Are you asking how to create them pixel by pixel in Photoshop or are you looking for the technical specifications so that they can be used in the game?

I want to apply text to a textured surface. Just text, with no background, like the grafiti in HL that says "Surrender Freeman!"

I need to know how to make these in Photoshop. I tried transparent background, but it seems the .png format didnt keep it.

add an alpha channel to your image.. that should do it (white is visible, grey transparent, black invisible)

Won't work atleast not if you are using Photoshop 6, well didn't work for me.. The Adobe boy's screwed up with the PNG plugin, version 5 was the last version which did it correct. I'm wrestling with a simular problem at the moment, Joe (mainly) and me (just hupping along) are working on the right way to do it. As soon as i have some more info i will surly post it.. Unless some one beats me to it.

I still don't get why you guys are having problems with it, dec. Adding an alpha layer or mask never worked for me in Photoshop 6. I used layer transparency for my GUI buttons: I deleted the background layer, set partial transparency on each layer, and Save for Web under the File menu. You just have to make sure the transparency box is checked.

Well the whole problem is, It doesn't work...

Believe me i have tried to many way's already, i didn't get it to work, it's probably me but still..

I'm not an expert, more like a newbie actually, but i have been investing alot of time in it and i didn't manage to do it yet, i hope that will change soon =O)

Making the alpha layer in PS 5.5 and 6 is not the problem.
The problem was when you opened a png (like the player skins) from Tribes 2, then you could not seperate the alpha layer from the RGB like you can in PS -->5.0 and every other image prog.
All you would get was a greyed out version of the skin.
But making and alpha from PS 5.5 and 6 is not a problem, it works fine.

Btw, you can get rid of the greyish look of the png by selecting "image/adjust/autolevels" then it will restore the bitmap back to its normal.
