Octane Layer to remove shadows

[dinopower]

Can someone tell me how to use Octane render layers to remove shadows in a scene. Is there a tutorial on this for Octane Blender? I know I need each object on a different layer, but I can't figure out how to do this myself.

There is "Shadow Visibility" checkbox in Object Data tab but its not working in 2.25. In v3 it is working fine.
In standalone application it is working too using "Object layer map" node.
