You aren't editing your IWAD right?

I dont know what IWAD is...

Your IWAD is the main game file, usually Doom2.wad, or Doom.wad.

Don't ever edit that (unless you really know what you're doing). You'll break the game.

I don’t think so. It seems he is creating a PWAD for plutonia.wad with TEXTURE1 / PNAMES created from the scratch with only the custom textures / patches of that PWAD, without importing these lumps from the base IWAD as the very first thing to do and edit them to put the custom content.
