When creating VRaySettingsEnvironment in Unreal make sure its location is set to 0,0,0; rotation is set to 0,0,0 and scale is set to 1,1,1. You can create multiple VRaySettingsEnvironment actors in the level but you have to specify in the Environment slot of V-Ray Settings tab which one should be used at render time.
