@quaternius @SplineMr I'm updating ozz-animation samples to use these animations. Great animations and cool mesh, it looks great! Thanks, @quaternius, for distributing them under CCO licence.

[Guillaume Blanc @jozz_sc]

@SheriefFYI Thanks. That was interesting to do. Mostly tooling and sample code as all the low level was already available.

The final piece of the puzzle: root motion blending.
The API reuses the recipe of animation blending job, to interpolate n layers of motion.

Root motion blending sample can now be tested in your browser👇

Sorry mate, I had to find a way to keep you around.
Try motion accumulation sample in your browser👇

@tamat I think it can't be at the same time indeed. When animation driven, physic solves collisions but do not drive the character.

[Guillaume Blanc @jozz_sc]

After years looping in-place, root motion extraction finally allows accumulating motion coming from animations.

Run Forest, run!

[Guillaume Blanc @jozz_sc]

@tamat Yes ! use ozz animation 😉. Kidding,.. What was your issue ?

[Guillaume Blanc @jozz_sc]

@SubstrataVr More generally, root motion is useful when the character moves away from the animation's origin: an attack, a jump, a dance...

[Guillaume Blanc @jozz_sc]

@SubstrataVr The two approaches (code or animation driven) are widely used. It's not obvious for a run animation that almost has a constant velocity indeed, but that would for a limping walk/run for example.

@zet23t 😂

Root motion extraction is now supported by ozz import pipeline (fbx2ozz, gltf2ozz) on feature/motion branch.
Enable it from the importer configuration (as usual): https://t.co/ACY87zhBZs

[Guillaume Blanc @jozz_sc]

@studio_galt Root motion in this example is imported from an animated joint of the skeleton. That's what the fbx2ozz or gltf2ozz importer/tooling will do too. To edit motion, you can edit the joint's animation in the DCC.

[Guillaume Blanc @jozz_sc]

I started working on root motion extraction and added a new sample to allow experimenting with extraction parameters.
Check out the sample live in your browser: https://t.co/OZ288iaMhv

I'm looking forward to hearing feedback and questions.

[Guillaume Blanc @jozz_sc]

More details about those changes added to the documentation: https://t.co/9J6JuVGNoC

ozz-animation 0.15.0 is out! The long wait was worth it: 30% better compression rate, massive runtime performance optimizations (backward reading, seeking long animations, ...) and more. https://t.co/Ckw0skE1J4. Thanks to all contributors.

[Guillaume Blanc @jozz_sc]

ozz-animation pre-release 0.15.0 is ready for testing, with 30% better compression rate and massive runtime performance optimizations https://t.co/JmLFIa0rqS. Please share your feedback.

[Guillaume Blanc @jozz_sc]

@SheriefFYI Are there interesting PR to do from your fork? Any chance to sync back to the original depot? I believe 0.15 optimizations are worth it ;)

[Guillaume Blanc @jozz_sc]

ok I may have taken a breather ;) Check out the pre release 0.15.0 for compression and runtime performance optimizations! https://t.co/Ckw0skE1J4

[Sherief, FYI @SheriefFYI]

Sadly, ozz-animation has become abandoned. It was the most promising open source game animation library I've seen, and if anyone is willing to support and improve a work I can sponsor them.

[Guillaume Blanc @jozz_sc]

@SheriefFYI So that means you ran version 0.15? Any issue or other feedback?

[Guillaume Blanc @jozz_sc]

@FlohOfWoe I could make it work, but the fix you propose is welcome indeed !

[Guillaume Blanc @jozz_sc]

I started ozz-animation to experiment with new programming practices and have fun coding.
It now has 2k+ stars, games shipped with it!
Past or present, big or small, throwaway or shipped by millions, please tell us about your project using ozz-animation: https://t.co/L46TyAtKiJ

[Guillaume Blanc @jozz_sc]

@FlohOfWoe You rock 💪
