Help with changing, customizing unit textures

Hi, everyone,
I was having a chat with a good friend about customizing textures and how to change/improve it. Although I got a source named, I wanted to ask this point here as a question because I couldn't find it in the forum. --- does anyone know which program can be used to edit the textures of units (.dds files)? Do you need an import/export plugin similar to Blender 2.8? --- If anyone can help I would be this one, very grateful.

You can use this tool to convert to and from Direct Drawing Surface (DDS) files:

edit: it does require a nvidia account. But not* one that is legit 🙂 . You can for example use a temporarily email for registration:

A work of art is never finished, merely abandoned

I'll test it right away, thank you very much Jip
