Okay, I finally found a way for Voice Clips via Ambient_generic. But for now, no cheography.
At the moment there is another problem.
At this point I am doing my maps in the in-game puzzlemaker, then export them with the developer console. Then I can open them in Hammer and just change the voice clips or add some.
But my question is ... when I export the map and open it in Hammer, then I do it this way:
Map -> Entity Report ...
Then I look at the Ambient_Generic thingies and search the sound clips that are used (not that hard to do). But when I click "go to" on the chosen entity, it opens another .vmf file.
In the case of mine at the moment, it is the .vmf file from this path:
C:\Program Files (x86)\Steam\SteamApps\common\Portal 2\sdk_content\maps\instances\p2editor_1960\elevator_entrance.vmf
I used the Style Changer software for Portal 2 to make my map have the style of the salt mines in 1960s. Then I exportet it into .vmf so Hammer could open the file from the puzzlemaker.
There are two problems now:
1.) The opened map in Hammer does not export the textures used in the in-game puzzlemaker. So, when I compile the loaded map for example to test the changed sounds, it uses the standard graphics from Portal 2. So the chamber inside does not look like 1960, it looks like "normal white and black walls". In addition, the Reflection Gel is not dark grey or silver anymore, it is transpearent now (only outside of puzzlemaker and only on ground and walls - when it falls outside the pipe the gel is still dark grey / silver). How can I fix this?
2.) It seems the exported map is splitted into two files which are connected through a "portal world door" or something like this. So, when I want to change the sounds from the exported map, it does not only change the sound clips for this one map, it changes the sound clips for every map which uses the 1960's style - in my case, the file:
C:\Program Files (x86)\Steam\SteamApps\common\Portal 2\sdk_content\maps\instances\p2editor_1960\elevator_entrance.vmf
So '\p2editor_1960\elevator_entrance.vmf' is the instance file for the 1960's files, if I am correct (it's difficult for me to understand everything of that correctly, because most of this I discovered by myself today ... learning by doing).
But I searched the whole files in Hammer for a connection between my exported map file (which is the chamber inside) and the Elevator Entrance Instance (which is the chamber outside, the salt mine). But I didn't find anything related to one of these files. No instances. The only thing I found in the '\p2editor_1960\elevator_entrance.vmf' are two "linked_portal_door", one at the entrance to the chamber inside and one at the exit of the chamber inside. But it has no inputs or outputs. That confuses me. Where are these two things connected?
That is very important for my sound files, since I don't want the same sound clips for every map that uses the same decade.
I hope you understood these two problems and can help me. It's still very confusing and complicated. But I try to learn.
And yes, I asked Google, Youtube and I searched the Developer Site for this. I found nothing related to my problem, since most or all other mappers do the maps from scratch in hammer.
But that's way too complicated for me, since doing maps in the in-game puzzlemaker is much more fast.
