So I try to have one scene with cycles for my planet where I have a shader that helps me with the atmosphere generation. And I have a scene with my space ships that I want to render with octane. In general I can select the different engines without problem and can make a composition. When I start to render though no matter which render layer I use to composit my images in one of the scenes ends up with wrong colors/brightness. So either the planet is wrong or the ships. Looks like I am forced to render them in different files or only single and then put the images together in Gimp. But this is my least favourite solution. Hope you can help me with that.
