You only need firestabber.zip for the textures. To set up, download and unzip firestabber.zip in tf/materials (so you should have tf/materials/firestabber/tiles now). The pngs and map aren't a part of the texture pack, so if you don't care about them just download firestabber.zip. DOWNLOAD HERE:
https://www.mediafire.com/folder/z2q63o3iij3ed/Tile_TexturesI've made a 128x128hu tile texture pack! 91 solid tiles, 8 glass tiles, x2 for seamless variants. Also included are the solid tile & glass tile outlines (if you want invisible tiles I guess) for a total of 200 textures. No credit required, I want this to be as easy as possible to use. I've included the layers for making solid & glass tile borders as pngs if you want to make your own textures fit in. The map has a swatch of each texture. I just made it when double-checking everything, but I figured maybe people like to look at textures in-game before deciding on using them in hammer. Happy mapping!
