This is not the thread you are looking for
I kinda tried to remake that skybox at the end of portal 2:

Seriously wished all that stuff was in hammer >:C
Fracture, there are many 'real' skybox textures out there. I've got like 20-30 skyboxes, and ofc I've got some with clouds and such that look really pretty... Ofc, that pic of yours and Lamarr's video are showing an animation made by the Source FilmMaker, and that animation cannot be made in hammer.

[/spoiler]Well I didn't know that. And As i already said, those textures you posted didn't seem to work. something went wrong and now my skybox is trippin again
Did you also download the test map I posted? Maybe you are not creating the sky box well.
Did you place those textures into /portal 2/porta2/skybox?
If you prefer, post your map, the latest version you have and I'll check. I'll modify whatever it's wrong and post it back.

[/spoiler]your map went insane too. I think my hammer is fucked up
Fracture, there are pleanty of free and already made skyboxes out there for you to use.
Check gamebanana http://gamebanana.com/css/textures/cats/28 for an appropriate nice looking cloud sky.
If your sky seems to still stuff up, check the .vmt's that they give you with the download. Just like I said before, add in the $hdrbasetexture value in and save it.
Mel, it is easier to have this kind of .vmt using the UnlitGeneric (instead adding the $hdrbasetexture command into a .vmt with the 'sky' shader):
- Code: Select all
"UnLitGeneric"
{
"$basetexture" "skybox/sky37bk"
"$nofog" "1"}
And yeah! Gamebanana has many awesome custom skybxes, the best ones are made by Komaock

Wow, that looks beautiful!
I read about one way to achieve the moving cloud effect the other day: Material Proxies.
