Hi everyone,
I’m using Twinmotion 2026.1 HF2 with Lumen and experiencing a lighting difference
between the Twinmotion viewport and my exported Cloud Panorama Set.
Some rooms look correct inside Twinmotion but become much too bright in the Cloud export. Other panoramas in the same set look fine, despite using the same settings as far as I can tell.
Previously, I noticed that Lights bias under the shadow settings was at approximately 70%. Reducing it to 0 fixed the appearance inside Twinmotion. However, after exporting and uploading the Panorama Set again, the affected rooms still appear overexposed, almost as if the previous settings were still being used.
In the attached screenshot, several thumbnails on the right are almost completely white, while others look normally exposed.
My questions are:
-
Is there a known Lumen panorama export issue affecting 2026.1 HF2?
-
Is there an additional update step needed to ensure that the Panorama Set uses the modified shadow settings?
-
Which settings should I check to identify why the viewport and exported panoramas differ?
I would prefer to keep using Lumen because of the rendering time required for the full set.
Any advice would be appreciated. Thank you!
