Beyond a Steel Sky
« on: July 17, 2020, 22:23 »
Game: Beyond a Steel Sky (steam page)
UE4 version: 4.26 (latest version), 4.24 (previous versions)

Meshes and textures works fine with the latest umodel build (1314 at the moment). Animations doesn't work in official builds due to ACL compression, thanks to Gildor for confirmation.

Update: Starting from version 1.3, the game is using zstd compression, unsupported by umodel. Use corresponding quickbms script from here to extract assets (4.25 or 4.27, depending on game version).
Update 2: They've switched to 4.26 in the latest update. Also, you can now use specific umodel build (download) with zstd compression support to view assets directly from pak without extracting them.

Update 3: Animations are now mostly supported with ACL 1.3 build from this topic, though you need to extract assets first, because zstd compression is not supported there, like in official builds (support will be added later). Also batch operations for animations may fail, as there are too much animations in the game - simply add them manually via "append" option.

Yeah i get exactly the same error too, i wonder why it shows animations support on the compatibility table though, perhaps just objets animations are supported?

Animations doesn't work, probably due to custom format - there is error "wrong CompressedTrackOffsets size (has 0, expected xxx)" for every animation sequence which umodel is trying to load (example asset).
Checked the file. Unfortunately the provided data is not enough: there's just an AnimSequence which is nothing without Skeleton. So, it would be great to have a mesh, skeleton and animations.

@Gildor: Sorry, I didn't know which assets will be required. Updated samples in the first post.

Checked the file. It has custom animation compression system. I think it uses ACL.

Yes, I've found references to ACL UE4 plugin in resources. I guess there is no point in implementing support for it at the moment, unless some big game will use it. Thanks for the check )

Yes, exactly!

Despite BTSS is a classic game, I started my PC gaming with playing its predecessor (and I loved the game) - I wouldn't like to implement ACL unless this will really be needed.

The game is using 4.26 in the latest update (it still works fine with everything, except animations). Also, I've added specific umodel build with zstd compression support to the first post. If you'll bump into compression related errors with that build, please let me know.

Apparently the ACL animation tool from Akderebur in https://forum.xentax.com/viewtopic.php?f=16&t=24009 after the update that supports Life is Strange 2 episodes 4-5 also made support for this game even tough it's not mentioned there, altough i could only test the older version of the game (ue 4.24) so that one has working animations now using that tool, even tough i havent done much testing, but the humanoid characters are working so far, and even a robot i test. Unsure if the ue 4.26 version works or not, if somebody could test that it would be great.

Most animations for the game are now supported with experimental umodel build, read the first post (update 3) for more info and current limitations.
