Kinematica: No sequence matching the query were found in the binary

Hello,

This error means there is no valid tag provided in the argument of PushConstrained() function. By valid, I mean the tag should be associated to a metric.

Can you check in the Kinematica Asset Builder window that for each LocomotionTag you can see the associated metric in the Metrics bar ? (like the metric named "Default" in the example below)

 

There is probably an issue with compressed animations in Kinematica, we will need to have a look. However, you probably should not enable compression on your animations since compression is lossy and anyway Kinematica will store uncompressed poses in the binary (Kinematica will use its own compression later).

I am still curious about why the clip duration shown in the builder is about twice as long as the real clip duration. I notice you seems to have added twice the same clip in the builder, is it true ? if yes that might explain the issue.

 

Ok, would it be possible to DM me this animation (or animation that you have this issue with) by any chance (if it's not secret material of course) ?

 

Ok, this is indeed an issue in our code, I will fix it in the next release of Kinematica. Meanwhile, you can fix it locally by remplacing the function ComputeAccurateClipDuration in Editor\Utilities\Utility.cs of Kinematica package by this one :

Sorry for the inconvenience !

Code (CSharp):

1.         // Unity AnimationClip can have inaccurate length when the clip is pretty long (noticeable for clip > 5 mins)
2.         internal static float ComputeAccurateClipDuration(AnimationClip clip)
3.         {
4.             ModelImporter modelImporter = ModelImporter.GetAtPath(AssetDatabase.GetAssetPath(clip)) as ModelImporter;
5.             if (modelImporter.animationCompression != ModelImporterAnimationCompression.Off)
6.             {
7.                 Debug.Log($"Animation clip {AssetDatabase.GetAssetPath(clip)} has compression enabled, it's better to not use animation compression since it's lossy and Kinematica will uncompress animations anyway.");
8.                 return clip.length;
9.             }
10.  
11.             var bindings = AnimationUtility.GetCurveBindings(clip);
12.  
13.             float frameDeltaTime = 1.0f / clip.frameRate;
14.  
15.             int maxNumKeys = 0;
16.             foreach (EditorCurveBinding binding in bindings)
17.             {
18.                 AnimationCurve curve = AnimationUtility.GetEditorCurve(clip, binding);
19.                 int numKeys = curve.keys.Length;
20.  
21.                 if (numKeys > 1)
22.                 {
23.                     float firstDeltaTime = curve.keys[1].value - curve.keys[0].value;
24.                     if (!Unity.Mathematics.Missing.equalEps(firstDeltaTime, frameDeltaTime, 1e-4f))
25.                     {
26.                         continue;
27.                     }
28.                 }
29.  
30.                 maxNumKeys = Mathf.Max(numKeys, maxNumKeys);
31.             }
32.  
33.             int numFrames = maxNumKeys - 1;
34.             if (numFrames <= 0)
35.             {
36.                 return clip.length;
37.             }
38.  
39.             return numFrames / clip.frameRate;
40.         }

 

Hello, when you try to preview your animation with Kinematica Asset Builder window, can you confirm you see a correct trajectory like the example below ?



You should see past and future trajectory from character root

 

Unfortunately the issue is due to Kinematica currently not supporting hierarchies where the first body joint (Pelvis_def) is not the first direct child of character root (HalfStep_straight_01_01).



Sorry about that, we should have made it explicit, and we will remove that limitation in the near future. Meanwhile you can fix that by either changing the hierarchy of your character in your FBX by making sure Pelvis_def is the first child :


Or your can change bodyJointIndex to 3 in AnimationRig.cs line 27

Sorry for the inconvenience !

 

Hello, sorry for the trouble you have, would mind sending me in DM you newly configured rig please ?

 

Just got your latest rig, it's better but an issue remains actually :


The Pelvis joint is the second child whereas it should be the first (maybe you can rename LibraryDude_mesh as I think joints are sorted by alphabetical order)

Sorry for the inconvenience

 

We will fix that for next drop of Kinematica which will be released soon. This drop should be able to pick the right root joint you setup in your Avatar without needing any specific organisation of your joints. I tried it with your rig and it seems to works as expected :

 

Hello FYI we just released the 0.7.0-preview which contains the fix I mentionned : Unite Now - Kinematica – Democratizing Motion Matching for Character Animation

Please don't hesitate to post a message if you have any other issue
