How to Gizmo on empty node?

Questions
1

Hi I am trying to add gizmo on the parent of the mesh selected.

Although it is working fine if the node has mesh but when it is just empty parent node i am not able to apply gizmo on it.

here is a playground example I created please have a look -

https://playground.babylonjs.com/#CR09RC

here you can un-comment the line 23, 24 to see it is working fine in that case but not in the case of alloys.

below is the screen shot of the hierarchy of the GLTF,

I also saw - Gizmos wont work on TransformNodes and are Bones TransformNodes?

But was not able to get my head around. Please suggest the right way

This should work now as @Cedric added support for TransformNode

Please wait for him to get back from vacations :slight_smile:

Hi @nipundavid

Can you try with gizmoManager.attachableNodes instead of gizmoManager.attachableMeshes ?

There is an issue with parenting. I’ll take a closer look on that.
I’ve changed your PG with disabled parenting and it works but there is some offset. This offset might come from the .glb. Can you check if that the source scene has that offset?

The offset might be because that the mesh is not where the root is
you can download the glb file from this link for testing

Thanks for looking into it, looking forward for the reply

PR is here : Gizmo parenting by CedricGuillemet · Pull Request #8896 · BabylonJS/Babylon.js · GitHub
it will fix the parenting issue when translating the node. But in your glb, as the local 0,0,0 is not properly placed, the gizmo will be aside your mesh.

Hi @Cedric,

quick question - Is this feature available on react-babylon as well now? as I am using that in my project

I guess so. If gizmos are available then this one is as well
