Need help with unknown rx3 texture files

[Suraka]

Hi I'm trying to mod the jersey wrinkle bump maps and i'm having some trouble editing the rx3 they are in.
The files are.
jersey_0_bnm.rx3 (the main file i'm trying to get to)
jersey_0_bnm_256.rx3 (same as above but lower quality)
jersey_0_bnm_256x2.rx3 (same as above but lower quality)
jersey_0_bnm_lod.rx3 (this one I can open with no problems but it's for far away players)
they are in data3.big and there's another ones with a 1 instead of a 0 which correspond to untucked shirts.

Here's what I know from RX3 master:
there's only one file inside
GREY 8bit ALPHA 8bit 512x512

when exported I get a png that has what I was expecting.


the thing that puzzles me is that the file size of the rx3 is 1,5MB but no 512x512 image can be that big (unless it's a psd or hdr)
so I suppose there's something else in there that neither filemaster nor Textures Editor can see.
Also i can't import any image in there, filemaster shows the new texture like it's imported but when i open the file again it's unchanged.

PS tried dragon unpacker, 7zip, even the good old EA graphics editor...

BONUS QUESTION!
is there a way to pack or unpack a rx3 manually?

thanks in advance i appreciate your attention

if you are a good hexer you know a rx3 texture is a dds file without header with some hex that describe something... if you're skilled you can extract the dds file inseide , edit and then replace.

have you tried rx3 master??

it's the one i had better results but can't successfully import. Tex Editor opens an empty file

i'm not a good hexer at all, but dragon unpacker has a feature that looks for known headers (including dds) but doesn't find anything. but it doesn't find anything in rx3 known to have dds so i wouldn't exclude ddss inside.
