Hammer request: Fading brush

[jmplayer]

I wish for a brush that would fade away as the player approaches it. It would be client side. It's much like func_lod, but it fades as the player gets near.

Some uses:

-Enables multi-story buildings

-Allows fading of the south wall

[CrowbarSka]

I second that, it would be very useful. You could also then make frames over the tops of doors so they don't look so crude.
