MakeMegaTexture (console command)
From modwiki
NOTE: Megatexture functionality is broken in the stock versions of Doom 3, Quake 4, and Prey due to a missing fragment program, megatexture.vfp. However, with a suitable replacement, the information documented in this article is still applicable.
At present, you can find a mod that provides you with the necessary file here.
Description
This command generates a MegaTexture.
Usage
At the console type...
makemegatexture [Filename]
Parameters
[Filename] - Name of .TGA file (without the extension).
Notes
This command will take a .TGA file present in the \megatexture folder and generate a new texture with four components named <filename>_preview.tga and a <filename>.MEGA file. This console command seems to be not entirely functional in Doom 3.
