Get Custom Properties from 3dsMax FBX model

An article by mgear    1 Comment

Maybe not from the fbx file itself (?), but each object can have custom properties, and Unity can read them on import.

Exporting FBX from 3ds Max with Custom Properties

– Right click on the object
– Select Object Properties

– Type custom properties to “User Defined” tab (it seems to be single string text area, not line by line)
– For example to make it useful,  add some delimiter to your data: myvalue|anothervalue|somethingelse|…, then split the string in Unity.

– Export FBX normally for Unity

Using OnPostprocessGameObjectWithUserProperties() to read those custom properties

– Create new C# script : FBXCustomProperties.cs
– Now select your fbx file from unity project window, right click on it, ReImport
– In the console window you should see your custom properties printed out

using UnityEditor;
using UnityEngine;
using System.Collections;

public class FBXCustomProperties : AssetPostprocessor
{
void OnPostprocessGameObjectWithUserProperties (GameObject go, string[] names, System.Object[] values)
{
for (int i = 0; i < names.Length; i++)
{
string propertyName = names[i];
object propertyValue = values[i];
Debug.Log("Propname: " + propertyName + " value: " +propertyValue);
}
}
}
