blendtable <blendtable> { [...] }
Loads a blend table from a raw image file.
The image file MUST contain a 256 color table of its own. Each pixel will have their matching color in the table converted in the blend table.
A single image file may contain multiple base palettes, and offset can used to locate it.
ID 0 is reserved for the base game's original table of 33% transparency.
A package for Duke Nukem 3D with blend tables generated to the same specification as Ion Fury is available and permitted for use in projects with credit to the author: File:Duke3d blend package.7z
