Batch texture replace

[dvvidpw]

I have modified all of the textures/patches in the game and I would like to put all of them back into the wad, replacing the original ones. I downloaded a handful of different editors, but can't figure out how to replace the textures all at once. Is it possible with any program?

Well with Xwe anyway, you can do this by extracting all the textures 1 at a time to a directory and then you will be able to (loading them all at once), per wall texture patch and then per flat texture.
However your question somewhat throws a loop, as I'm not sure if you want to replace existing textures in your IWAD or create a new stand alone PWAD.
It would be wise to create this as a pwad.

Anyways, there is a batch version out there that will extract the wad (all lumps) by command line if you want also.
