Mirrored boulders like the sort you see in pl_upward (pretty sure that's the map that has them all). Normally I put new props into a completely seperate folder to avoid conflicts, but for convenience these will unpack into props_coalmines. This shouldn't be a problem since these are named uniquely, but simply be aware of it. This is a modification of Valve content. Each has slots for additional skins, but skins are NOT included in this archive. If you wish to use these extra slots, place the skins in materials/models/props_coalmine and name them thusly: boulder1_mirrored_a.vmt boulder1_mirrored_b.vmt boulder1_mirrored_c.vmt boulder1_mirrored_d.vmt boulder1_mirrored_e.vmt boulder1_mirrored_f.vmt boulder1_mirrored_g.vmt Also note that boulder3 uses boulder2's textures. You will ONLY need to create a custom skin for boulder2 and boulder3 should automatically be textured identically. This is the way Valve did their versions, so I kept the convention for the mirrored ones. Keep an eye out for a texture pack by BoyLee (TF2maps.net) that will compliment this set. Readme, screenshot, and 22 model variants included in this zip.
