"Light is Octane Light"

it work not with octane lights...use a poly with light emission...

Why do you say this? An Octane light is a poly with light emission, with the same features that you can see in any object with light emission ...

Thanks,

This is your scene corrected to see something. You need to add a procedural texture at least to the absorption input to render a procedural volume ... in any case, what are you trying to do? Because if you want to render atmospheric effects, the volume objects are not the way to get them.

Thank you, Juangon. It also seemed strange to me that this effect needs some kind of special illumination. Since in my opinion, the light of Octane is also based on primitives with illuminations of photons. That is, the difference between the source of illumination of the Octane and the polygon with the material of the emitter should not be - either at all or significant.
All the same in my opinion it would be much easier if the user could immediately see at least some result, simply connecting the Medium node. And then already could make any changes connecting additional nodes.

hi juanjo,

i say "Volumetric Lights" work not with octane lights...thats a another case as your show...you show a volumetric object with a volumetric medium node...thats another case...so show us please a octane light he send out a "volumetric light beam" for example...i test it with Oliver from Origami Digital and we find only the solution he use a "real poly" and not a octane light source...thats was in the end the reason that i open that thread here p.s. all example scenes use a real poly for "volumetric lights"and not a octane light...or?

This is an Octane light in a scene configured with the environment medium and it seems to work fine. Believe me, the Octane lights are only mesh objects with emission materials, I can't figure why they are going to have other behavior.

Thanks,
