Hello again, I have been making some progress in the use of radiant, but now im stuck.
There are a few textures I like , these textures are in the map thunder.
I opened the pk3 file and looked for the textures, but I realized that all these files have the extension ". Webp"
the question is:
How do i open these textures to edit? The Gimp does not do this ...
Do I need Photoshop or some other proprietary software?
