two sided indirect lighting issue

Hi,

I have 2 objects from the unreal demo and they are not correctly lit. The material editor is doublechecked and the light is not to dark. Both objects are static Skylight has a Hdri in it and is set to static. Directional light is stationary.

Any ideas why this could happen ?

These objects aren’t UV mapped and can’t be baked in. You need to make them moveable if you want to build the lighting in the level, or you can UV map them in Maya or Max.

Thank you for your answer buts that is not the case. They are official from epic and everything is correctly uv mapped. The objects work in direct sunlight but not in this indirect situation. …
