I am trying to build the n-side polygon and I want to use Gizmo Point instead of my simple impact point, to move the gizmo point for editing the polygon, how can I do it? because When I want to use Gizmo then i got an error.
You can only attach a gizmo to a mesh, a transform node, a bone, etc …
If you want to move a vertex with a bone, then you can create a transient transform node, attach it with a gizmo and set the onDrag behavior to modify your vertex based on the transient transform node position.
