I created shapes through a script to control the fingers in my hand...
ControlShape= circle steps:4 wireColor:[0,0,200] thickness:0.5 sides:4 radius:1.4 render_displayRenderMesh:true
After that i manually convert some of the to editable spline and modify them so they have a shape that works best with the mesh of my character.
My problem is that as soon as i either add a modifier Edit Spline or conver them to Editable Spline, they disappear when i select one of them.
Does anybody know what's going on?
