For now, you'll have to manually transfer all attributes that you want to use in Shading to the Point Attribute level.

Easy, but what's next?
I can set color attribute to primitive or point whatever, but how should I use it as a color in the Octane Material?

According to the release notes, there are two new VOP nodes for Shading: Color Vertex Attribute and Float Vertex Attribute

Is this about Octane 2019, or Octane 4?
Because I see no such nodes in Octane 4:

This feature is available in the Octane 2018.1 plugins only:

That is really sad since it's a core feature of Houdini.

Did you find a solution alex?

I guess for geometry — baking colors to texture (or texture sequence) with Mantra and (after that) using it with Octane is the only option in v. 4.
Since I still haven't decided should I subscribe to 2018+ or look for alternatives, I don't see any other options.

I also found this video as a solution: https://vimeo.com/172594655 by Rohan Dalvi

Fixed in 2018.3
