I had to investigate the sun hours received by the house in a certain location. I run the calculations in ladybug which revealed that the surrounding buildings do not affect the sun hours in the examined period.
I wanted to create the visualization showing the shadow at chosen hours of the day.
And here is my problem: Rhino sun shows that the buildings DO affect the house by taking 12 minutes from sun hours.
The same visualization made in the unreal engine shows that shadow does not “touch” the building.
However, the difference in the shadow’s positions is huge.
Why the difference is so big and whom I should trust?
