ModelImporter.clipAnimations

Description

Animation clips to split animation into. See Also: ModelImporterClipAnimation.

When you import a file for the first time clipAnimations will be always empty. If you need to populate clipAnimations before the first import you can use an AssetPostprocessor and override AssetPostprocessor.OnPreprocessAnimation.

using UnityEditor;
using UnityEngine;

public class CreateAnimationClip : AssetPostprocessor
{
    void OnPreprocessAnimation()
    {
        var modelImporter = assetImporter as ModelImporter;
        modelImporter.clipAnimations = modelImporter.defaultClipAnimations;
    }
}
