ShapeBlueprint scale

I have a little question on ShapeBlueprint,

you can't have tools like set the scale of your shape directly (in case where you use ConvexShape for instance) ?

Or did somone know about an other way to make it without modify the .mesh file like create an entity modify it and use it to build a shape ?
( in the case of convexShape)

thanks

You can adjust the scale of a convex shape. It's in the ShapeParams under mMeshScale.
