I need to understand why this is happening. I have tried to remove nodes from the material, the roughness, metal nodes, both from the chandelier and from the walls, I don’t know where the problem can be. If I put a single point of light on the scene, it doesn’t happen. If I add the chandelier (mesh with flame) then all the walls end with these small reflections that look like projected lights like a starry sky. Does anyone know what it could be? Thank you very much in advance! Have a nice day 
Hi!
I think your light intersects with your mesh (chandelier)! Try to move the light a bit further away from the mesh! Or if you placed it inside the flame then just move it out…
