Grey textures when importing a texture to Nifscope

[SaintSaenz]

Hi everyone. So I have a new rig and wanted to continue my modding adventure but something seemed off when importing textures to nifscope. Basically i did the usual.

-.tga from blender

-open in gimp

-put some colour

-and exporting (see images). But when choosing the texture in nifscope and incidentally appearing on screen they appear grey. I tried exporting a simple pattern (without the uvmaps) and it happenned to work, with colour. XD Maybe i'm forgetting something but i don't know what, any help would be great. THANKS

Note:

Already tried with dtx5, dtx3 and dtx1 when exporting from gimp but the same happens.
