i have always wanted to do black mesa styled maps but the old stuff just wasn’t legit enough, i only want to make maps and little in game mods
now so far i have added black mesa to hammer and i can create brushes and all the right textures are there (i don’t know about the entities ) … the only problem is the 2d screens are missing the grids, but if i draw out a block and hit enter and then play with the camera i can see it but its impossible to map that way … so the main question would be … how could i copy and paste all of the mapping materials to another game so i could use them , or how could i properly set up black mesa for mapping … again i don’t intend to use these commercially i just wanna have fun with some maps for single player 
Me to buddy, how did u add black mesa to hammer editor? I am sure if i read through the hammer editor tutorials it is probably explained somewhere how to add source engime materials\ games.
Stickies exist for a reason.
Setting it up is just like setting up any other mod configuration in Hammer.
