Sorry, should have tested using object rotation, of course not going to work, as you correctly state it requires rotation of all around central point. Have amended by earlier post.
Lumion does not have a group feature so that all objects within that group are rotated as a whole, rotation even when multi-select is used is around each objects axis.
I don't think you should start from scratch though, as it should surely be least a little quicker dealing with the current scene objects than having to ensure you replicated all objects needed in the scene. It might require placing some items in layers to hide and show as you work through.
I still think though that to avoid that re-work simply offsetting the direction of the sun should work. Perhaps I'm still missing something critical so please correct if wrong.
For example, if the building was placed as facing north and it should be east, then for all sun directions, just add the difference to the direction. This seems to work OK in a test with animating the sun using the Sun Effect by adding 0.25 to the morning, midday and evening keyframes. The only thing this work-around doesn't account for is if the terrain had notable features from the first build of the scene, so the sun would be out of position. However, if that's not a problem, then using an offset seems to work and give shadows for time of day correctly.
Your comment is noted for sun study issues.
