Is there any entity in TF2 that will block the showing of particles, or something that will limit the range of a particle effect? I've used the drip effect from Sawmill which is dripping from a pipe of mine into water, but the drips continue down underwater all the way to the floor. You're able to swim around in the water, so it looks kind of odd that there are water drips underwater. Then again, it might just be that I need to create some sort of control point for the particle effect. I'll look in the particle editor, and knowing me I'll find the answer five seconds after I've posted this.
