Why does the mouse keep active and block my rotation view when I disable it ?

Here’s the blueprint: . posted by anonymous | blueprintUE | PasteBin For Unreal Engine

But it does if I am pressing LMB and RMB, strange.

In the Event Begin Play of your blueprint, try calling the “Set Input Mode Game Only” node and connect your player controller to it.

It’s worked thanks, but I needed to call Set Input Mode Game and UI instead.
