Freddy,
I haven't been a Lightwave user since about 1995, so any screenshots from me out of C4D or Maya might just be more confusing. However, Lightwave Guru pointed out that the same tag I mentioned is available in Lightwave. "> LW Node Editor for Octane > Octane Render Target > Environment DayLight > "

What matters is that you need the volumetric tools added to your scene. The Daylight tag is one way of including them directly in a light source, but that's not the only way. Using a Volume primitive will do the same thing in a slightly different workflow, and it can be used with any Octane light source.

I thought your original question was very specific to quickly knocking out some god rays from the sun over a city, but I'm guessing you should spend a little time digging into the more general idea and workflow of volumetric lighting in LW. Here's are a few threads that should at least set you on the path.

Thank you so much for your clear answer!

I figured out how it works now, have seen some nice beams, with a medium object or just a medium in the render target, but the problem I have now is that when
I see some godrays, the sun is much too bright, it's or the godrays or the over exposed bright sun, at least in my tries.....
