Raycast from IAnimationJob.ProcessAnimation()

I’m trying to write an animation job that performs foot-fixup against terrain as part of a PlayableGraph. However, both Physics.Raycast() and RaycastCommand.ScheduleBatch() complain about not being on the main thread.

What’s the correct way to raycast from the playable thread? If not, is there a way to synchronize with the main thread? Or else, what’s the best place to request support, since this would be a high-value feature for a number of animation problems.

Point of clarification: the foot location that we’re querying-from is coming from the AnimationStream itself – we’re adjusting the incoming animation-pose with ik, so the position isn’t known before the playable-graph kicks-off evaluation.

Attempting to use PlayableBehaviour.ProcessFrame() as a hook appears to be no-bueno, since it’s attached to an AnimationPlayableOutput rather than a ScriptPlayableOutput, and therefore doesn’t run.

For reference, here’s the log from attempting to raycast through the job system.
