NWN Crunch - Enhanced Edition

NWN crunch is a command line tool for texture compression based on https://github.com/BinomialLLC/crunch (link is external) with support  for nwn dds files. A new -fileformat nwn option has been added for compression to NWNs own dds format.

Supported formats include bmp, png, tga, dds (both standard and nwn), ktx and crn, both for input and output. Runlength encoded tga files are supported, no need for the tga flipper. You can also control the number of generated mipmaps. Call crunch without any options to see a list of command line parameters.

Batch/shell scripts for the most common operations are included. This version is set up to convert the input file to standard DDS format. These textures will only with NWN:EE.  Please refer to the included readme.

For a 1.69 version see https://neverwintervault.org/project/nwn1/other/tool/nwn-crunch (set up to compress to NWNs own dds format)
