by the way the demo01 project uses stencil shadows, and the car demo uses texture shadows. if you look close in the car demo, the shadow is also being projected on the ceiling , an afterproduct of using texture shadows. if I broke up the world into 2 pieces (ground+walls / ceiling), I could fix it. but the game I'm planning on making will be outdoors anyway, so... eh.
[edit] I'm not sure about the km/h thing, I must be calculating it wrong. I'm taking the rigid body's velocity (should be in m/s as my units are in meters), and multiplying by (1000/360) which should give me km/h right?
m * 1000 = km, s * 60 * 60 = hrs...
oh wait, I think I could just be multiplying by 3.6, according to an online converter I'll fix it.
