Help with DDS files

[Cthorthu]

Hello

 

Usually, I like to edit DDS images from vanilla game and from mods for personal use retextures. In most cases I can do it (I use photoshop DDS plugin).

 

But sometimes I can't. There is a "type" of DDS images that I cannot edit. This type of files have no icon in windows folder. Photoshop can't open this images (format issues).

 

Also, GIMP can open this images, but the result is not good (I open the image, export a copy of that image, replace original image: the result on the NIF model is not the original).

 

I think there is a lack of data of alpha channel or something similar. But I tried to do many test editing the alpha channel and have no good results. This causes a problem with specular and normal maps.

 

I tried DDS Converter 2, but have no good results :tongue:

 

Can you help me? What program can I use?

 

 

Thank you for reading

And excuse my poor english

Have a nice day

Maybe these textures are BC7 compressed. If you use Photoshop, download Intel Texture Works (https://software.intel.com/en-us/articles/intel-texture-works-plugin). It's probably the only plugin for PS that can read those files. Some mod authors use this format as it's the same size as DXT5 but better quality.

Just adding this here. If Photoshop is out of reach, you can use Microsoft's texconv.exe and convert the BC7 to DTX5, open the DTX5 texture in Gimp. Just use texconv if you need to export the result as BC7 again.

Hi everyone :) .

I dont find the button to download Texconv, and after downloading it, what will be the command to put ?

Will we have to separate the mipmapthing ?

Thx

The base command is probably :

texconv.exe -f DXT5 tricentennialx1arm_d.dds

pause

But... I have a doubt.

All I need if this damned file >< ...

I found the last "Texconv.exe", I tried on the Define Map, and... The texture is now all black :

texconv.exe -y -f DXT5 tricentennialx1arm_d.dds

pause

But nothing ingame, maybe I have to do it on the normal map only ?

EDIT : No, still nothing with the normal map in DXT5... But the texture is not all black this time, it didnt change of color, only in "shape" (cant explain or publish a screen, this forum is a bit limited about that :'( ...).
