Problem with transparent BLP

[klemen]

I am using Warcraft 3 Viewer to convert tga to blp but I am unable to produce transparent background in blp. I know it's possible because I somehow did it in the past and if I extract those older icons they have proper transparent background.

I tried 24bit tga, 32bit, compressed, uncompressed.. nothing works. If I use black background I get black background blp, if I save it with transparent background it becomes white in blp. Tga preview is also white so I suspect I am saving it wrong. Google hints at alpha channel but I am pretty sure I did not use it the first time.

So, what is the proper way to save the tga with transparency?

I don't think .blp supports transparency. However, you can use .tga files in the world editor. So if you want a icon with transparency just import the tga version and it should work.

I attached an example blp, if you open it up in W3 Viewer it clearly has transparent background. I just don't remember what the heck I did the last time. It just "worked".

Of course it is possible. I don't know what is with the viewer application you use but magos model editor can convert transparency from TGA and PNG to BLP just fine.

Yes, Magos model editor from PNG seems to work. Thank you.
