can i slow down the speed and dont have to spin effects when i turn around the camera

looks this video - YouTube, can i slow down the speed and dont have to spin effects when i turn around the camera ?

I think you mean motion blur? You can disable it(set intensity to 0) in post process settings.

thanks for reply and how about the speed of walk ?

Yeah, motion blur is in post process volume settings. You can change the walk speed in defaults tab of your character BP > Max Walk Speed.

where is the defaults tab of your character BP ?

When you open up the MyCharacter BP you’ll find the three tabs at the top (From Left to Right): Defaults, Components, Graph.

You can find the default settings here to adjust or you can go under the Components tab and select Character Movement in the left panel to set a new default there at the source.
