Well, here we go.
It seems the problem is BasicRays startpoint, or a brainbug in my head.
Accurate picking works fine, as long i dont change startpoints X and Z (both values have to be 0).
Change i.e "start" X value to 200 and see what happens.
Someone mentioned that a plane doesnt work for Newtons TreeCollision, but plane showed same behaviour as the cube i created for that example.
My cubes mesh scale is aprox. 150,10,150.
And yes, i couldnt find out how a codebox works here:D
