S3TC compression on those textures?

Post by **Rheini** » Tue Sep 29, 2009 9:24 pm

Could it be that these textures use the S3TC compression? I read it was introduced in DirectX 6, so it could be possible, cause Dungeon Keeper 2 was released in 1999.

S3TC has a fixed compression ratio, and those textures seem to have a variable compression ratio.

Yeah I also read that.
Anyway in the meantime I found the class that handles the textures in the code.
Gotta investigate it as soon as I have some time.

Ok, so I've been in touch with Darren Pattenden, one of the game's artists, and he tells me that the original textures were .PNG. Perhaps that helps.

Yeah I know, but the main engine textures are somehow compressed.
Here's the progress thread if anyone's interested:

Yes, therefore I have asked Darren if he remembers anything about what the programmers did to those .PNG files he created.

Good work by the way! Nice thread you got there!

Thanks for that

Artists normally don't have much insights into code internals though.
Yeah, we finally found the code for de-/compression, we "just" need to misuse the exe as a dll for our purposes

Pretty interesting, but yet complicated task.
