Hammer Compiles but map doesn't run in Portal
I've been developing a couple of fairly complex maps over the last few months without any problems. However, on sunday, the one I was working on stopped running in portal even though it appears to compile correctly in hammer - and even an earlier, previosuly working version didn't run. I did a clean install of Stream and Portal and it hasn't fixed it
Before I had this problem, the way I ran the maps was to simply select "Run map..." and then had "Don't run the game after compiling" unchecked. After the map compiled, the hammer/steam splash screens were displayed followed by a Portal 2 splash screen with the map loading progress dots in the bottom right.
When I now compile the maps, the steam/valve splash screens displays as before but then one of two things happens:
- the Portal splash screen with progress dots are displayed but, when the progress dots "count" up to the second dot, then the Portal menu background screen is displayed but without the menu - and at that point it just hangs.
or
- After the stream/valve splash screens, Portal just goes straight to the Portal 2 menu without running the map.
Now, what I would like to know is whether anybody else has seen this behaviour before and/or is there a Portal log file anywhere that may give some clues as to why Portal is behaving like this and not running the map.
By the way, the same thing happens when I just double click on the bsp file.
I was just getting to the point where I was close to publishing the maps and unless I can fix this many hours of work would have been wasted! Help would be much appreciated.
Two things: first, make sure your BSP file has less than 25 characters. (That fixed a problem like that for me)
Also, would you mind copy/pasting your compile log?
Finally, welcome to TWP!

Thanks for the quick reply - and for the welcome.
The filename is less that 25 chars. Unfortunately I'm working remotely at the moment and haven't got access to the log file - will post as soon as pos (should have been better prepared!)

Sounds to me like your file location is not properly transferring the map to your location. Portal 2 is fine finicky about file locations. The problem is most likely your remote location to the file. When you last compiled the map successfully were you accessing it remotely?
Also, would you mind copy/pasting your compile log?

Log file for the offending map below. This has been run on my Vista laptop and exhibits the same behaviour as when run on my Windows 7 desktop (I'm still working remotely so copied the vmf file to my laptop to run it - just takes longer to compile!).

As you can see from the log file above, the folder I used was:
C:Program FilesSteamSteamAppscommonPortal 2sdk_contentmapsMyMaps
I've also tried it in:
C:Program FilesSteamSteamAppscommonPortal 2sdk_contentmaps
and it still doesn't work.
For info, I've noticed that a bsp file (th1_final (47).bsp) is also generated in:
C:Program FilesSteamSteamAppscommonPortal 2portal2maps
so I assume that this happens when Hammer compiles the map.
Have you tried not using parenthesis in your map name?

[/spoiler]Good call - but this has only highlighted that I was looking at two different problems. In my original post I said that "and even an earlier, previously working version didn't run" - and the file for which I posted the log above was the previous file which I had backed up (marking it by a version number in brackets). I've just tried running again after renaming it without the brackets and it ran OK.
However, I still have the problem with the latest version of my map which still doesn't run - below is the log file. After it compiles, and when portal fires up, it goes through the splash screens to get to the one with the progress bar but when the progress bar reaches two dots, it goes to the blank menu screen where it just hangs.
I could go back to my previous version and continue with that but I really want to try and find out why it's not running so I can avoid doing whatever I did.
By the way I've checked and the bsp file has been created in:
C:Program FilesSteamSteamAppscommonPortal 2portal2maps
and when I double click on the file it still doesn't run (portal starts, gets to two dots on progress bar, and then hangs).
The log file is:

Except for the many models, brushes and the high ent_data that you have, which should let you run your map anyways (and maybe crash to desktop saying you have "no free edicts"), I don't see anything really bad.
However, your compile is saving your BSP always under your /sdk_content folder, hmmmm.... are you sure you are trying to run your latest version of the map? to me it seems that you are not running what your compile log shows, but some other old version of the map.
You should check out your hammer editor settings... Go to "Tools > Options > Build Programs Tab" and find "Place compiled maps in this directory before running the game" below.
Then change the path to: $SteamUserDirportal 2portal2_dlc2maps (this will allow you to buildd cubemaps later after you do a Full compile).
useful tools and stuff here on TWP [spoiler]
[/spoiler]Thanks josepezdj. I've got it working now but I don't know what the real cause was. There is one question that this problem raised thought - is there a log file for Portal 2 which records any errors during loading etc?
Specifically related to your last post - it does cause me to ask a few other questions though - and ones which will demonstrate that, although I'm having fun creating maps, I really don't understand the mechanics of what's going on!
What drives the ent_data content? Are there some simple rules on how to reduce it?
,
Is this a problem only during the compile or could it be a problem once the BSP file is run? Ie, could this cause a problem if I publish the map? Even though it runs on my machine, could it crash on others?

The settings were actually set to "Portal 2portal2maps" and the maps were saved in both the sdk_content folder as well as the portal2maps folder. I've changed it to dlc2 folder - but what does dlc stand for and has that folder got a specific purpose?
And now what is probably the most stupid question - what do you mean by "building cubemaps after you do a Full compile"? Is this the process for publishing (which is the next great challenge for me!)
ent_data is entity data, basically all the stuff entered in entity properties like names, outputs and keyvalues.
The entity limit is the same for all Source engine games, so if it doesn't crash it shouldn't on other computers.
DLC stands for DownLoadable Content, and the folders portal2_dlc1/ and portal2_dlc2/ store the files for the two main game updates, Peer Review and the PTI/Workshop respectively.
Cubemaps are basically special screenshots used to render reflectivity in materials like glass or some metal. To build them, run "buildcubemaps" in the console after the level has loaded. You want to have placed some env_cubemaps near any reflective materials, as this is the location it takes screenshots. (It uses the closest env_cubemap to the surface.) There's a bug in Portal 2 which causes a crash if the map is not in the latest dlc folder (dlc2 now), so that's why you want to change it.
Full Compile settings are just some preset settings for the compilers, and tell them to take more time than usual to generate a better looking map. You probably also want to run this when adjusting lighting, as it will appear different. Fast compile is the opposite, where the compilers rush a bit to get a quick map so you can test it.
