I have achieved an explosion that affects nearby static meshes, but I cannot replicate it.
I’m not super experienced with replication myself, but from what I understand I can think of 2 ways you might want to do it, depending on the context and needs.
You can either perform the explosion locally on each client, triggered by the server, or you can perform the explosion on the server and replicate the transforms (and anything else) of the objects affected. If the objects/meshes have collision and will impact gameplay, do the latter. If they don’t and are purely aesthetic, the first method will be more efficient.
The reason to do the 2nd method if it affects gameplay is that it would be very important that each object has the same transform on each client, which means the server should have absolute authority over where the objects are.
