solved Click / Pickup event triggered on mesh behind the sprite

[mind0n]

Refer to the playground url below, sprite is in front of the sphere, however the click / pick event triggered on backend sphere first regardless of the sprite's position.

Expected result:

Player clicked will be triggered instead of Sphere clicked.

Yep this is by "design". To save resources we are not doing both picking (mesh and sprites). We do meshes first and if no interaction is done then sprites. That is something we could revisit though

Thanks @Deltakosh for the response, is there any way to force the mesh (eg. plain) to always facing the camera?

I choose sprite to render clickable image because it always faces the camera automatically.  If mesh events will be triggered before sprite events, then I need a way to let the mesh always faces the camera so I can render the image on the mesh instead.

You can use meshes with billboard mode: https://www.babylonjs-playground.com/#UJEIL#13

or this old good SPS with planar quad particles in billboard mode http://doc.babylonjs.com/how_to/solid_particle_system  (they are pickable) ?
