Insurgency (Custom Skybox Leak)

Your vmt seems to be correct. (You don't even need "$nofog" 1, "$nomip" 1 and $ignorez 1 to make it work afaik)

The images you want to import should all have the same resolution. 1024x1024 should be fine.

They should be simple files like tga or even bmp. No alpha channel needed.

Open vtf edit and open your image via "file -> import". The vtf options can be the default settings.

Don't forget to flag Clamp S, Clamp T, No Mipmap, (No Level Of Detail (?))

Your 6 vmt files will be vegas_01bk.vmt, vegas_01dn.vmt, vegas_01ft.vmt, vegas_01lf.vmt, vegas_01rt.vmt and vegas_01up.vmt. The vtfs the same with .vtf ending.

Be sure to save all the files in the correct folder and set the correct skyname in Hammer editor (vegas_01)

Maybe post your settings in vtf edit, if it still doesn't work.

Actually, you can make all of your vtf's (except for the upper one) 1024*512 or 512*256, as the bottom part will probably never be visible and this will lower filesize a bit. The bottom one can be 16*16 or something like that, since you will never see it anyway.

Nice to know.

Well, I stuck by Valve's recommendation here.

Already thought about what you said, because these parts of the skybox are never visible as you said, but unfortunately didn't try it yet.

Well, I gave it a try immediately.

(1024*512 resolution except the upper (1024*1024) and bottom (16*16) textures)

Found out, that you will have to add

$basetexturetransform "center 0 0 scale 1 2 rotate 0 translate 0 0"

to the vmt (of ft, bk, lf and rt), if you don't want the images to be stretched vertically.
