Executing spawning on the server is exactly correct, but you’ll have to use _RepNotify_ for cosmetic changes as they aren’t replicated themselves. Unfortunately, I don’t have access to our project right now. Basically, what you have to do is instead of setting the material/color directly on the server, change a variable that’s flagged as _RepNotify_ (e.g. bSetColor or IsActivated or whatever). Then in reaction to the auto-created (client side) _OnRep\__ event , execute the color change. In general, I found this video series extremely helpful: > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline.
