2D-Editing Creation Tutorials

This tutorial shows you have to properly save .dds & .tex files to work in League of Legends and what you might need for programs to be able to work with the filetype.

You have to copy this “About” text under Post settings in the “Excerpt” space in order for our tutorial lists to work properly. Try to make it not too long.

If you encounter any issues with this tutorial or you don’t understand part of it, you can ask for help on the Killerskins-Discord server.

Explanation of compressions

.dds itself has a lot of compressions, however LoL mainly is using 2. Compressions are mainly written as BCX and DTX X, it varies between programs what the main name is.

Here is the difference between compressions on SG Janna. Her tassels usually are transparent in-game.

BC1 / DTX 1

This compression supports no alpha / transparency.

BC3 / DXT 5

This compression does support alpha / transparency.

So basically if you use BC3 / DXT 5 you are always on the safe side.

Saving a .dds

I will be saving with a BC3 compression in all the following guides, but see point 3 for a compression explanation.

Photoshop + Nvidia Texture tools

Go to File – Save as… and select DDS

Next, under Format select “BC 3 RGBA 8 bpp…”, turn off “Generate Mipmaps” and under Compression Quality select “Highest”.

Then press Save.

Photoshop + Intel Texture works




in Gimp, make sure your layer does not overlap or is smaller than the image boundaries. If that’s the case, the image size will be changed.

.dds export in Gimp also only supports 1 layer, so merge visible layers before exporting.

Go to File – Export As..

Name the file however you need and add the extension .dds

For the .dds settings, set it to this.


Adding another image that is larger as a layer will expand the canvas.
To prevent this don’t drag and drop the image, copy and paste it and it will prompt to expand the canvas or keep its size (it will be pasted on the background layer, make a new layer and paste the image on it)
If the image is outside of the canvas it WILL NOT be expanded and saved as a whole, just what’s inside the canvas

When image editing is done click file->save as
On the dropdown saying .png or .pdn select Direct Draw Surface (.dds)
There is another dropdown after where its BC1 linear DXT1 by default, set it to BC3 linear DXT5, other settings are fine

If there are multiple layers will need to flatten the image.
Simply press flatten and the image will be saved. If you want your layers back to edit something just undo.

Converting between .dds and .tex

Export your .dds with the BC3 / DXT5 compression, because it will not work otherwise.

Take your .dds file and drag-and-drop it onto the tex2dds.exe.

Then you get a .tex file of this texture.

If you need to edit a .tex file, simply do these steps the other way around: drag-and-drop the .tex file onto the tex2dds.exe.
