How do you make an invisible wall in DB?

Hiya.

I am a newbie to Doom Builder.

I'm trying to make an outdoors level, so I set the ceilings to F_SKY but I can't make the outer walls invisible.

Please halp!

EDIT: I'm using Doom2 format!

No responses yet. ;-;

Well, I figured out I could just leave the wall untextured, and it works in ZDoom, but I'm worried this will cause compatibility issues or something with other ports. D:

Someone say something. ;-;

you need to make a thin sector the length of the wall you want to have a 'sky box effect' on and then lower the cieling of the sector to the point you want the wall to cut off. The cieling of that sector should be F_SKY3 (If that name isn't completely correct then I just mean the bog standard sky flat).
Have a look at the outer wall of doom 2 MAP12 'the factory' to see what I mean.

Hope that has answered your question.

Patience is a virtue. ;-)

This thread and taking a closer look at how wrap-around skies are done in Doom 2's Map01 should also help.

This is a general editing question and hardly has anything to do with Doom Builder specifically. I'm moving this to the right forum, maybe you have more luck there.

Tell us or show us exactly what you mean. It would look strange to just have the ground end abruptly into nothingness, so theres usually a wall a few feet high before the sky starts.

Here's an example:

It's a lot easier in Hexen format with the ability to create line horizons, but whatever.

Thanks guys! I finally figured it out using that example.

Now can anyone tell me how I can choose which sky texture to use? Sorry. Last question, I swear. >.<

Use F_SKY1, the game engine will replace that with whichever sky is appropriate for the map number.
