Hi there. I believe this is editor related so you can ask future questions in the other forum. Anyway since I did that just few days ago, looking through the cinematic models. I'll be happy to tell you:
In the editor click 'File' click 'Dependencies', click 'add standard' tick campaign and it will load all the models and units from the campaign. There go to the Unit layer, choose 'Storymode' units and there you will see you can place all the models from the cinematics/inside hyperion including Tychus standing. You can see the previewer where the model is located once you use it in the editor.
