Error when trying light.excludedMeshes.push(button3d)

Bugs

Hello everyone, I am trying to create a Button3D that works as a billboard in a way that is not affected by Lights.

When I try to add it to the excluded meshes, the playgrounds throw the error:

s[a]._resyncLightSource is not a function

Playground: https://playground.babylonjs.com/#2YZFA0#390

Is it the right way to do it?

Button is not a mesh, so it doesn’t have the required functionality to work. You can do this:

Billboard Button3D Bug | Babylon.js Playground (babylonjs.com)

and remove button.mesh, which is the underlying mesh of the 3d button

I suppose another solution would be to change it to a holo button, then you can work it through the material by setting the ‘backMaterial’ to ‘disableLighting’. Something like this:

Thank you for the answers @RaananW and @mawa! I end up creating a custom 3d button.
