Hi Buzzooo2,
Ray Traced Distance Field shadows do not get baked. These are a fully dynamic solution for shadowing.
These can be used in conjunction with other light mobilities. For instance, static lights will only light objects that are static in the scene, however, if you have a light with its mobility set to stationary the Static mobility actors in the scene can receive baked static lighting and any dynamic movable object will receive RTDF shadowing.
I hope that helps.
