Hello, i have a Problem with a "custom" made Skybox for Portal 2

First I Extracted the milita Sky from CS:S
then I Put the VTF and VMT files in the Sky Folder (had to create it) for Portal 2
Then i?ve Build a Testmap with the militia Skybox texture as Skybox
I run the Map with this Result:

No brushs etc. I can hear Chell walking on the floor but i cant see something else but the Skybox.
And these ugly Borders are there.

Any Help?
Thanks

I have the same problem too except I'm using sky_l4d_c4m1_hdr for my skybox.

I am also trying to make a custom skybox for portal 2

I made the six VTFs and VMTs using VTFEdit

Now i don't know exactly which folder to put them.

I tried putting them in a folder named "skybox" & "sky" inside 'SteamAppscommonportal 2portal2materials'

But that doesn't work or I must be missing something (or a lot of things).

Please help

Hope is a good thing

I've never made a skybox before but maybe it's something about the render order in the .vmt?

When creating your vtf file, make sure that all 6 skybox images are combined into a single file. (You need to change the "texture type" setting in VTFEdit to something like "cube map" or "environment map". (Don't remember exactly how it's called.)

The VDC has some more information on this. (Scroll down to "Creating a Custom 2D Skybox Texture".)

I remember there was a previous topic about this. You need to add the HDR parameter into each .vmt, otherwise 3D skyboxes will not work properly, and other things.

Code: Select all: "UnlitGeneric" { "$basetexture" "skybox/skyboxname_UP" $hdrbasetexture "skybox/skyboxname_UP" "$nofog" "1" }

Ok I got the skybox working by looking through how Valve has made using GCFScape

Now I have this problem.
The texture does not occupy all the area as in the image.(lines down below).

I really did not see any change in using UnlitGeneric or sky in the vmt
Also I don't know whether i am the only one having this problem :The model browser does not refresh the textures on hitting reload every time
Also is there a way to scale the texture?

bumping up this old toppic for my skybox problems.

First of I can't find the militia skybox texture anywhere in my css folders..

Second problem i've got is that i realy don't know where to edit the .vmt filees. It's posible to do it through notepad but in what folder are they hidden?

Thanks in advance again! Realy hope one of you can spare the time helping me out.

Cheers,
