I was recently making Portal maps with the first Source SDK. When I tryed Portal 2 Authoring Tools, I loooooooved it because of its simplicity.

On the other side, I wasn't able to find how can I make a mod like with Portal 1, configure the SDK to have the BSP on the mod folder, modify the backgrounds, name of game; have the mod on the Steam Library...

Thanks a lot !

P.S. : Sorry for the bad english, I'm french
P.S. 2 : Will the new Puzzle Maker able to export our maps to VMF format ?

I used this as a guide to try a simple one...

EDIT THE DIRECTORIES, AND YOU'RE READY TO GO.

I've only tried it very quickly, to see how it worked.

I've not got to the stage yet where I have to create a proper one for my map... will be doing that 'soon' though I think.

Maybe see how others have done it, I know of one mod called 'The Core', take a look at that and maybe it can help you see what you need to do.

It worked for me
Maybe try again, and go through it step by step?

I still have no sound

Edit : With some modifications of singleplayer.res I'm able to use the New Game/Continue/Save & Load system of the game but it crashes everytimes I click on "New game" =/
