BC5 / ATI2 / 3Dc DDS

[Nadeox1]

Hello XnView forum,

Long time user of this wonderful software.
Sometimes I have to deal with some specific formats of DDS textures, in particular normals maps saved with BC5 / 3Dc compression.
Unfortunately it seems that the software is not able to open them: Open > "Error, the file cannot be loaded".

Is support for this kind format missing?

Attached is an example texture (3Dc - Saved from Photoshop using the Nvidia Plugin)
