Twinmotion - Introduction to HDRI Environments 

You're very welcome, thank you for the feedback!

You're welcome! It is great to see that there is some local content for these images for sure.

Thanks very much, glad you are finding the videos helpful! I use infraworks because of how quick and easy it is to produce the context and surroundings. I'm often not too concerned with the accuracy of the contour's or landscape, because that isn't the focal point of the images or videos we produce. Perhaps something like Civil 3D might be the best to insert contours? The best context would probably come from an HDR or physical photo that you have taken yourself. As for the coordinate system, Twinmotion just has a "Local" and "World" coordinate system. How they link to softwares like Revit or infra I'm not quite sure. I usually export all my models from the various softwares, then position them correctly in Twinmotion. After that I make sure to set my location on the map for accurate solar representations, and set my north direction to further increase accuracy of shadows. Hope this helps!
