Mixamo has just released a video tutorial here. The video describes a workflow for doing visualization in Unity with characters. There is an emphasis on using Beast for light mapping and light probes for dynamic objects. We are attempting to use as many free resources as possible in this pipeline and hopefully it can give developers a good sense of how to use our tools. The video is geared towards architects trying to add people to a real-time environmental visualization, however these techniques work for games as well.
If anyone has ideas about other resource that could aid this type of workflow, we would love to hear them.
