Problem with retexturing

[AGreatWeight]

I'm attempting to make a custom holotape retexture to go with one of my mods. My problem is this: after loading the dds file into photoshop, the background is not transparent, but white. This causes a lot of colour bleed along the edges (though I'm seeing it everywhere) which makes it impossible for me to layer the retexture files as I cant make out where the actual edge of different parts are.

 

I've scoured the internet trying to find a solution, and along the way I've seen numerous images from other mods (of the dds file open in photoshop) that show a non-white background; usually black or grey. Also, I've not come across any tutorials online that even mention anything about this specific problem and how to avoid it.

If it's something that I'm doing wrong, then any pointers in the right direction would help!

If I can't fix this, then it looks unlikely that I will be able to complete the retexture, so any help would be gratefully appreciated.

Hi, ehm, I don´t know wich type of texture are you editing, I´m referring to a diff or a spec or a norm but the holotape only uses the diff. The problem could be the dds plugin you have for photoshop

Sorry, I uploaded a pic but the link wasn't working - reuploaded now. The pic is the HoloTape01_d.dds, the normal and specular .dds for the holotape also display this colour-bleeding when I zoom in. Someone else suggested using the Intel .dds tool but it's only compatible with PS CS6 which I don't have.

The plug-in I'm using to import .dds is the Nvidia one. In the channels tab, I've noticed that RGB, Red, Green, and Blue are there, but no Alpha channel is present. Could this have something to do with it?
