OK.
A. Seventh~ I found materials.txt in pak0, and I see what footstep sounds are available....I assume I need to put the name of my custom tex in there with the proper letter heading to get the sound I want....which leads me to three more questions:
1. This will hopefully work for my preview while using Hammer, how do I transfer this tex information to my map when completing it and playing my multiplayer map in Steam? I went into my steam folders, and found there is no materials.txt in my sound folder (nor in my old HL sound folder...) I only found it in my pak0 file....do I need to extract that file and place it in both my new (Steam) and my old HL folders to make it work for previewing in Hammer/playing finalized bsp in Steam?
2. Does it matter in which order I add my custom tex in materials.txt in that list of tex/sound attributes
3. What if the sound I want is NOT on the list of possible footstep sounds? I see metal, ventilation, slosh, dirt, etc......I want to have my grass sound.....Do I add the custom .wav(s) somewhere and then make a special letter to refer to that sound with? If so, how do I tie a certain letter to a certain sound?
