I needed a grass texture for my map, but I was only using the halflife.wad, so I decided to make my own grass texture. I read the "Custom Textures" tutorial, and used wally to make a .wad out of a picture of grass. I only needed one texture, so the .wad was small and simple to make.
The .wad opened fine in hammer, and I put the grass texture on the floor, and then used the "Including the Textures: Method 1" to put all the textures I used into my .bsp. I recieved no errors compiling, and the size of the .bsp was noticably larger (but not that much larger because the map is small, and I only used a few textures.), so I figured the texture inclusion worked. I opened up Steam and Counter-Strike, started a new game with my map, and watched as my Counter-Strike crashed. I did not get an error.
I went back into hammer, and used the "Including the Textures: Method 2" to see if that would fix my problem. I compiled the map, and went back into Counter-Strike. The map did the same thing, and crashed.
I decided that maybe the problem was the inclusion of the textures, so I decided to not include the textures, and just run the map using my .wad. This time, Counter-Strike crashed, but I got an Error that read, File Read Failure. I did not know what this was, so I thought I might have a problem with my .wad. I remade the .wad in wally, and did all the previous steps again, with the same results. I looked at the tommy14 error page, and the description of "File Read Failure" did not help me much.
If I change the floor texture to anything other than the grass texture, my map works fine. There must be a problem with my wad, but I have no idea what it could be.
I am using Zoners Compile tools, Valve Hammer Editor 3.4, Steam, and Counter-Strike 1.6.
