Unpack minikit .big files with quickbms and ea_big4.bms. Four files appear in output folder. Add the file extension .rx2 to rw4xb2 files (file 2 in j0_00001.big and file 3 in j0_00005.big) and use the Fifa 08 script in attachment. This script works also the kit textures that you uploaded before. I can't update my NHL script for these files because it cause problem with NHL stadium files so better to have a different script for different games.
Beedy, is it possible to export model from rx2 file?
My advice would be to learn how to use 3D model researcher to get the models.
There is a HUGE amount of different types of renderware packaging formats for the 3D models inside rx2 archives, so making a script that works for all types would be very very time consuming.
But with some experience with 3D model researcher, you can export any 3D models you want.
Maybe, in the future, if either Beedy or me takes the time to list every single type of renderware4 3D model header ID, then we could automate the process, but for now, I would say to use 3D model researcher when Beedy's scripts don't work.
