Support for DDS-files with 3DC-compression

[Modder]

Hi all,

As a modder (with CryENGINE) i regularly need to view and manipulate DDS-files. For normal maps, DDS-files are compressed with 3DC algorithm, which XnView is unable to handle.

Currently only choice for me to view these files outside Sandbox-editor is GIMP with DDS-plugin, which is good but a bit too heavy for viewing. Would be great to have 3DC implemented in XnView, which otherwise is an excellent tool.

could you send me some samples?

Couple of files zipped in attachment..

3DC compressed dds-files can be created in GIMP by applying filter "Normalmap", setting "DU/DV map" as "8 bits (unsigned)" and saving as .dds with "BC5 / ATI2" compression with mipmaps. Cranking up "Scale" in normalmap settings will give stronger effect.
