I’m working on a Fortnite-esque game for Unity. Player spawns in, has ability to spawn cubes to make a “base”. Everything works perfectly well in mono but I’m having a strange issue with networking. On the server, my player can spawn the cubes perfectly according to the Raycast hitpoint while on the client, even though the player is a clone of the Player prefab, the spawned objects always either end up at the world origin, rather than Raycast hitpoint -or- if I remove “if (!isPlayLocal) {return;}” from the player’s script containing Raycast info, the cube spawns inaccurately and without its corresponding material. I’ll try and pinpoint the code so I can place it here but I imagine it could be a number of things. Local Player Auth is checked off on spawn prefabs and all prefabs have been registered in Network Manager.
