Boom sky transfer

[Thelokk]

So, in my latest project I've been mapping Boom format instead of UDMF, for compatibility, but mostly just to broaden my horizons a bit. 

 

Sky transfers.

 

I searched YT, I searched DW, I even opened other people's maps to study them, and still I can't figure them out. How the heck do they work? I mean, what texture goes where in the control sector, and in the target sector? on which linedefs I have to tag the appropriate line action? if anyone has a tutorial, or a clear example I'd be very grateful, 'cause it's the one Boom thing I simply cannot wrap my head around - I tried everything, and all I get is big fat HoMs.

It is actually MBF sky transfer that just basically works in many non-MBF ports or complevels for the sake of convenience. Anyway,

 

1. Create a dummy sector somewhere in the void.

2. Choose one of its linedefs (any will do) and set the action 271 or 272 on it. The tag of this line will apply the sky to the sectors with the same tag (that also have the F_SKY1 flat applied to them).

3. Set the desired sky texture as the Upper texture of the same linedef.

 

And you're done.

Aaaand this is why I can't figure out stuff on my own, see? still wading in the formats quagmire. Thanks for the explanation!
