GIMP issue

[PutraenusAlivius]

I have a .png file with an Alpha Channel. Got it from CGTextures.
But anyways, I resized it from 766x1024 to 512x512. No big deal.

But when I export it to .dds, it's all black (The alpha channel). I need help.
Probably a step by step.

[The chaser]

-Open your image
-Then, select by color (Majus+O)
-Now, select the part you want to be the alpha part
-Go to Colors<Color to alpha
-Say "Ok"
-Now all that part should be covered by grey squares, which means it's alpha

Unless other programs, you must specify what part of the image is the alpha, so that's why it appeared as black.

I hope that fixed your problem

PD: I would have resized the image to 1024X1024, I find it more appropiate.

It still won't work. How about you do it? I'm not that good with images.

Here it is. Please resize it to 1024x1024 and make it a .dds. Thank you.

You need to export in DXT5 if you haven't done so already.

Still the same. I used existing mipmaps too by the way.
EDIT:
After doing that, I opened it in GIMP again. But it still has the alpha map in GIMP. Still looks invisible.

It worked! I just need to add an alpha element to the material file.
