Thanks The sound effect hasn't changed. For some reason it just comes out better in the video. I do plan to have a better explosion sound effect in the next update, though.It depends. The lighting is all calculated in tangent space (matTangent doesn't appear to work with sprites, but the fact that the sprite always faces the camera works to my advantage). The depth output is modified to make the sprite clip like a sphere (affected by the noise, of course). The explosion moves quite quickly, so as long as the camera isn't rotating while time is slow/frozen, it'll work. jcl said we'd have 3D texture support soon, and once that happens I can overcome that hurdle as well But yes, until then, they are relatively limited.
