Add data in mesh

[Andrey Zimin]

Hi friends. Let's say I created a sphere and want to her to bind some parameters. I remember that mesh there is a special data. Tell me exactly how to do it! I think there is some official method to add your data

Hi Andrey!  I think most use node.metadata.   It is on node, so it is on mesh, camera, and lights.  I think it is included in serializations and parsings, so it can be added in modelers, too... and will export fine.  I have heard that some people put a json object in that property, which can carry a ton of data.

sphere.userData = {};

sphere.userData.whatever = sphere.userData['whatever'] = 'yup...';

use the ['variable-name'] for safety and so you can be more specific on naming.

Hey @Pryme8... when 'userData' is added (to a mesh, cam, or light) in Blender... via Blender Custom Properties, does it export/import correctly?

Will sphere.userData exist on mesh/cam/light... after import in BJS scene?  Anyone know?

(the above is old post, so I'm not sure if still pertinent)

I see 'userData' mentioned there, twice.  *shrug*

I think I am behind on my reading/learning.    Info welcome.

Hi All,

Babylon js using ***.metadata not ***.userData

[Pryme8]

if you are using the serialize it should not matter...
it should turn it into a string regardless and propagate it back when you de-serialize it.

That I don't know,  I don't use Blender and never will. (c4d for the win)
