There is a block in 3d. When it is destroyed, it is necessary that 3D particles appear, such as pieces of the earth crumbled.
The particles are in 3D, yes.
You did not understand. So that one particle is a 3D model, and not a sprite or tile.
Unfortunately, our particle system currently only uses sprites.
There is no 3d model particles yet as I understanding. You may imitation this particles with sprites particle by orient spawning GO normal (rotation) to the camera. For big parts of destroyed block you may spawn pack of GOes with small block model and dynamic physic colliders (and apply some random force for each one). Then after delay destroy them.
Yes, thanks, I thought about it. I just thought suddenly there is a ready-made solution from the engine.
