BA2 Upgrader – Upgrade to Ba2 Version 3
This tool can upgrade previous texture BA2 to newer high-performance textures BA2 (Version 3).
Starfield uses the new format BA2(version 2, and version 3)
version 1:
Fallout4, Fallout76, etc. *BA2 created by Archive2.exe.
version 2:
Same compression/decompression as Version 1. *used for Textures not requiring performance, non-texture datas, etc.
version 3: Faster decompression when texture transfering to video memory.since the tool to create new BA2 (Ver.2 and 3) is not yet available, I have created a tool to upgrade the previous BA2 (Ver.1) to the new Ver2 and Ver3.
please use it as a “bridge” until Bethesda releases a new archiver or someone else creates. 🙂
Possible upgrade:
Ver.1 -> Ver.2
Ver.1 -> Ver.3 *(texture BA2 only)
Ver.2 -> Ver.3 *(texture BA2 only)
NOTE:
* only Texture BA2(Ver.1 or Ver.2) can be upgraded to Version 3.
* BA2 file size will be larger when upgrading to Version 3, because of the emphasis on decompression speed in tuning.
