Virtual production cg element dark areas issue

Hi every body.
Excuse me if this theme exist somewhere else, but i don’t found any relevant response.
I’am creating virtual production project whit abstract scenes same as to image below. I have scene wich is compound of two 3D mesh.
A plane with reflective material in it and the sphere. Everything else is just light and atmosphere. In preview and simulation mode sems to be everything correctly.
However, when I use the cg_element the scene contains dark areas.
I wuld be glad if someone hellp me.
Thank you .
