I am looking for a method to pass custom metadata about an object from the Blender file to the Verge3D scene. A method like this could be used to embed data such as the price, weight or other physical attributes of a real-world object in its 3D representation. I did not see an easy way to do this.

The V3D Object3D base class does contain an object called .userData that can store custom JSON data about the 3D object. I can populate this data programmatically, but I cannot set it from Blender.

Is there any way to achieve what I am looking for in the current build of Verge3D (1.05)? Any ideas would be appreciated.

Thank you,
Jem

Hi Jem,

User-defined data can be exported and accessed as follows:

1. Create and set a property in Blender
2. Select Export Extras in the export options (on the left toolbox) upon exporting to glTF
3. Then your property should appear in .userData
var obj = v3dApp.scene.getObjectByName(“Cube”);
obj.userData.myprop // e.g. 123

We should definitely describe this in the manual.
