Is this Implement a layered animation system, "a la" Unity still in the pipeline? @Popov72

[Popov72]

Yes it is :)
We still have a number of things to do, but everything's going well.

[ertugrulcetin]

Once it's done, I guess we will have some something similar like this? https://developer.playcanvas.com/user-manual/animation/anim-layer-masking/

[Popov72]

Yes, it should be pretty close to what you can find in Unity's mecanim system (layers (additive or not), state machines, different types of blend trees, etc).

Thank you for the info!

I created a separate issue for baked vertex animation performance:

#15806

I've also done away with the “Unity-style” layered system, as we'd need an editor to make it a useful addition to the library, which would require a lot of work, especially as the editor would be very different from our existing editors (nme, nge, etc), so we wouldn't be able to reuse our shared code.
