SkelController not updating offscreen (SkelControlSingleBone vs SkelControlLookAt)

[dmitryshm]

I used SkelControlLookAt.DesiredTargetLocation in Actor.TickSkelControl and it worked. I refused to set SkelControlLookAt data in AnimTree editor and handled everything in the UnrealScript code.

Possibly the 'PhysicsWeight=1.0'

No. I've set 'PhysicsWeight=0.5' but nothing changed.

Possibly the 'PhysicsWeight=1.0'

SkelControlLookAt + PhysAsset = not working code

I've got the same error. It happens when I set PhysAsset. And everything works without PhysAsset.

So here's not working code.

class LadderComplexCyls extends Actor placeable;

var SkeletalMeshComponent MyMesh;                               

simulated event PostBeginPlay()
{
	super.PostBeginPlay();
	MyMesh.WakeRigidBody();
}

DefaultProperties
{
	begin object class=SkeletalMeshComponent name=FE_LadderCyls
		SkeletalMesh=SkeletalMesh'ComplexCyls.Meshes.complex_cyls_2'
		PhysicsAsset=PhysicsAsset'ComplexCyls.Physics.complex_cyls_2_Physics'
		AnimTreeTemplate=AnimTree'ComplexCyls.Animations.complex_cyls_2_AnimTree'
		PhysicsWeight=1.0
		RBChannel=RBCC_Pawn
		RBCollideWithChannels=(Default=TRUE,Pawn=false, Vehicle=false, Untitled3=false, BlockingVolume=true)
		bHasPhysicsAssetInstance=true
		BlockRigidBody=true
		bUpdateSkelWhenNotRendered=true
		bIgnoreControllersWhenNotRendered=false
	end object

	CollisionComponent=FE_LadderCyls
	MyMesh=FE_LadderCyls
	Components.Add(FE_LadderCyls)

	CollisionType = COLLIDE_BlockAll
	Physics=PHYS_RigidBody
	bStatic=false

	bCollideActors=true
	bCollideWorld=true
	bBlockActors=true
	bWorldGeometry=false    
	bNetInitialRotation=true
	TickGroup=TG_PostAsyncWork
}

And here's the working code.

class LadderComplexCyls extends Actor placeable;

var SkeletalMeshComponent MyMesh;                               

simulated event PostBeginPlay()
{
	super.PostBeginPlay();
	// MyMesh.WakeRigidBody();
}

DefaultProperties
{
	begin object class=SkeletalMeshComponent name=FE_LadderCyls
		SkeletalMesh=SkeletalMesh'ComplexCyls.Meshes.complex_cyls_2'
		// PhysicsAsset=PhysicsAsset'ComplexCyls.Physics.complex_cyls_2_Physics'
		AnimTreeTemplate=AnimTree'ComplexCyls.Animations.complex_cyls_2_AnimTree'
		// PhysicsWeight=1.0
		// RBChannel=RBCC_Pawn
		// RBCollideWithChannels=(Default=TRUE,Pawn=false, Vehicle=false, Untitled3=false, BlockingVolume=true)
		// bHasPhysicsAssetInstance=true
		// BlockRigidBody=true
		bUpdateSkelWhenNotRendered=true
		bIgnoreControllersWhenNotRendered=false
	end object

	CollisionComponent=FE_LadderCyls
	MyMesh=FE_LadderCyls
	Components.Add(FE_LadderCyls)

	CollisionType = COLLIDE_BlockAll
	// Physics=PHYS_RigidBody
	bStatic=false

	bCollideActors=true
	bCollideWorld=true
	bBlockActors=true
	bWorldGeometry=false    
	bNetInitialRotation=true
	TickGroup=TG_PostAsyncWork
}

Thx, but this did not resolve the problem. The SkelControlLookAt wont interpolate TargetLocation if the actor is offscreen, in contrast to the SkelControlSingleBone.

I will just fill in a bug report and see what epic says.

You might want to try

		bUpdateSkelWhenNotRendered=true

as well? It helped me in a similar situation...

SkelControlBase.uc

/**
 *	whether this control should be ignored if the SkeletalMeshComponent being composed hasn't been rendered recently
 *
 *	@note this can be forced by the SkeletalMeshComponent's bIgnoreControllersWhenNotRendered flag
 */
var(Performance)			bool			bIgnoreWhenNotRendered;

SkeletalMeshComponent.uc

/** If true, update skeleton/attachments even when our Owner has not been rendered recently
 * @note if this is false, bone information may not be accurate, so be careful setting this to false if bone info is relevant to gameplay
 * @note you can use ForceSkelUpdate() to force an update
 * @note: In the output from SHOWSKELCOMPTICKTIME you want UpdatePoseTotal to be 0 when this is FALSE for a specific component
 */
var() bool bUpdateSkelWhenNotRendered;

/** If true, do not apply any SkelControls when owner has not been rendered recently. */
var bool bIgnoreControllersWhenNotRendered;

Hi,

i have 2 custom skeletal controllers, both are in the same actor with "bIgnoreControllersWhenNotRendered=false" set and both also have "bIgnoreWhenNotRendered=false" set, but while the SkelControlSingleBone just interpolates its bone animations just fine offscreen, the SkelControlLookAt either simply don't update at all or depending on the set targetspace just jumps from target-position to target-position instantly. If the SkelControlLookAt actor becomes visible it interpolates correctly?

So whats the catch here? Just some bug or "intended" behavior and if so why is there a general "bIgnoreWhenNotRendered" if it gets ignored by some implementations.

Thx Andy
