During the beta test of ArchiCAD 18 we tried to find a solution for this, but it is related to the C4D engine. We reported this to Maxon, so I hope in the long run they will be able to optimize the engine. Until then the best is using the Physical mode.
With Physical Renderer turned on.
What we have discovered is that if you give any of the plants a transparency then the Cinerender does not know how to handle, you have to keep them all at 100% but then in OpenGL with Shadows they cast large blocks of shadows not one that matches the plant.
