What is PR's OGF Editor?
This program edits Descent 3 OGF files. These files contain many of
the graphics from Descent 3.
The Basics
Each OGF file can contain multiple images. They are called mipmaps,
and are used in the game to prevent textures from jumping about when
being viewed from a distance. Mipmaps are usually the same texture
saved at multiple sizes within one file.
This program allows the creation of mipmaps within OGF files.
Note: This version can edit Descent 3 Demo OGF files. The format
for OGF files may change when the full version of Descent 3 comes out,
which might mean that this software will no longer work with new
OGF files.
