Hello again!
Well, I was testing a co-op map i'm creating and I saw I needed to rotate some info_particle_systems. Closed the game, opened Hammer and did it. Compiled the map once again, opened the game > ss_map [louder]map_name_here[/louder] and some seconds after map started loading: Portal 2 stopped working windows will find a solution to it.
I tried removing the info_particle_systems from the map (got mad with them heh) and of course it didn't worked. Also tried restarting the computer, but nothing.
It happens only with this map, the others are loading normaly.
Well, what the hell could it be?

Thanks in advance!

Try verifying your local files (Steam Library > Portal2 > [RightClick] > Properties > Local Files > Verify Integrity)... maybe some files got screwed up.

Some files did get screwed up and Steam updated them, but that didn't helped
Thanks anyway!

Well, that crash to desktop can be caused by many reasons... I doubt the mere rotation of some info_particle_systems is the cause. Try hitting Alt+P to check for problems (and fix them if you think they could be the reason for the crash). If that doesn't work, I'd suggest you to go compiling your map partially by means of cordons (with the cordon tool) to isolate the issue and locate it more exactly.

Well, the map shows some clear issues when compiling. When vrad is running, it warns me about too many light styles on a face at <directions>. But that was happening before and the map worked normally. The compiling process also takes more than 1 hour on PortalFlow process, that sounds totally wrong. This map has a BTS area, outside of the chamber. This BTS is closed by a box with a skybox texture on the top. The rest of the box walls are all toolsblack_noportal (don't know if the name is right, I'm not on my computer right now, but you know what I'm talking about). The outside area is all textured with nodraw texture. I think this may be useful information...

So it's a Wheatley themed map I'm guessing then?

The too many lightfaces mean there are to many lights w/ names and dynamic lights on a single face by the way...the map will still compile, but I'd recommend looking around and trying to clean this up.

Try putting the map, or most of the map, inside a cordon box, and see if that compiles? Just the test area. That will help tell if it's a whole map problem, or just part of the map.

Did you use any strange symbols in the map name like *&^(#%? Having these in the map name can screw it up. Is the name of the map the name of anther map you made or one by VALVe? That might screw it up too.

Good luck!

I'll try some of the suggested tomorrow. I'm going to travel to another city for one week so I won't be able to do a lot of things soon
Thanks for the awnsers!

EDIT: I've forgot to awnser some questions, was really tired yesterday, anyway:
- It has the same feeling of Wheatley maps, but it has Glados's control and the BTS areas are not being destroyed
- Yes, I have named some lights for yellow light on laser catchers and red on emitters. There's another way of doing it without making compilation process take hours? They are activated and disabled in I/O when the emitters and catchers are powered or unpowered

Good news! I've found a backup copy of the .bsp when I didn't start to name lights and the map was free of any warning on the compilation process (although it takes some time, like 20 minutes or more). Well, when I get home I'll get back to work, thankfully!

These accidentally backups are amazing

Seriously just how many bugs are there?!

A lot... it gets really fun when you start getting into random hammer and portal crashes.
By the way, for any map makers I can really recommend using a tool like TortoiseHg for version control of your vmf files. It saved my skin a few times when dealing with nasty bugs.

I recently started doing this. It works quite well once you get the hang of it. Highly recommended!

Well, I think I've figured out what is causing the game to crash...
I've forgot I have no more skybox textures on my map but env_sun and light_environment entities are still on the map, I've forgot to remove them.
Still a theory, though, I'm only going to figure this out on sunday, but if it doesn't solve the crash problem, may increase compile speed!

And HMW thanks for the tool! I'm totally going to try this out
