A question regarding skies

[Kassman]

I just wanted to ask what the easiest method to draw a sky on a wall or a pillar would be. I am aware of the vanilla method, and for my current project I want to avoid using that if possible. I am also aware of the line horizon special, although I suspect that it may look strange when applying it on pillars raised from the floor or lowered to the ceiling.

Essentially I am asking if it is possible to apply a sky-like effect to a wall the way you would apply any other texture.

For example:



I want to paint over the buildings in this screenshot with a gradient like texture that follows the player's eyes whenever they move, kind of like what I did with the bridge. (Also yes, this is a gzdoom screenshot, hence the hi-res sky graphic.)

If I understood you correctly, You want the lower and upper textures to looks as if they're invisible and show the sky texture? I'm not sure if this is possible in GZdoom. In software, not having a lower/upper texture where the floor/ceiling (respectively) uses the F_Sky1 texture will render the sky all the way through the lower/upper texture. I don't think this works in Open GL, since missing lower and upper textures just become invisible. There is "Camera Texture" although I don't think that would work for what you want.

A generic UDMF "treat upper/lower/middle linedef as sky" flag would be useful as hell, I think. There's still no way to properly apply Doom's standard "skyportal" effect to lower textures.

For now, you can have F_SKY1 as the floor and ceiling textures immediately around the columns and use [wiki]Line_Horizon[/wiki] on the linedefs.

EDIT: Tested it; it looks fine. Just use a discrete border.

Thanks guys! I will try working on this issue more when I come back from Philadelphia.
