In this small pack you can find .vmts for all unused signages included in the original Portal 2 VPKs.
A non transparent version of the paint speed sign is included as well.

Just put the folder "signage" to Steam\steamapps\common\portal 2\portal2\materials\

Don't forget to add the vmt files in your map release, or other players will have missing textures!

File Name: unused_signage.zip

Hey, thanks for this. Most of these should prove quite useful. But I have a question. Will all of these signs work if other people were to try the map, even if they never had the original Portal and do not have this installed on their computer?

You have to put your map AND the materials into a VPK file.

this is great. Thanks for the upload Skotty.

very helpful, thanks mate.
