Custom Textures in Doom Builder

[The Civ]

I have recently decided to make a WAD with lots of custom textures. I threw them together in paint, opened them in SLADE 3 to convert them, yet when I load the texture WAD into Doom Builder 2, it says that I have 0 textures in that folder, even though the WAD name shows up on the texture selection screen. What am I doing wrong?

You have to add patches to the PNAMES and use these to create new textures within the TEXTURE1 lump. So you have to define your new textures in these lumps. Thats what doom wiki says. You can't just have new patches dosen't work that way. I don't know how it works however, imo it's easyer to replace original doom textures with custom ones by using the same texture names, thats how i do it. Don't know how to completely add new ones however.
