So i am importing lights from 3dsmax2023 to UE5.1 with Datasmith. After the import, changing the setting do completely nothing, even if i turn off intesity to 0 it still emits light. If i move the light and then Ctrl+Z, it said “Undo: Move elements”, but the light still moved. What is happening?

I’m having this problem as well. Unfortunately could not find a way to fix it. Have you had any luck so far?

Those lights are Datasmith Area Lights correct?
We have a related ticket that we are trying to fix for 5.3

I’m having this same problem from Revit with the Live Link. The lights are coming in at very low intensity and I cannot change it

I also encountered this issue. After trying to modify the lighting parameters, I opened the lighting blueprint and compiled it. At this point, the lighting settings for the scene will take effect. But I hope that adjusting the lights during runtime,This method cannot solve my problem.

Ok tested and it’s working on 5.3 Preview 1. Thanks!
