SkeletalMeshComponentのDetailsにあるAnimationModeを
UseAnimationAssetからUseAnimationBlueprintに変更すると
AnimNode_KawaiiPhysics.cppの37行目のWorldがnullptrでハングします。

↑の状態でUseAnimationBlueprintに変更すると症状が発生します。

あまり使わない手順だと思いますが念のため報告いたします。

Have a nice day o/

We've found that large gravity parameter (z = -5000 for example) will cause bone trembling/shaking.

We wonder if anyone would have any ideas/inputs on this.

Thanks!

Here is the setup:

P.S.
I think this is what was causing the trembling:

Bone.Location += (BaseLocation - Bone.Location) *  (1.0f - FMath::Pow(1.0f - Bone.PhysicsSettings.Stiffness, Exponent));

When the FPS fluctuates, even if we stand still, we still have the simulated bone pulling in/out of bone pose location (which is given by the animation pose).

UE5 Preview 1 was released so it would be nice to have a UE5 Preview 1 version!

件名の操作を行ったとき、
UKawaiiPhysicsLimitsDataAsset::UpdateLimit()でSphericalLimitsなどに変更が入っても、UEエディタ上で
データアセットに変更を示す*マークがつきません。
これは、UKawaiiPhysicsLimitsDataAsset::UpdateLimit()内でModify()メソッドを呼べばつくようです。
（他にもいいやり方があるかもしれません）

SphereLimitに対して、LimitTypeがOuterのときは、コリジョンしたときは
ボーンとSphereLimitの球同士が吸着したような状態まで位置修正していると思います。
一方、LimitTypeがInnerのときは、コリジョンしたときはボーンの位置はSphereLimitの球の表面に位置修正され、ボーンのRadius変数が考慮されません。
Innerと聞いて私がイメージしたのが、ボーンの球がSphereLimitの球の内側に吸着するような位置修正でした。
ただ、これはあくまで個人的な仕様解釈で気になったに過ぎないので、一意見として扱っていただければ幸いです。

AnimNode_KawaiiPhysics.cppの関数
CollectChildBonesでモデルに存在しない骨も数えてしまうため
添付画像のような場合、263行目でChildBoneが１になってしまいDummyBoneが追加されないようです

BPプロジェクトの場合、エディタのLaunch、または作成したパッケージから起動した場合、Kawaii Physicsの物理が正常に動作しない。C++プロジェクトの場合は正常に動作する。

AnimNode_KawaiiPhysics.cppの重力処理が以下のようになっていました。
// Gravity
// TODO:Migrate if there are more good method (Currently copying AnimDynamics implementation)
Bone.Location += Gravity * DeltaTime;

AnimDynamicsの処理を見たとことろAnimPhysSolver.cppで以下のようになっていました。
FVector Force = InBody->bUseGravityOverride ? (InBody->GravityOverride * InBody->Mass) : (GravityDirection * FMath::Abs(UPhysicsSettings::Get()->DefaultGravityZ) * InBody->Mass * InBody->GravityScale);
InBody->LinearMomentum += Force * DeltaTime;
InBody->NextPosition = InBody->Pose.Position + InBody->LinearMomentum * InBody->InverseMass * DeltaTime;
Gravityに対してはDeltaTimeの2乗を乗算した上で位置の次元の変数に代入するような次元の扱いとなっていました。

どちらであっても、アーティストのGravityの設定次第で同じような動きが達成されると思うので、あくまで私の意見になりますが、タイムステップの2乗になっていた方が自由落下に近い動きをするときによりリアルな動きになるかもしれません。

KawaiiPhysicsを導入している4.25のプロジェクトを4.26にバージョンアップしようとした際に、

"The following modules are missing or built with a different engine version:
KawaiiPhysics
KawaiiPhysicsEd
Would you like to rebuild them now?"

と表示され、"はい"を選択しましたところ、

"〇〇〇〇 could not be compiled. Try rebuilding from source manually."

と表示され、起動できませんでした…。

この問題がKawaiiPhysicsの問題なのか、わかりませんでしたので、
この結果になった流れをお伝えさせていただきます。

最初に4.26にバージョンアップさせた際、上記のエラーが出て、
このときは、KawaiiPhysicsのバージョンが1.6.0のままでしたので、
KawaiiPhysics 1.7.0 のzipを解凍し、中身のpluginフォルダにあるKawaiiPhysicsフォルダを
作業プロジェクトのpluginフォルダにあるバージョン1.6.0のKawaiiPhysicsフォルダに上書きしました。

そして、作業プロジェクトを複製して、作業プロジェクト内の"プロジェクト名.uproject"を右クリックし、
"switch unreal engine version"を選び、4.26を選択し起動させてみたところ、
同じエラーが出て、起動ができませんでした…。

お忙しいところ恐縮ですが、
よろしくお願いします。。

FAnimNode_KawaiiPhysics::EvaluateSkeletalControl_AnyThread()の以下のコードについて指摘させてください。

if (SkelCompMoveRotation.GetAngle() > TeleportRotationThreshold * TeleportRotationThreshold)
{
	SkelCompMoveRotation = FQuat::Identity;
}

角度の比較なので、TeleportRotationThresholdは2乗する必要がないように思いましたがいかがでしょうか。
また、GetAngle()はラジアン単位で返しますので、TeleportRotationThreshold は度で設定すると思いますので、単位の変換が必要なのではないかと思いました。
今まではラジアンなので小さな値が返っていてこの分岐内に入ることがほとんどなかったのでないかと推測しています。

Hi pafuhana1213,

I'm reporting a bug here.

The bug:
When rotating my character along z axis, her hair, which is animated by kawaii, appears jittering.

The cause:
In the function SimulateModifyBones, Bone.PrevLocation is updated before its final usage, causing WorldDampingRotation to not work properly.

The fix:
This can be fixed by moving the update of Bone.PrevLocation to the end of the loop.

Regards,
Yi

Hey guys I have been trying to upgrade Kawaii Physics to 5.1 for the past couple of weeks, had to change some classes because they seem to have changed their method for source objects with TObjectPtr<>

FKawaiiPhysicsSettings PhysicsSettings;

/** Curve for adjusting the set value of physical behavior. Use rate of bone length from Root */
UPROPERTY()
TObjectPtr<UCurveFloat> LimitAngleCurve_DEPRECATED = nullptr;

Not sure if I did that right but it got rid of those issues for AnimNode_KawaiiPhysics.h

but still, have a couple more issues with something inside the editormoderegistry.h is still seeing it as an abstract class, Not sure how to fix this issue, but would like Kawaii Physics in 5.1 for our project.

I will keep debugging but here is how my last build went
I don't know how to rewrite FKawaiiPhysicseditmode so that it no longer is an abstract class

If the game is run in standalone (development build) the KawaiiPhysicsEd module will be missing and the animation blueprint will break. (log will complain about the missing module) We found the issue to be related to the module type being set to EditorNoCommandlet. The plugin is still working in PIE and release builds however.

{    "Name": "KawaiiPhysicsEd",    "Type": "EditorNoCommandlet",    "LoadingPhase": "PreDefault" }

We fixed this in our project by setting the module type to DeveloperTool. Now it works in all builds.

{    "Name": "KawaiiPhysicsEd",    "Type": "DeveloperTool",    "LoadingPhase": "PreDefault" }

We believe this is related to standalone development builds needing access to animgraphnodes for debugging.

FKawaiiPhysicsEditMode::InputKey()の実装ですが、

		else if (InKey == EKeys::Delete && IsValidSelectCollision())
		{
			switch (SelectCollisionType)
			{
			case ECollisionLimitType::Spherical:
				RuntimeNode->SphericalLimits.RemoveAt(SelectCollisionIndex);
				GraphNode->Node.SphericalLimits.RemoveAt(SelectCollisionIndex);
				break;
			case ECollisionLimitType::Capsule:
				RuntimeNode->CapsuleLimits.RemoveAt(SelectCollisionIndex);
				GraphNode->Node.CapsuleLimits.RemoveAt(SelectCollisionIndex);
				break;
			case ECollisionLimitType::Planar:
				RuntimeNode->PlanarLimits.RemoveAt(SelectCollisionIndex);
				GraphNode->Node.PlanarLimits.RemoveAt(SelectCollisionIndex);
				break;
			case ECollisionLimitType::None: break;
			default: ;
			}
		}

となっていますが、SelectCollisionIsFromDataAsset による分岐をしていないため、
SphericalLimitsDataの方にLimitがあって、そちらを選択してるときにDeleteボタンを押すと
空のSphericalLimitsに対してRemoveAt()が走り、クラッシュする、ということが起きそうです。
こちらでもSelectCollisionIsFromDataAssetによる分岐をすれば解決すると思います。

KawaiiPhysics EA Verison Not available with UE5 preview 2 version

The world damping values get run every frame, so the higher the framerate the more dampening that happens (most noticeable with long bone chains). At lower FPS it will be more bouncy, but as you increase the max FPS it becomes less bouncy and just goes straight, making the physics not look as good.
Heres a video example showing what I mean, can see it the most in the tail

I have found a possible fix but isn't the best implementation to target how it looks at a specific FPS.
This is what I did to make it consistent across all framerate unless its lower than target fps, the edit is in "AnimNode_KawaiiPhysics.cpp" (and "AnimNode_KawaiiPhysics.h" to add cumulativeDeltaTime to each bone, had issues if not all bones had their own value for some reason), for some reason though this code randomly stops working for some physics nodes, maybe because I don't know much about C++. (I tried using delta time but couldn't figure out how to get it to work well)

Currently Spherical, Capsule, Planar Limits Offset Location and Rotation can be driving only by bone.
My enhancement request is being able to set them as well in "External Force" or maybe keep it in same place. This will help to interact with the outside forces.

To show that idea I did create picture with photoshop.

Hi @pafuhana1213 ,

We are experiencing a crash in the first line of the method FKawaiiPhysicsEditMode::OnExternalNodePropertyChange.

void FKawaiiPhysicsEditMode::OnExternalNodePropertyChange(FPropertyChangedEvent& InPropertyEvent)
{
	USkeletalMeshComponent* SkelComponent = GetAnimPreviewScene().GetPreviewMeshComponent();

	if (!IsValidSelectCollision())
	{
		SelectCollisionIndex = -1;
		SelectCollisionType = ECollisionLimitType::None;
		CurWidgetMode = UE_WIDGET::EWidgetMode::WM_None;
	}
}

We have debugged the issue and it happens because the Owner does not contain a valid FAssetEditorModeManager instance.

IPersonaPreviewScene& FKawaiiPhysicsEditModeBase::GetAnimPreviewScene() const
{
	return *static_cast<IPersonaPreviewScene*>(static_cast<FAssetEditorModeManager*>(Owner)->GetPreviewScene());
}

As the variable SkelComponent is not used in the method (and the calls to to get the variable do not have side effects) we managed to fix the crash simply removing the first line.

You can reproduce the crash doing the following operations in the anim graph view:

• open animation layer asset A
• select a kawaii node N and update any property (make sure that the node is being used to compute the final pose)
• compile asset A
• close asset A
• open asset A again
• select the same kawaii node and update the same property
• compile asset A
• observe the crash

Best regards,

Sergi

I am trying to create modular parts for hair, skirts etc. At this moment all parts sharing same skeleton and also animation blueprints but setting this to "SetMasterComponent" makes kawaii plugin to do not work?

After calling ResetDynamics, all the bones reset their settings (eg. Damping, Radius, Stiffness, LimitAngle).

In FAnimNode_KawaiiPhysics::EvaluateSkeletalControl_AnyThread, the ModifyBones array is cleared, if bResetDynamics is true, but UpdatePhysicsSettingsOfModifyBones is not called, unless bUpdatePhysicsSettingsInGame is specified.
I suggest calling UpdatePhysicsSettingsOfModifyBones after the dynamics was reset.

Hello, I'm having a little trouble upgrading the plugin to version 4.27, would it be possible to update the plugin please?

they dont show up when created. closing the window and reopening makes them show up(sometimes) but they also don't update when moving, and its impossible to select them in the preview window, as seen in kawaii physics videos and tutorials.

Gives out an error when trying to pack a project in engine version 4.26. I put the plugin on a clean project.

AnimBP_ChainKawaiiPhysicsCollision1　で見られる現象ですが、
骨の位置がカプセルの**にあるので押し出し方向が決まらずに押し出されないというのがあります。
ご認識済みで、押し出し方向が勝手に決まらないように意図している仕様であればすみません。

これは、
FAnimNode_KawaiiPhysics::AdjustBySphereCollision()やFAnimNode_KawaiiPhysics::AdjustByCapsuleCollision()で
GetSafeNormal()が、0ベクトルに対しては0べクトルを返すところから来ています。
勝手な方向に押し出すのも問題ですし難しいところかと思います。
少しでもモーションしていればほぼ発生しないめりこみですし、このままの仕様でも問題ないとは思っております。

I decided to have hair and body as separate skeletal mesh. Kawaii Physics worked perfectly fine when I had my hair as part of body mesh but I can’t figure out how to add collision so that the separate hair mesh does not penetrate body mesh. The hair mesh penetrates the body mesh because the kawaii physics of the hair skeletal mesh does not have any bones that can be used as root bones of the collision capsule/plane. In AnimGraph there is an option to add additional skeletal mesh to preview scene and I can somewhat use that to draw the collision spheres but because animBP obviously doesn’t recognise them as part of the skeleton the spheres are not linked to bones and will always stay in T-pose no matter what animation is being played. Is there any way to make this work using Kawaii Physics? Any ideas would be very much appreciated. Thank you in advance!

Everything was working well with UE5 Preview 1 and Preview 2 but with the official release today, Unreal is not able to open kawaii Physics anymore. Anyone got an idea?

Limits Data Asset is not showing any kind of information in any UE5 project.
You're able to create one. Once it's open though, there is no information showing to add the Capsule/Sphere/Planar limits.

It looks like it's working properly on UE4 projects though.

[UE4 version is 4.26]
KawaiiPhysics is in my project’s plugin
How can i fixed it?
Please help me!

The bone still swing pass the limit when character move fast
if there are kinds of fake physic lock like vertical/horizontal x/y/z only
I think it will easier to adjust some move that don't need or out of the plan
thank you

Is kawaii physics not compatible with control rig? Is there any workaround? Using UE 5.02

仕様に関する質問です。
AnimBP_ChainKawaiiPhysicsCollision2を見ると、チェインが何も動いてなければ先の方のチェインはPlaneLimitに潜りっぱなしになります。

これは、FAnimNode_KawaiiPhysics::AdjustByPlanerCollisionにおいて、
FMath::SegmentPlaneIntersection(Bone.Location, Bone.PrevLocation, Planar.Plane, IntersectionPoint)
がtrueを返すときのみ押し出し処理をするというところから来ている挙動だと思います。

これは仕様として想定している挙動かどうかを伺いたいです。
ゲーム用途ですと何かのきっかけで潜ってしまっても押し出してほしいケースが多いと思いますし、
もし仮にPlaneを片面押し出しでなく両面に対して隔てる壁と捉えていれば、GetUpVector()の方向だけでなく、
逆方向にも押し出し処理がほしい感じはします。
ただ、現在の挙動の方が、KawaiiPhysicsSampleマップのようにチェインが左右に引っ張られるケースでは、潜っていたチェインがすべていきなり1フレームで飛び出すのでなく、PlaneLimitと交差したもののみ押し出されるので、急激に動くことがないというメリットはあると感じます。
なので、仕様であっても問題はなく、今回は確認させていただきたかっただけとなります。

Planar Constraintを使って、回転するボーンの方向を制限しようとしているのですが、CharacterのYawが180°回転をすると、逆向きに揺れるようになってしまいます。

動画では、ポニーテールに適用しています。

UE4.27.2
v1.9.0

//@struct FKawaiiPhysicsModifyBone
void UpdatePoseTranform(const FBoneContainer& BoneContainer, FCSPose<FCompactPose>& Pose)
{
	auto CompactPoseIndex = BoneRef.GetCompactPoseIndex(BoneContainer);
	if (CompactPoseIndex < 0)
	{
		PoseLocation = FVector::ZeroVector;
		PoseRotation = FQuat::Identity;
		PoseScale = FVector::OneVector;
		return;
	}

	auto ComponentSpaceTransform = Pose.GetComponentSpaceTransform(CompactPoseIndex);
	PoseLocation = ComponentSpaceTransform.GetLocation();
	PoseRotation = ComponentSpaceTransform.GetRotation();
	PoseScale = ComponentSpaceTransform.GetScale3D();
}

Bone motion is too large when switching LOD.
When CompactPoseIndex < 0, maybe just keeping the information saved before works well.
