Skinned mesh renderer lags behind about sbox-issues HOT 9 CLOSED

Does the same occur if you do it in OnUpdate?

from sbox-issues.

Yes, ive tried all updates

I've now changed my system so the arms attach to the camera and the ik is to move the hand to the gun, still the same effect.

Hi,

Since this commit, i guess cause i didn't have this issue yesterday,
it looks like the GetAttachment position is now incorrect during the first tick :

I am currently investigating to find a scenario to reproduce the issue. I will edit this comment

Edit :

1. Create GameObject parented to the head bone :

var goHat = new GameObject();
goHat.SetParent( bodySkinnedModelRenderer.GetBoneObject( bodySkinnedModelRenderer.Model.Bones.AllBones.Where( x => x.Name.Equals( "head" ) ).FirstOrDefault() ));
goHat.Components.Create<MyAttachment>();

2. Create MyAttachment Component:

public class MyAttachment : Component
{
	[Property] public SkinnedModelRenderer SkinnedModelRenderer { get; set; }

	public SkinnedModelRenderer GetPlayermodel()
	{
		return GameObject.Components.GetInAncestors<SkinnedModelRenderer>();
	}

	protected override void OnStart()
	{
		base.OnStart();

		SkinnedModelRenderer ??= GameObject.Components.GetOrCreate<SkinnedModelRenderer>();

		var model = Cloud.Model( "darg/santahatprop" );
		SkinnedModelRenderer.Model = model;

		Transform.Position = GetPlayermodel().GetAttachment( "hat" ).Value.Position;
		Transform.Rotation = GetPlayermodel().GetAttachment( "hat" ).Value.Rotation;

	}

	protected override void OnUpdate()
	{
		base.OnUpdate();

		// TOGGLE COMMENT / UNCOMMENT
		//Transform.Position = GetPlayermodel().GetAttachment( "hat" ).Value.Position;
		//Transform.Rotation = GetPlayermodel().GetAttachment( "hat" ).Value.Rotation;
	}
}

3. See bug OnStart:

I made a change that should fix the first frame being wrong position.

This won't fix the OP request though. This is a chicken and egg problem, and the only way I can see to fix it would be to allow you to set IK bones to offsets from GameTransforms.

Nothing change for the sub issue (my build id : 14327656), i have created a issue in order to stop off topic for this issue : #5493

Is there a reason that the skinned mesh renderer is updating after the camera, that is the only understandable thing that is happening. I can make any normal model renderer I want follow something by setting the position and it's perfect, but as soon as I change the model renderer to a skinned renderer it lags a frame behind.

Ok strange thing happening. When I move the gun around it leaves a ghost of an arm that is perfectly connected to the gun, how I want, whilst the rest of the arm is stuck a frame behind. However, when I record it the ghosting doesn't appear in the recording. What on earth is happening.

Ok, solved the issue by using SetIK and using the correct naming for parameters in anim graph.

if ( IkRightHand.IsValid() && IkRightHand.Active ) Target.SetIk( "hand_right", IkRightHand.Transform.World ); else Target.ClearIk( "hand_right" );
