How do I give quicksand an animation?

[DrTapeworm]

I noticed in ACZ that the greyish quicksand in the cave has an animation and I don't know how to get this into my own levels. I need to know this, please.

If I recall correctly, it just does it on its own. Kinda like the water animations. Otherwise, I'unno, and someone else'll have to tell ya.

If you make it a quicksand fof, it will distort the flat for you, making the flat move like in ACZ.

That's what I've been doing, and it doesn't work.

Give the quicksand FOF linedef the EFFECT5 flag, if I recall correctly.
