If I use DirectorUpdateMode.Manual, how can I change rig weight？

[fleity]

Welcome to a whole world of pain.

I have been working with a similar setup for the past 6 months and every few weeks this comes around to really really cause a lot of pain (either animation or rigging not working at all or like right now complete crashes of the engine).

As far as I can reconstruct it, if you manually evaluate the playable graph you are breaking the interleaving (and threading!) of rigbuilder and animator which causes one of both to write their default values while the other one has already cached their values for the current frame.
If you let unity just handle this they magically make this work as

“If by Evaluate() you mean PlayableDirector.Evaluate() or PlayableGraph.Evaluate(), then no. Those are intended to be synchronous evaluations of a graph. When a graph is playing however, Evaluate() isn’t called. Those phases are split up and run at different points in the PlayerLoop (but all between Update() & LateUpdate()), and threaded as appropriate.”

PlayableGraph Evaluate performance/best practices

1. I've read calling Update manually on an Animator " means your animators will run single-threaded ". How much of the cost of an Animator update comes from the graph evaluation? Is calling Evaluate on a playable graph with Animation Outputs essentially equally expensive? Yes - Update() (or PlayableDirector.Evaluate()) evaluates the entire graph single threaded, and that is where most of the cost is. An animator controller is a playable graph, as is timeline and the evaluate does a prepare (up…

I have a collection of threads dealing with parts of similar problems if you are interested, maybe some of the posts will help you figure out how to work around your problem.

Execute code after the animator update but before constraints are applied

For foot IK you're supposed to raycast to the current foot position and adjust the IK target/weight accordingly. Tried using LateUpdate, but constraints are applied before the LateUpdate. What to do?

Bug? Possible conflict between RigBuilder and sequences

Reporting in case a problem with sequences beta - not sure. I use "RigBuilder" from Animation Rigging 1.0.3 (Unity package to allow you to do overrides in a timeline, https://docs.unity3d.com/Packages/com.unity.animation.rigging@0.2/manual/index.html). But as I flip around my scene with sequences, I am seeing the error below in the log. I am wondering if jumping between timelines is getting it confused [7285174--880927--upload_2021-6-30_1-14-31.png] The stack trace is MissingReferenceExcep…

Animation Rigging with Multiple Animator Layers

Hello, I am experimenting with the Animation Rigging package to use it in my game. The main player has an animator controller with multiple layers: [7248203--873308--upload_2021-6-17_15-17-57.png] When I applied the Rig setup to the player, added one IK constraint, and started playing the game, many things began to act strangely. For example, the IK target and hint are both snapped to the origin, the Rig weight is stuck at 1 (cannot be changed), and so on. I checked with the official documen…

If you want to go this route of manually updating you probably need to build the rig graph into the animator graph using
m_RigBuilder.Build(animator.playableGraph)

but be warned this crashes the editor for me when disabling and reenabling the character. All in all I would recommend you to just stay away from fiddling with Rigbuilder.Build and manual update mode completely, just let the engine do it’s thing, set everything to update as normal in solve your setup some other way.
