When using indexed hightiles you don't have to supply separate palette variants for each image, they are instead recolored in-engine.įor most palette swaps, either the whole palette is tinted uniformly excluding fullbrights or just palette indices 64-95. Once you’ve made your upscales you need to define them in a DEF file. You will also notice the lack of transparency. They will be in TGA format so you will want to use the image processing tool of your choice to convert it to a format supported by ESRGAN. This will extract all the art files in the folder you run it in. If you have many ART files to work with, a more convenient approach though is with a batch script To resolve this, place the file PALETTE.DAT from your game in the same directory as ART2TGA. However you may find the palette comes out wrong. You can extract an ART file by dragging it onto the executable. Instead, my preferred method is a commandline tool called ART2TGA. The downside is the exported tiles no longer retains the original color indices, which we’ll get to later. This may be more user friendly for the novice user and the resulting exported file will have transparency already applied. Your first task is to extract tiles from the games ART files, for some games the ART files are already in the game’s main folder (Blood, Witchaven, TekWar) for others they are stored inside a GRP file (in case of Powerslave it is called STUFF.DAT but programs that support GRP files will also open that although you may need to change the file extension) which can be extracted by several tools, for example SLADE.ĪRT files can be opened in M210’s BAFED, which is preconfigured with palettes for most Build Engine games. This will not work on NightDive’s Blood Fresh Supply. Note that everything on this page assumes you are using either an Eduke32 or BuildGDX-derived port.
