Crushers in UDMF (examples wanted)

[DeathMetalAccountant]

So i'm trying to add a crushing ceiling to my UDMF map, based on the info given in the ZDOOM wiki, and it either doesn't work or glitches up and down ridiculously fast. Can anyone suggest examples of UDMF-format maps with various types of crushing ceilings so I can hopefully learn from that?

Thanks.

That's not exactly what I meant but it did help me figure it out. Thanks. ;)
