To overlap vertices or corners precisely in Spine, you can use the vertex copy-paste feature. This allows you to copy the position of a vertex from one mesh and paste it onto another, ensuring exact alignment. To do this, select the vertex you want to copy, press CTRL+C, then select the target vertex and press CTRL+V. This method ensures that the vertices are perfectly aligned without affecting their weights. If you want to align corners specifically, you can use a reference image or mesh to guide the placement of your vertices, ensuring they overlap exactly as desired.
