Is anyone else getting problems with collision and/or a Juddering to the Y position? I'm currently placing object at my camera position when I press a mouse button so you would imaging that if you don't move the camera the objects should all appear at the same position but I'm finding that although the X and Z are fine the Y position of an object can float +100 to -100 approx. Also the collision on these objects is ocassion at best. I'm guessing that that might be because of the Y Problem. I've also tried printing labels/text at the X,Y position of the object every frame and although the objects themself appear static the labels judder.
One last thing is the collision demo with a couple of sliding boxes and a ball bouncing on a tentical which also seems to have problems. The ball sometimes bounces deep into the tentical causing the sound effect to repeat rapidly and one of the boxes now appears in the air. I'm sure they both used to be on the ground.
