Help needed: resizing stock DDS textures > ingame black textures (lost alpha channel?)

[Gkirmathal]

Hello,

I didn't know where to post this question, so mods feel free to move it to the correct section if necessary.

Since adding several mod packs, I noticed KSP hogs a lot memory, despite most mods not having hi res textures or having manually resized most to 512x or 1024x. For most mods this worked well (except ProcFairings)

Now I focused on a simple 50% resizing of all hi res (2048x+) stock textures. For example ShuttleWings.dds.

(In 0.9 this worked flawless because of DDS4KSP convention tool, which did the conversion and resizing correctly)

Tool I used to resize now is Paint.net.

Problem I run into is after resizing is: the in game resulting textures are black.

If I look at resized texture, the RGB values are off and all HSV values are all ZEROED. Which explains the black.

I am no texture editing expert and I'm a bit stuck on it.

Can anyone help me out on how to correctly resize these texture correctly? Or which tool works best?

Note: I will not use half res texture setting. Only a several 2048x/4096x textures cause the high mem usage.

I did had them resized to 50%, before I notice the alpha channel issue and the KSP memory usage was lowered quite significantly.

Try the Gimp. http://www.gimp.org/

Thanks, I just did and found out that interpolation in Pain.net was at fault. Gimp has the option for none and that works perfect ±'
