I can't create transparent decals!

[Dragonfire]

I've been try for ages to make non-square decals, but instead of the place where it should be transparent, it's white.
I use Photoshop CS3 Extended.
I don't know what's the problem; i think I'm using Photoshop wrong, if anyone knows how to do it properly please tell me!!

[Sorry if this is in the wrong category]

I don't think Photoshop CS3 can do that.....try Fireworks CS3 and save it as .tga.
 
 
EDIT: I just tried with Fireworks CS3 and have come to the conclusion ADOBE CS3 SUCKS!!!!
 
I will get back to you when I figure out how to do it in CS3

Perhaps it would work if you put a transparent background. (like the disc picture)

i tried skinning the disc once, but when i resaved it, it looked like a square on the robot

[Naryar]

Same for me.

It looked like a gayish transparent mix of colors.

I still saw that the disc's has a transparent background. (the whole picture is a circle)

I use Gimp 2.4.

I think that it deals with what is called an 'Alpha' channel.  It's another channel, in addition to RGB.  And yes you can do that with Photoshop.  I've skinned arenas and other objects using it for transparent sections.  Look under 'Help' and you should find it there.
If you still can't find it, then let me know.....

I think in photoshop you make 2 layers, leave on alone(should turn transparent) then make the picture on the second layer, I'm nto sure if all versions of photoshop work this way though(because I don't have PS).

Well... I just modified the Combat Arena's skin, and the ground it now like a garden, rather than banded armor plates on lava.

Photoshop CS2 you can use ImageReady, but CS 3 does not have ImageReady

Im a lot good at pic editing so let me help...
Dragonfire since you have photoshop you can use alpha chanel as Mad say...
But keep in mind these things...
1)When you save it as *.TGA for example or other format please view the options in this format to include alpha chanel in saving...
2)alpha chanel is not just have or not trancparensy... He is a value from 0 to 255... So evry pixel exept three (Example : 255,255,255) color values have and for alpha (Example : 255,255,255,255)... This mean that alpha can be a lil or a more trancparent...So you must check what values RA2 requares from 0 to 255 to "consider" it as trancparent...
Get that?

So in Photoshop or any other program just make a image as object shape in alpha to see it only by shape...But again im not sure how must be tha alpha value...Try first only 0 and 255...For example if you use 127 you must see the disk half-trancparent(half-background half-disk)...But this may not work...Im not familiar with RA2 requrments...

To users that use different program : most programs support this so it must work fine in them...

Dragonfire in end case you can send it to me to do it...if you want....
