The processing related to WindDirection in AnimDynamics( in FAnimNode_AnimDynamics::PreUpdate ) does not consider other than ComponentSpace.

// Setup wind data
Body->bWindEnabled = true;
Scene->GetWindParameters_GameThread(SkelComp->GetComponentTransform().TransformPosition(Body->Pose.Position), Body->WindData.WindDirection, Body->WindData.WindSpeed, WindMinGust, WindMaxGust);
Body->WindData.WindDirection = SkelComp->GetComponentTransform().Inverse().TransformVector(Body->WindData.WindDirection);
Body->WindData.WindAdaption = FMath::FRandRange(0.0f, 2.0f);
Body->WindData.BodyWindScale = WindScale;

For example, in the case of WorldSpace, the above WindDirection conversion process is unnecessary.

Steps to Reproduce
  1. Place a SkeletalMesh that uses AnimDynamics with Simulation Spece set to something other than Component(ex.World) and Wind enabled.
  2. Place WindDirectionSource
  3. PIE

expect : AnimDynamics  reflect Wind direction
result : AnimDynamics does not accurately reflect the wind direction.For example, changing the orientation of the actor makes it easier to understand.
