Help: custom sky texture tiling

I want to use this awesome blue sky texture by @Fuzzball that is posted here, so I followed these steps:

1. export the sky as rsky1.ppm

2. create wadinfo.txt with the relevant RSKY1 entry, and a textures entry

[patches]
RSKY1
[textures]
TEXTURE1

3. create textures1.txt to define the texture size

;Format of textures:
;TextureName	Width	Height
;*	PatchName	Xoffset	Yoffset
SKY1        		1024	200
*	RSKY1       	0	0
;End

4. use deutex to compile the PWAD: deutex -make custombg.wad

No errors so far, and loading the wad does show the new sky, but it does not seem to be wrapping very well. Can anyone offer some tips? I would prefer using deutex if possible.

I compiled slade3 from source, but don't really know how to use it, and have been struggling to find a good tutorial on custom sky textures for it.

custombg.wad.zip

It should wrap fine- did you import it as 1024 wide?

A patch cannot be wider than 256, so you need to split the image into four 256-wide patches and then build the 1024-wide texture from those patches.

Ah I understand, I will try that in the textures file, thanks @Empyre.

I did indeed, but might be a limitation of the engine as noted above. Thanks for the beautiful textures by the way :)

So I split the sky image into 4 patches of 256x128 and updated wadinfo.txt to include these:

[levels]
MAP01
[patches]
RSKY1
RSKY1B
RSKY1C
RSKY1D
[textures]
TEXTURE1

And updated textures1.txt to build the default SKY1 texture from multiple patches, with appropriate offsets:

;Format of textures:
;TextureName	Width	Height
;*	PatchName	Xoffset	Yoffset
SKY1        	1024	128
*	RSKY1       0	0
*	RSKY1B       256	0
*	RSKY1C       512	0
*	RSKY1D       768	0
;End

But the sky still does not pan correctly, the engine only seems to recognize the first image and repeats it instead of using the other patches.

I am putting this task on hold for now, I thought it would be interesting to try but am running a bit short on time. Anyway thanks all for the feedback everyone 🤘

Just in case you come by and check on things.

Very nice. This should be in the Doomworld Editing Tutorials forum.
