In this video, you will learn about adding context to your Twinmotion models. Twinmotion uses OpenStreet to import all the data you want for a context model. Using the Context tool will bring in builds, roads, trees, and areas from OpenStreet. You have complete control over all this data as individual geometry after completing the imported context.
