Tera terrain/world extraction

« on: May 15, 2013, 20:22 »

Hey guys,

i want to extract the terrain from tera (ue3 based game), it looks like the stuff is stored in ".gmp" files. those files are normal ue3-packages (can be extracted with gildors extraction tool)

but now i want to create a merged view of all the terrain, with all the objects (for example trees or rocks, etc.) on it.

this might could look like this when it's done:
http://cotdp.com/wp-content/uploads/2012/09/RedcastDemo_Northshire_Abbey1.png

(Screenshot taken from WoW, same requirements, but other file formats of course)

i think the correct term of what i wanna do is to "extract the level" of the game (i am not quite sure since i am not a native english speaker Tongue

)

i also think some of the information i search might be stored in the "TheWorld\PersistentLevel.Level" file within the "gmp"-archieves...

maybe somebody knows how to archive this,
i would be pleased with any help

thank you very much & i apologize for my crappy english Roll Eyes

Hm, I did something similar with lineage2 by using dx ripper to capture an entire scene. Dont know if it works with tera though

I'd suggest you to look at the ME3 Explorer project. I think it's only the project for the moment which has level viewing capabilities.

hi again

@teoma since ninja ripper works the same way as 3d ripper dx, it is not working for me neither, but thanks anyway

@gildor... thanks one greate tip, but i am stucking in some trouble with ME3Explorer:
ME3 Explorer only works with lowVers == 684 && highVers == 194... unfortunally the tera packages have lowVers == 610 and highVers = 14 (so the format is older i guess)

i tried to ignore the version check, but its definitly not working that way... there is something wrong about the blockCount... i read that some tera packages may be obfuscated? is this true, and do you may know how to deobfuscate them?

would be great if you could help me...

thanks

by the way... is your extractor tool or umodel open source Huh?

if it was i would be able to combine your source for extracting the packages with the me3-explorer-level-viewing stuff to archieve what i want...

if you have some sample files I can have a look into it. as a starting project you could use this and modefy it (its big endian for xbox, just use normal bitconverter class for pc): http://www.gildor.org/smf/index.php/topic,1794.msg14258.html#msg14258

sure i have some example files...

http://dfiles.eu/files/2e647ub4m (for legality reasons there is a password on the file, which i will pm to everybody interested...)

i also tried out the tool you wrote for injustice... (of course i changed the code to work for little endian...) but seems not working anyway, there have to bee some small file format differences...

wow nice thank you very much

i think the namecount can be fixed that way (taken from another post from gildor):

^{public static void Init()
{
header.NameCount = GetInt(0x19);
header.NameOffset = GetInt(0x1D);

header.NameCount -= header.NameOffset;
[...]}

It seems your right, header.NameCount -= header.NameOffset; it's the fix
