Separate Reflections, Light and background.

In an outdoor scene I'd like to separate the reflection environment from the lighting and also from the background picture.
For example :
The scene is lit by a sun+sky
The background is a JPG file
The reflection come from an HDRI file
How to achieve that please ?

Hi Fabrice,
- enable multi pass beaty Environment and Reflection
- enable Alpha channel in the kernel settings
- set the sky + sun as primary environment
- set the HDRI as Visible environment with only reflection ticked
- compose the layers in your prefered image processing app.
voilà

Thanks again for your answer Beppe !
I'm sorry I'm an octane beginner...
How do you set the sky + sun as primary environment
and set the HDRI as Visible environment with only reflection ticked ?
I don't know where those options are...

Hi Fabrice,
sorry, which version of OctaneRender are you using exactly?
Standalone or integrated plugin?
