When I first installed Twinmotion at the beginning of 2023, I was able to add a light source from the library, which is set at 300 lumens by default. However the past 9 months, I would have to adjust the lighting to be at least 200,000 lumens. Other computers in our office also have to do the same adjustment in order to see the light in our views. I am using Twinmotion version 2023.2.2 and this also occurred on previous versions. I also use direct link from Revit to load in models.
