Textures Modding

« on: June 01, 2012, 12:25 »

Hi
I'm working on reskinning some characters from couple of UE games.
I managed to hex edit almost any texture in .upk files.(of course after decompression)
But the problem is they're not the main textures and the real ones are in .tfc files.
My question is has anybody ever hex edited any texture in .tfc fles?
Cause it seems .tfc files can not be decompressed so no hex editing.
Thanks

my tool reads the references for ME3s pcc files, they come right after the properties, maybe you can copy that behaviour. Just google ME3Explorer

I can't find out how your tool can help me.
I need to decompress textures.tfc.
Your tool can extract bink movies from movies.tfc though.
btw,great tool.

the tfc is just a big pile of compressed chunks, which contains the textures in compressed blocks. they all start with a magic number, you could scan for them, but thats unreliable as it could occur in the data too. In the pccs are the offsets saved where these chunks begin, then you need to read the header at this position (16bytes) and all block headers(each 8byte). After that follows the compressed blocks one after another and you need to decompress them with zlib. After that you have to recombine them and add an dds or tga header so you can view it in a picture program. all this is done in my programs code, just search for it, most work is done in the unreal helper section.
