Looks nice you have some great visuals was i suppsoed to check for a message I apologise I forgot to. Good custome visuals hope you create a story one day.

No message. Looks like really big pixels

Nice visuals but message does not appear. Anyway

Um... I didn't see a message, but this reminded me of the Stanley Parable.

Let me know when you get the message working, I really wan tto know what it says!

very beautiful effect for a beginning !
I advice you to use VIDE instead of Packrat

ps: you missed the texture to the left of the exit

Thanks for the help

The message isn't there. You need to actually pack in the folder that the material is in, using a custom content packing tool like PakRat.

Downloading the tool, if you don't have it, I'll leave you to figure that out, but as for the actual packing process, you open the tool, load the .bsp file for the map, click the Add button, then navigate to where in your Portal 2 files that you placed the custom texture and select the texture to add it in. After that, you re-save the .bsp file with the custom texture packed in, and you're good to go.
