Why do I get the alembic plugin error

Hello all,

I’ve made a model of .abc extension and imported to unity using alembic plugin “AlembicForUnity.unitypackage”

I’ve imported the model and got this error:
transform.localScale assign attempt for ‘Cylinder223’ is not valid. Input localScale is { 0.000000, NaN, 0.000000 }.

This is the script:

using UnityEngine;

namespace UTJ.Alembic
{
    public class AlembicXform : AlembicElement
    {
        aiXform m_abcSchema;
        aiXformData m_abcData;

        public override aiSchema abcSchema { get { return m_abcSchema; } }
        public override bool visibility { get { return m_abcData.visibility; } }

        public override void AbcSetup(aiObject abcObj, aiSchema abcSchema)
        {
            base.AbcSetup(abcObj, abcSchema);

            m_abcSchema = (aiXform)abcSchema;
        }

        public override void AbcSyncDataEnd()
        {
            if (!m_abcSchema.schema.isDataUpdated)
                return;

            m_abcSchema.sample.GetData(ref m_abcData);

            if (abcTreeNode.stream.streamDescriptor.settings.importVisibility)
                abcTreeNode.gameObject.SetActive(m_abcData.visibility);

            var trans = abcTreeNode.gameObject.GetComponent<Transform>();
            if (m_abcData.inherits)
            {
                trans.localPosition = m_abcData.translation;
                trans.localRotation = m_abcData.rotation;
                trans.localScale = m_abcData.scale;  //<-----------this is where the error is
            }
            else
            {
                trans.position = m_abcData.translation;
                trans.rotation = m_abcData.rotation;
                trans.localScale = m_abcData.scale;
            }
        }
    }
}

Does anyone familiar with this issue?

I’ve found the solution:

Apparently in Unity you shouldn’t give the child and the parent the same name.

When renaming the parents game objects by mistake, the errors disappeared.
