note that if you do float f = (float)rand(); it will convert the integer into a float (thus 10 will become 10.0). So now if you want to limit the maximum value you can do something like (not sure if this works) int tmp = rand(); float f = *((float*)&tmp); tmp = (unsigned int)f // note float to int conversion! tmp %= max_number; f -= tmp;

It could be that you're not clearing the depth buffer. It doesn't affect any of the particles because you are disabling depth test when you render them, but when you render the plane, depth test is enabled, and since the depth buffer has not been cleared it has a spaz and doesn't render the plane.
