Hello everyone,

After having played portal 2 and custom maps, i've decided to try building my own maps with the "authoring tools beta" (Hammer). I've already read lot's of tutorials on mapping for counter strike, half life, and portal 2. But I'm stuck with my first map !
I've build the simplest map : a room made of 6 walls, and a player (i put the player away from every wall in order not to be stuck) (hope what i say is understandable 'cause i'm french...)
Here is how my map looks like in Hammer
When i do "File > Run map..." all seems to work great, and it creates my .bsp file (as well as a .log, a .prt, a .vmf and a .vmx files).
Here is what apears on my screen while creating these files
But when i try to load the map (manually or automatically after creating the map), portal2.exe crashes with the message "portal2.exe has stopped working"...i can't figure out what's wrong...
What makes me think the problem comes from my mapping (and not from the game) is that i have no problem playing other players' custom maps.

Could anyone help meeeee ? I would be soooo happy to share advanced maps in the future...
Thank you

That's really bizzare. Try posting here and attaching your VMF.

Here is my VMF file
I haven't put any light in the room but i don't think that matters (same when i try with a light)

I am able to compile the map without any errors, and load it up without any issues. Try adding a light, maybe your system doesn't like fullbright maps or something.

You also may want to verify your game cache files for both Portal 2 and the Portal 2 Authoring Tools.

Thank you both Homer and msleeper.
I don't have anymore the problem...and i don't know why...i haven't changed anything except maybe a reboot of my computer and now it works !
Actually i did something : i installed the zhlt_compile_gui_v8 in order to compile into a bsp file not in hammer, then i spent a few minutes to find how to convert my map into a .map file, and finally the ZHLT compile GUI asked me where Half Life was installed on my computer. I didn't have the answer so couldn't make the program work, and then i uninstalled it...

Well now it works with Hammer...so i'm happy
Thanks again for you help

ZHLT is for making maps with the original Half Life. Everything you need comes stock with the Portal Authoring Tools.
