Cloning Clones (Render Instances) not possible?

[Mindspi3D]

i have a Scene, where ich clone some spheres on the Surface of an object.
now, i put this into another cloner and want to clone this again.
i set all as render instances to save Performance.
the problem is as follows:
when i untick "render instances" in the first cloner, it works as expected, but the editor performance is weak AND the gpu memory consumption is rising.
when i activate "render instances" in the first cloner, octane does not render those clones (the spheres on the original object).
it only renders the cloned object correctly, but without all the spheres "sticking" on that object.
do i miss something?

You can't use embedded render instances in render instances. Just use one level of it.
