RaycastPicker bug

[matrix3d]

why can not pick?

the center of point is x=8 z=8

[gonchar]

thank you for the issue, I will check it soon

[matrix3d]

@gonchar thanks there have 5 mesh,if you marge it to one mesh.the vo also null.
var vo:PickingCollisionVO=raycastPicker.getSceneCollision(new Vector3D(8,1000 , 8),new Vector3D(0,-1,0), scene)

but if set vector3d (8.0001,1000,8.0001)
the vo not null.
