im trying to export pflow data so i can get the particle system working the same as in max in my 3D engine. i've looked over the pflow source and the source for the gravity modifier, but what ever i try i cannot get my system to look like it does in max. my particle has a velocity value which i multiply by delta time each frame like so: particle->pos += particle->vel * deltaTime ive got particle speed working like so: particle->vel = direction * speed where direction and speed are raw values from pflow now gravity is the troublesome part: direction = nodePos - particle->pos dist = length(direction) direction = normalize(direction) if (decay != 0) strength *= exp(decay * dist) particle->vel += direction * deltaTime * strength * influence where influence = 10 thats 10,000% as in the pflow force influence dialog box strength and decay are the raw values from max any ideas whats wrong?
