In Game Images

[Ultimatony]

If my multiboard system can't be fixed I'm going to use images.
I'm making an image in photoshop,
Even though pic is 64x64 - and size in game is set to 64 I have this huge white area past the picture.
Image is a TGA and imported into my map as is.

Is there a way to use transparency in game?
How do I have all that white?

You need to add 1px wide transparent (alpha) edge to the image. Keep it at 64x64 still.

the gray/white boxes means alpha doesn't it? (and there is a 1px transparent on right side)

No, that is transparency but that transparency is not conserved with .TarGA files. For transparency, you have to click the Channels tab and then create a new one. (click the little button that is where "New Layer" normally is, or just use the toolbar, Windows -> Channels) Then use your brush to alpha out whatever you need to.

White = Add/Maintained
Black = Remove (transparency)

So basically, whatever has the checkered cubes right now should be blackened in that new alpha channel. Then just save as .tga (do 32 bits/pixel or 24 bits/pixel unless you are very concerned about file size [in which case, do 16 bits/pixel], because images in wc3 end up being crap in terms of quality if you save it with less quality) Then convert it using Wc3Viewier or BLPLab.

It should end up working correctly. However, you should also add a 1px transparent border on the bottom portion of your image.
