Yes must be about correct. There are different YUV to RGB variants, need to choose one.

This one is from Doom. But must work similar with other ID games.

But what about id Tech 4 games? From what I`ve heard, some of these games using that engine used Megatextures as well.

Id Tech 4 was the engine used for Doom 3. But at that time, it was only used for the map environment. Models and Characters still used traditional textures. So it's not applicable. With Tech 5, they expanded megatexture to Characters and Objects. Which is the problem being addressed here.

Yeah but at the time the MegaTexture concept did not exist until Enemy Territory Quake Wars came in.

according to Wikipedia:
Brink, which uses a heavily modified version of id Tech 4 also uses virtual texturing. While the implementation is different from MegaTexture, it was inspired by it.
So yeah that would probably be a whole other kettle of fish :)

Of course Wikipedia is often wrong, like where they say:
All id Tech 5 and id Tech 6 games use MegaTexture, with the exception of The Evil Within which uses a new renderer.
Wrong. it's just a different encoding. Still uses MegaTexture. :mrgreen:

if I remember, there is a command for Brink that allows to dump all textures as a big tile

Great work! I'm glad to see someone conquer Megatextures for Doom
