Cable component fades while moving over the Skybox and disappears while over the Volumetric Clouds. If a Material is applied to the Cable it'll fade & disappear while the character is not moving.

Repro Rate: 4/4

Tested this in //UE4/Release-4.27 @ CL#18319896 and the issue did not occur there, it is a regression.
