SkyBox Texture

[SLi78]

Hi everyone,

i want to make an outside level.

So, i set skybox active and tried some jpeg's but it doesnt work.

1. Had a skybox texture to be in dds format?
2. Must it be a resolution like 256*256, 512*512,...

If someone can help, would be great.

A skybox is a collection of six textures arranged to form the inside of a cube. A dds file can hold multiple textures needed to form a skybox, but you need to download some third party software.

The Gimp has a plugin for working with .dds files there's also a plugin for photoshop somewhere.

To make a skybox in Gimp you need 6 layers named to their correspondence position in the box (up, down, left, right, back, front.) Once you have these layers named exactly as above when you enter the save dialogue you have the option to save as a volume map. You can then import this into the material editor.

It might take some fiddling around to get things aligned properly but it's not too much of a hassle.

OK, thanks.

I found one texture yesterday which i can use, making one at my own would be to much

To easily repaint or create new textures and open or save them as .dds files, I use
Paint.NET it's a really handy program for that... and it's totally free. No whining about upgrading to a paid version either. it's here: http://www.getpaint.net/

I found that if You'll use Volume Map option in Gimp DDS exporter, the output file is not visible in Material Editor. To make it work, You have to rename the layers as follows: positive y, negative y (for up and down), positive x, negative x (left, right), positive z, negative z (front, back). With those names in place You can use Cube Map export option as intended.

Look under Skies 360, there you'll find finished cubemaps

I used this tool for cubmaps:

cgtextures.com has a tutorial how to do cubemaps as well.

can we have a little more information on how to create the skybox dds and what is the exact layout the amnesia engine needs?

I downloaded a jpeg from cgtextures, then i installed the nvidia plugin for photoshop, i open the jpeg then i export it as .dds file, but when i want to save it, the plugin tells me i need 6 different images. I thought that the cubemap jpeg from cgtextures was enough? What do i need to do? Do i have to cut the jpeg into 6 different images? But then, what?
