Problem with lights in the plugin

Hi,

I have a problem in understanding how to light up my scene with the integrated plugin.
I created a new scen with nothing than a cube, a plane and a camera with Octane-Cam-Tag.
Then I call up the C4D-Plugin, choose Directlighting or PMC or Pathtracing and / or set Octane as the render engine in the C4D-render-dialog.
I disabled the 'Lichtautomatik' in the C4D options.
No other lights are added to the scene so far.
When I hit now the render-button (or preview inside the plugin), I see an ambient-lit scene.
OK, might be the default when no lights are added.
Now I add a light with an Octane-light-tag and hit Render (Preview) again.
Normally, the ambience should be gone now and I should see now my scene only lit by the light I added.
But I always see a washed out, ambient lit scene as before, no matter what I do with my light.
I see that my light has effekt on the scene, but I cannot get rid of that ugly standard-ambience.

What do I wrong ?

OK, I found something that might be the solution.

When I add a sky-Object with a black C4D-Standard-material, then the scene is only lit by my lights and the ambience is gone.

Is that the way to set up the basic lighting correctly ?

1) add a sky-Object with a black C4D-Standard-material to kill the standard ambient light
2) Set up my lights in the scene.

hi, simply add an octane environment object and lower the power interactively until you match the desired illumination ;)

Many thx, Beppe.

Octane need a light source to rendering. If you don't have a Sky object Plugin makes a default texture environment.
If you put one or more Sky Objects, Plugin uses first one. If you put a directlight/sunlight then Sky objects will be ignored. Daylight Environment is activated.

Adding a arealight not disable the Sky object. You must put a Environment Tag with texture or color nodes or a standart material.
That'a all.
