What I'm really trying to do, is get the 3d point of the mouse, once it hits the terrain. (atm I'm moving the brush with ASDW :()
The following code sort of works, but it's "lagging", even though the FPS is still 1000+.
The reason: Seems like it "dropping" results most of the times, and only picks on certain places of the terrain mesh?
Also, why doesn't it return the geometry object picked?
Thanks in advance.
