Hi.
I'm trying to make a custom decal. I looked everywhere and found out how to make them with photoshop, but dont know where to save them. Any help would be greatly appreciated.

Once you create the image file, you will need to convert it to a VTF so that you can create a VMT and place it in-game. You should check out this thread or actually this one might be better for you.

Download VTFEdit, open up your decal (or overlay) image in it, and it will convert it to a .vtf file for you. Then all you have to do is write a .vmt file with some simple commands in it, move the two files into the right place and you're done!

As long as the file is anywhere in the /materials/ directory, and has a proper VMT and a valid VTF file, it should be available. You may need to restart Hammer after you have added the image if I recall correctly.

By default those are not there, all of the game's materials and other files are packaged in the GCF.

I hate to double post but you guys have been a lot of help. You did answer the questions I had but apparently I need to do some more reading. Must still be doing something wrong I guess. Thanks.
Any more help or suggestions are welcome too.
EDIT: ok figured that out. One letter can really make the difference. Probably shouldnt try doing something new when I'm that tired.
Now I just need to find out how to make the back transparent so you only see what I want you to see...
