Cubemaps - matyalatte/Blender-DDS-Addon GitHub Wiki

Cubemap is an array of 6 textures for cube faces.
It's used in many games as skyboxes, reflection probes, etc.
The addon will read it as a concatenated 2D texture because Blender only supports 2D textures.

Layouts

The addon supports the following layouts for cubemap faces.
But please note that a cubemap does not support all layouts.
(Because the actual layout is arbitrary, and some layouts have different face rotations than others.)
If you select the wrong layout, the addon will place faces with wrong rotations.

Cross

Place faces in a cube net.

Cross (Flip -Z)

Use cross layouts but rotate -Z face by 180 degrees.

Strip

Place faces in a row.

Import

You can import cubemaps in the same way as 2D textures.
And you can select one of the layouts with Layout for Cubemap Faces option.

Export

You should select Cube or Cube Array as Type property.
And You should select one of the layout with Layout for Cubemap Faces property.

Cubemap Array

A DDS file can store an array of cubemaps.
The addon will load it as multiple 2D textures.
See here for the details.
