Custom attributes

Intermediate You can import custom attributes created in modeling tools such as Maya. animated attributes. Attributes that aren’t animated can’t be imported.

1. Import custom attributes

• Import animations.
• Asset View, select the animation asset.
• Property Grid, select Import custom attributes. When the assets are built, Xenko imports the custom attributes from the FBX file.

  2. Control custom attributes with a script

  animation script. NodeName_AttributeName. For example, if you have the node myNode with the custom attribute myAttribute, use myNode_myAttribute.

  Example script

  ```csusing Xenko.Animations;using Xenko.Engine;using Xenko.Rendering;using Xenko.Audio;using Xenko.Rendering.Materials; namespace Sample{ public class HologramScript : SyncScript { public Material MyMaterial;

    private AnimationComponent animationComponent;    private AnimationProcessor animationProcessor;    public override void Start()     {         base.Start();         animationComponent = Entity.GetOrCreate<AnimationComponent>();         animationProcessor =

  ().FirstOrDefault(); }

    public override void Update()     {         if (animationProcessor == null || MyMaterial == null)             return;

  // Animation result may be Null if animation hasn’t been played yet. var animResult = animationProcessor.GetAnimationClipResult(animationComponent); if (animResult == null) return; // Read the value of the animated custom attribute: float emmisiveIntensity; unsafe { fixed (byte* structures = animResult.Data) { foreach (var channel in animResult.Channels) { if (!channel.IsUserCustomProperty) continue;

                    var structureData = (float*)(structures + channel.Offset);                     var factor = *structureData++;                     if (factor == 0.0f)                         continue;                     var value = *structureData;                     if (channel.PropertyName ==

  “myNode_myProperty”) emmisiveIntensity = value; } } } // Bind the material parameter: MyMaterial.Passes[0].Parameters.Set(MaterialKeys.EmissiveIntensity, emmisiveIntensity) } } }
