I've been trying to pack some custom textures into my map with PackBSP and still getting missing textures. I had done this uploaded the map to our server for some play testing, yet when people played they complained of missing textures. When I tried re-packing I noticed something - some of the standard assets that should be there already were also not being packed! This is the first time I've had to pack a map since the SteamPipe update, so I suspect I have not set something right. Could someone advise me on how and what I need to do to fix this please?
