Bug. Invisible light of custom item.

[Maris]

There is light on client side (on dedicated server). But other players do not see the light. Only owner of the item can see the light.

[Sarcen]

I guess equipped items only exist on their owner and server. That`s why the normal the torch spawns a separate prefab for the light effect.

[DarkXero]

Light doesn't travel through the net. When you equip a torch, as @Sarcen said, host and client spawn a torchfire prefab.

 

If you look at the torchfire.lua prefab, you will see that all the light operations to set it and enable it are before the "if not TheWorld.ismastersim then". Client sends rpc to equip item, its a torch, host spawns torchfire prefab, host and all clients get a prefab with light, torch runs out or is unequipped, entity gets killed in the host, so it's killed across the board and light dies.
