Most of these errors occur because the required models have not been preloaded by the Editor (or downloaded by your computer, although this is unlikely). Check your dependencies - adding Void (Story) and Void (Campaign) should cover all your bases since they include data for Liberty and Swarm.
Check the model data in the Cutscene Editor and see if you can bridge any gaps. A quick search of models with the Void campaign dependencies has yielded no HyperionAirlock.m3 for me, so I don't know how you found that. Regardless, sometimes unused data becomes deprecated and is no longer functional, sometimes given by Zz or zz deprecated. Occasionally, a sprinkling of units and doodads give checkered domes instead of models because they have none attached or reference a model which does not exist.
