custom plop sound?

[justinrpg]

I downloaded a few B.A.T.s that when you plop them a third party sound plays that isn't originally in the game... such as the coca cola building... when plopped the "always coca cola" tune plays... what do i need to do to use custom plop sounds in my B.A.T.s I have a few .wav files i want to use as a plop sound

There's only one, very old, tutorial available about custom sounds; this one by Pegasus.

Those two TRK files that Pegasus is referring to have long ago disappeared from that thread.
I'm attaching that original file to this post for you though.

Once you've created your own TRK file, link to its unique IID from the property SFX:Default Plop Sound in the building exemplar.
