I am working on my first map (ever, in any game) and I have a question. I've seen a few people on threads here say "make sure you use TF2 water!" or something similar. My question (or questions, rather): How can you tell if a prop/texture/whatever is from TF2? Can I filter out all non-TF2 textures somehow (easy enough for props)? What happens if you use HL2 assets in a TF2 map? Will they not show up for people who don't have the Orange Box or something? Thank you for tolerating my noobness.
