I'm implementing my own vision for the interface of the Wrath and Necromancy buttons. When importing .dds textures, I'm facing a problem where all the unused space in the texture (with a transparent background) turns white in the game. The file format and the one specified in the xdb match. I tried changing the options when saving, but it either didn't change anything or the file was read incorrectly by the game. What could be the problem?

I'm using the Nvidia plugin in Photoshop to save, and the preview shows everything as it should be.

Do you have Paint.net? The plugins in Photoshop are useless. If you delete everything around the icon in Photoshop and save it as PNG, for example, or even with a plugin for dds, it will have a white background.

The problem is solved. (Please change it to BC2 in the title, I made a typo, as I meant DXT3)

The solution to the problem, as mentioned above, lies in the incorrect color. However, I will describe it in more detail for future reference.

1) The very bottom layer - the background - must be black, and the texture is drawn on top of it.
2) Select the entire texture separately from the background and create an alpha channel, fill the selection with white.
3) Save in BC2 or another format. Disable MIP maps.
