Ugly Lighting for my plants (even with no overlapping UV)


i ve a silly problem with my little plants in my archiviz scene…they have usually the backside totally black and awful.

Normally the same exactly model with the same exactly texture renders good in a blank level it happens this only on my archiviz scene. The model has UV for lighting, the light resolution on it is at least 256, light building is set to production…how can i fix this ?

ok so one way or another i managed it by unchecking the double side material of the plants. Now some leaves from certain point of view are hided, but at least they doesn’t seem so wrong.
