Relaxation vault.
Have a look at this link:http://www.interlopers.net/tutorials/25686
Maybe that might help you. It's pretty complicated for me. There's something as material modify control. If you manage to make it make the clock also an instance.
I would probably be using this instance in my map. It will save me a lot of time. Thanks.
Also I am not getting shadows on static and dynamic props even if i enabled shadows on the props.Any hint?
I've tried to use those textures with the material modifier, but they don't work in portal 2, the textures don't exist anymore. As I said before, I'd like to keep this instance clean and I'd like to only have portal 2 stuff in it.
Only happy to see this used in more maps 
The relaxation vault is what the very very first part of portal 1 looks like.
To create this in portal 2 takes quite a bit of time and effort. I created this because I wanted people to start in this room in the mod I am making.
After I finished this I put the vmf file as an instance. This means that another mapper can use this INSTANCE to INSTANTLY create the relaxation vault in their map. The only thing they have to do is create a func_instance and look for this instance file and they have the relaxation vault in their map.
This is NOT a map, this is something mappers can use to add this to THEIR maps!
So I can make a large empty block(Big enough for the room to fit in) do func_instance and click this vmf file and it'll load as a playable part of my map in portal 2?
Can you do the same for the old aperature science hotel wake up vault? Or is it the same thing?
Here's some free mapping advice:
Don't put stuffs in big empty blocks; it gives a lot of problems.
Instead make it line up with your map geometry.
But yeah; you can put a func_instance, click this vmf and it'll be loaded into hammer.
If you then compile the map into a bsp, you'll be able to play it.
I'm not planning on making this for the old aperture science hotel wake up vault; you can just de-compile that map and see what's going on there. 
You could post questions about things in the hammer and modding-sub forum.
If you want feedback on a work in progress map you can put it in Work In Progress
etc
Hey Lp,
Dunno if you will find this helpful but this is what is used in portal 2 for countdown timers, like in GLaDOS's trap test, and the final boss battle. The entity's name is vgui_neurotoxin_countdown.
Hope that helps!
