Reported in SF [Link Removed] and [Link Removed]
Users on Mac are reporting inconsistent rendering results for Lumen in image exports that do not include any settings changes.
When exporting some media that had Lumen enabled, rendering results can vary greatly, with different lighting exposure, reflections, and other artifacts.
Users indicate this problem was present in Twinmotion 2025.1.0 and appears to have become worse in 2025.1.1.
One user mentioned that this occurred after reloading a saved scene, and the workaround was to reapply any glass materials with a new version of the material from the library to achieve consistent results, but this no longer works in 2025.1.1.
One user was able to share one of their scenes where they noticed the problems. I have not been able to reproduce the problem in DX11 on Windows so far in the same scene or a new scene.
