3ds Max, glow effect diminishing with distance

[SasoDuck]

I'v been trying to figure out how to do this for a while, and I found a checkbox in the effects panel that says "Distance affects: [] Size []Intensity" but checking those didn't seem to do anything. Is there another thing I should be checking to make this work, or another method to make glow get smaller/weaker the farther away I go? Thanks

I think its a check box called Z Depth.

Is that different from "Affect Z Buffer"? I tried that but nothing happened. Also fiddled around with turning off "Affect Alpha" and turning on "Affect Z Buffer," turning them both on, both off, etc. nada.

so, how can I make this work?
