Im trying to export the map I made buy it says it was, "Unable to find materials." I got to this point watching the tutorial that you can download off this site but then everything got confusing when on the texturing video he used a new map. I'm thinking about starting all over, but this is a pretty good map and it took a while, what can I do. Also, the textures aren't appearing and I think the error has something to do with that.
