Description

i think to improve workflow efficiency, i have some suggestion some idea, like adding copy selected vertex from artmesh to other artmesh, it's also make flexibility for mantaining the vertices by copy it, like on cubism, and also features edits multiple mesh to edit same area with complex multiple artmesh with separated shadow, lights, texture overlay, etc it will faster to work in and also extending working capability, and the last one is multi select properties for faster clipping, bcs im a bit confused what is mask node used for, composite node also a changing the entire layer blending and sometimes its change even the z order while used as group for clipping multiple artmesh, soo i think multi selectable artmesh can apply the mask to all selected node for faster clipping

Suggested solution

• Adding capability to copy vertices from other mesh
• Multiple Artmesh editing
• Make artmesh can apply mask/clipping to multiple selected nodes at once
