Recently in Sandbox Island Extension I was exploring the physics of spheres and noticed many of the basic rolling functions are not working correctly. 1. Make a 3m sphere then hollow it out and make it physical then drop it on the ground. In many of the sandboxes I tried this the sphere just sticks to the ground and will only slide rather than roll. Should just roll and come slowly to a stop. 2. Try pushing the sphere around like playing soccer and the sphere hardly moves, slides, or starts to roll then falls into the ground. 3. If you play around with grabbing the sphere with the mouse and moving it all over the place while bumping into your avatar all sorts of things happen like throwing your avatar into the air or the ball suddenly just flies away. Strange stuff. I rely heavily on proper physics in SL to do teaching or even team building events so this is messing me up. There are also problems with cylinders too.
