- Changelogs
-
-
Version 7.0 BETA
- Note: More detailed info will be added after stable release
- Integral rewrite of the code, fixing numerous bugs
- Added a patterns system. Patterns allow files with different names to have different settings
- Profiles are no longer game-agnostic. This means appropriate actions can be taken for each game
- Added the ability to process BSAs directly in memory, resulting in faster processing and no more useless writes to the disk
- Full UI overhaul, with different levels ranging from "quick auto port" to "advanced mode"
- The log and progress windows have been ravamped
- Landscape textures are now being added an alpha channel
- Fully support FNV (thanks to the effort of Pr0bability)
- Improvements to texture processing algorithms
-
Version 5.3.15
- [Meshes] Update nifly (Nif Optimizer) to 3.2.0
-
Version 5.3.14
- [General] Update external libraries. This might fix some extremely rare bugs
- NOTE: as I was unable to reproduce the bug reported by Feles Noctis, it is unknown if it is fixed. Remember to always backup your files
-
Version 5.3.13
- [BSA] Do not pack dialogueviews. Apparently, packing them makes mods harder to translate. This can be reverted by editing FilesToNotPack
- [BSA] Improve merging. Sometimes, only one BSA will be created when two would have been created previously
- [BSA] Give priority to loose files when unpacking
- [bsa] Allow ".hkp" file extension
- [NIF] Fix a crash when processing "dirty" meshes (root index != 0)
- [Meshes] Fix exception with UTF8 texture paths
-
Version 5.3.12
- [FO4][BSA] Fix a bug (in a 3rd party library) resulting in BA2s never being compressed. Unfortunately, due to a Bethesda bug, uncompressed textures BA2 result in infinite loading screen. You will thus need to repack the textures BA2 made by 5.3.11. You can check if a BA2 is compressed using bsarch
-
Version 5.3.11
- [BSA] Fix BSA "delete backup" not working
-
Version 5.3.10
- [BSA] Ignore "readme.txt" instead of "readme". This means files with names such as "MeshReadMerry.psc" won't be ignored anymore
- [BSA][FO4] Conform more strictly to Archive2 behavior when packing cubemaps. This does not appear to have any impact on the game
- [BSA] Add ".hkb" to allowed file types
- [NIF] Add more detailed optimization log (when verbose log is enabled)
-
Version 5.3.9
- [BSA][FO4] Fix cubemap extraction. Note that the behavior is not the same as archive2: archive2 does not write the right file header
-
Version 5.3.8
- [BSA] Fix rare issue with dummy plugin naming
- [BSA] Fix dummy plugin creation for LE
- [NIF] Update to NifOpt 3.1.0
-
Version 5.3.7
- [FO4][BSA] Should fix textures BA2 packing
-
Version 5.3.6
- [BSA] Fix a crash when extracting archives with flags "embedded file names" and "share binary data"
- [Textures] Fix a performance issue with compress : CAO took much more time when this option was enabled
-
Version 5.3.5
- [BSA][FO4] Hopefully fix infinite load screen. (The fix has been confirmed to be working by one user at least)
- [BSA] Fix FilesToNotPack.txt working inacurately
-
Version 5.3.4
- Fix file extensions being compared case-sensitively
-
Version 5.3.3

-
Version 5.3.2
- [GUI] Small changes to BSA tab
- [BSA] Slightly increase maximum BSA size
-
Version 5.3.1b

Version 5.1.2

-
Version 5.0.8
- [Textures] Hopefully fixed a bug reported with 5.0.7, which corrupted all processed textures. Since I could not reproduce it, I advise to test this version before using it
-
Version 5.0.7
- [BSA] Fixed a bug that caused CAO to crash when packing very large folder (e.g 3DNPC)

Version 5.0.2
- [Animations] Fixed a bug that could delete the processed animations in some cases. I'd recommend to reinstall all the animations mods that were processed with the previous version, apologies for the inconvenience.
- [BSA] Fixed a bug that made the process ignore FilesToNotPack.txt, thus packing animations
-
Version 5.0.1

- [BSA] For SSE and FO4, the dummy plugin used to load BSAs is now a ESP-FE (esp flagged as esl)
