesh editor lets you map onto curved or complex surfaces that four corner handles cannot fit. Open it from the active tab, first reset or choose a grid size (e.g. 3×3 = 9 control points), and drag control points to distort the texture; ‘show ctrl matrix’ overlays the grid on the output for precise alignment. Closing the editor saves the mesh, and mesh settings are stored with the layer in each preset. Conceptually it is corner-pin with more points: the more subdivisions, the more organic a shape (column, curved wall) you can wrap the image around.

Examples

To map a video onto a cylinder, set a mesh (e.g. 5×3) and pull the middle columns forward to follow the cylinder’s curvature.

Assessment

When would you choose the mesh editor over the four corner handles? Set up a 3×3 mesh and describe what a corner control point versus a centre control point does.

“VPT 7 has an easy to use mesh editor, available in the active tab. Click on the mesh button to open the mesh editor, and you will see an interface not too different from the mask editor.”
