Bethesda archive 2 download

This affects normal maps in particular, so for the time being normal maps will very likely be incorrect and loose normal files will very likely not work correctly. To quote ianpatt F4SE :. Version History 0. Special Thanks ianpatt and behippo for helping with my understanding of the new formats.

Supported Games. To quote ianpatt F4SE : There are two types of ba2 archives: general, and texture. General archives can contain anything, while texture archives are optimized for storing textures. There is no significant size advantage when comparing the two, but texture archives store textures in a more intelligent way that is friendlier to the runtime texture streamer.

Those settings affect individual files stored in the archive. Only files added to the archive will have those settings taken into consideration, files already present will retain their previous compression level. Seems to be the maximal number of chunks before mipmaps are indexed individually. The exact incidence of this setting is currently unknown. Note that despite those default values, it'd seems that vanilla.

The exact incidence of this settings is currently unknown. The list of tiles is displayed on the main table. You can filter it with the text field at the top to only display specific files, either by sub-string match "Normal" radio-button , or by regular expression "Regex" radio-button.

Texture-optimized archives improve the way textures are handled by the game, optimizing performances and VRAM usage. Technicalities are Here are two quotes from ianpatt f4se, originally dumped.

The Texture BA2s are an optimized format. They do not hold complete DDS files but instead are optimized for streaming certain miplevels into the game. There are two types of ba2 archives: general, and texture.

General archives can contain anything, while texture archives are optimized for storing textures. There is no significant size advantage when comparing the two, but texture archives store textures in a more intelligent way that is friendlier to the runtime texture streamer. When reading a DDS file, finding the lower resolution textures requires seeking to, and therefore decompressing most of the file.

This is inefficient, because in most cases you will care about the lower resolution mips first, when the object is off in the distance. Texture archives store any mips higher than x in their own separate blocks, while the x and below are all in their own block.

Textures pack are often distributed as loose files, because they don't need any plugin. However, re-packing them as. Forum GameSpaces Beyond Skyrim. Fallout New Vegas. Skyrim Legendary Edition.
