Please updaterotation. Rotate Around Vector. December 02, 2017. UE4 Version: 4.18.3. In this tutorial we'll learn how to rotate an actor around a vector point. For this example we are going to use a fixed vector point, so every frame we want to set our fixed location by setting our NewLocation to a fixed FVector.
To make our water look cool and eye-catchy, we’ll give it a little glow of its own. We can add a ‘Constant 3 Vector‘ to Emissive Color and give it a Cyan hue. For the Opacity, we need to add a ‘Fresnel‘ node and connect a ‘Constant‘ to its ExponentIn parameter to control the strength of the effect.
