Can you make a fake roof in Boom?

[Sinnesloeschen]

I have a large and high sector that simulates "outside" (The black void in the pic). The player comes out through the entrance below the white line.

 

Is it possible to make it seem like the wall above cuts off at the white line while the player can still traverse below it?

 

I played around a lot with linedef 242 (Create fake ceiling and floor) and self-referencing sectors, but never got something worthwhile out of it. Gotta admit though i also only sorta understand how those methods work exactly.

 

 

 

EDIT: I may have figured something out, but it feels weird;

 

I used the "Skyhack" method without the actual sky.

 

BUT this only looked fine and non-glitchy when i removed the ceiling texture. And that feels like i'm doing it wrong and it will cause issues - or is that just a quirk that works? It seemed fine on my end;

You can lower the sky ceiling, the upper texture between two sky ceilings is not drawn. However, you won't be able to see behind it, so it only works if there's nothing to see.

That seems like the way to go but would require the sky texture. The map in question is set at night so i just use a high ceiling with a dark texture.

No, it won't require a sky texture, you just need to lower the ceiling around the building. The sky will be drawn as a sky.

Sky is a texture anyway, but it will look like a painting if applied.

But i don't have "The Sky" - I have a dark texture that doesn't utilize the 'special' properties of F_SKY1.

 

And if i lower the ceiling around a building with that i get HOMs and general glitchyness, like here:

I feel i'm missing something here.

Oh I didn't understand this. In this case yes, you can't have fake roof.

Damn it lol. Still thanks for the info.

 

I did figure something out that works with how i set my map up - But it means having a sector without a ceiling texture, like so:

 

fakeroof1.zip

 

Would a missing ceiling texture cause issues?

 

It's a nice pitch black on my end, which is the desired result.

How do you feel about using custom textures to simulate a 3D space?

Take a look at E1M8, or better still at E1M8b romero's updated version, for typical "roof" structures in original format.

I appreciate the examples, but those use F_SKY1 which i'm not using due to the map being set at night. :p

 

I found something out that works (On my end atleast - see op) but requires an untextured ceiling.

 

So my question now is: "Does a missing ceiling texture cause problems?"

Every modern source port which supports Boom also supports MBF sky transfers, so you could just make a second (pitch black or starry) sky and use that.

That's a good idea, thanks!

 

Haven't actually played around with those linedef actions and they could help a lot.

 

EDIT: Welp, that is definetely a cool feature. Unfortunately, no matter how dark the wall texture, it is a tad noticable. I still get the best result by just having a sector without a ceiling.

 

 

So that question still stands: Does having a sector (In the play area) without a ceiling (texture) cause problems?
