This is the look I'm trying to create:
(Discoball, spotlight & reflections on the wall)

This is my current test scene:

My Render Settings:

Metalic material for the ball:

My questions are:
- How to create a sharp spotlight with octane. (currently it's only a plane with a blackbody emission which gives light to the whole scene, but I wont it only on the discoball)
- How to make the reflections/caustic much more visible in the scene?
- In general, what settings should be changed? What should I do different?
The scene can be downloaded here:

Thanks for your help!
