[away3d] position objects on ground

[andrew barry]

IN away 3D how do you position objects in 3D space so I have a plane
(ground) and objects sit on the ground.
Is there an easy way to do this?


The plane does not seem to position itself at the Y-value given as a
variation on Y value about about 50 looks the same. Models of
different heights are tricky to set at the same bottom point.

plane = new Plane({material:mygrass, name:"plane", z:
200,y:-140,x:-100, width:1000, height:1000, pushback:true});
