erasing walls

[Wil]

so i'm trying my hand at doom builder 2, and i can't figure out how to make walls disappear (e.g. places where you can fall and die or look at my skybox that i have feeble grasp on using), i notice in mrx that those parts are just gone but whenever i make a sector, it's always square with 4 walls

[Max]

If you draw another sector corresponding with the one you've already drawn there will be no wall between them

[Wil]

i dont know what you mean

[Max]

Do you want a walkable area surrounded by death?

[Wil]

I want an outside section like in hard man's stage

[Max]

Well draw the outside first and put the inside inside it.

[Wil]

draw the outside?

[Korby]

Lower/raise the ceiling/floor in the surrounding sectors.

[Max]

Do a big box to put your map in and make the outside box your skybox

[Wil]

yeah i've got a little grasp on skyboxes

also the map won't boot in the game, it says WIL01 cannot be found, how do i fix this

[Max]

Add it with custom parameters

[Wil]

is F_SKY1 changed to the skybox texture?

[Korby]

I think so.

[Wil]

how do you do this

[Max]

*facepalm*

copy an official map, see how it's done
