hi this scene is imported from a model in Cinema 4D. It is very large because there are many office buildings. in Twinmotion 2024\.1 preview this happens by activating lumin. what am I doing wrong?...

Interestingly enough, I have the same issue. I import c4D file from Vectorworks 2024. Do everything as I did before. But have the same result as yours… Would be great to hear something from Twinmotion on this as this makes 2024.1 useless as long as you wish to use c4D files…
