Avoiding pixelated images????
Hi guys. I have a big problem. Im working on .DDS images, and when i save em, i do it with mipmaps activated and with DX5 compression. The problem is the final saved image will result pixelated with horrible results, and i cant affor that. I needed to use photoshop instead for avoiding this issue (i dont have the same problem using photoshop.) , cuz the images i am working on have light areas and auras that CANT BE pixelated (no sense). Anyone knows a solution to this ?? maybe i should use different values when i save the image???

This is a screenshot of the original image:

And this is how it looks after i save the image in DDS:

RE: Avoiding pixelated images????
Do the pixels appear during the editing under Gimp? Or do you discover them when using the DDS later? Can you save the image as PNG before saving to DDS to see if there is a difference?

If my little spanish is good, the top image is one layer, the bottom one is 11 layers, what do the layers look like?
Can you describe the changes you did? Can you put the XCF somewhere where I can retrieve it?

If i save the image on png, all is ok, and the saved image is not pixelated, but i need to save it in dds so i can apply mipmap filters. So i guess is when i apply the mipmaps when the image gets pixelated.

The only thing i do is to "cut" the original image and rotate it 90 degrees. Then i save it as DDS. As i said, if i use Photoshop for doing the same thing, i dont get those pixelated images. I know the DDS filter is still in development (and with some bugs that i think will never be fixed..) but how is this possible? i really dont want to come back to photoshop.. sigh.

I just discovered that i can avoid to saving pixelated dds files just avoiding to save the image as compressed image. The size is about 4x but thats the only way u can get non "corrupted" DDS files with mipmaps using Gimp..

Maybe, but the weird thing is the compression of dds files works perfect in photoshop... Huh
