In OR3:
You can select the mesh and apply the material?
You can select the mesh coplanar? "obj with single material"
Here I exploded srf and created two different materials to be imported in octane.
Thanks!
You can select the geometry coplanar OR3?

Rewrite the question. 
Version OR3 ......
The question is:
You can select the mesh in Octane Render 3 Standalone Lic, new version, ..... select a portion of planar mesh and create a node material.
Have command selects coplanar mesh is difficult to implement?
Function selects mesh coplanar well as select material.
As I wrote before, I do not use the plugin, I do a lot of work before importing into Octane. You lose too much time ...
I wish I could create groups of material, this group refers to the selected mesh.
I want to be free from 3D modeling program, I have to do the render with octane want to assign the materials in octane. In octane I decide which materials to create, but if I have groups of mesh already made above (OBJ file) I have to do it all.............................................................................................................................................................................................................................. If I forget to assign the material to a railing I have to re-import all.
Great saw ....... booo.

Hi,
Octane is still and only a render engine, it is faster and lighter also because it doesn't has all the unnecessary stuff that you can find in any modelling app. Having said that, if the material is already available, you just need to assign the material to the new face in your host app and reload the mesh with the proper button in the node inspector:
nothing else 
If the material is not already present, you probably will lose some connections with materials. In the past, when there was the standalone only, my strategy was to export extra materials assigned to hidden cubes (in general under the ground or in places not visible from the camera). In this way you have more flexibility if you have to change the scene later on

But ..... so.
Guys! I know what's octane .....
I HAVE NOT SAID TO MODIFY GEOMETRY IN OCTANE!!
If I have a complex scene is very likely that you need to re-import all. This is because a mesh is part of a wrong node. OK?
Add a selection command mesh giving the possibility to create a node on the selection. This command allows you to not lose hours of work to create the materials.
Apparently, those who have the standalone version of octane import keychain. Or everyone likes to export tens of times obj file. Or all have clear ideas before going in octane. Lucky you!
Did you know that the materials are created twice in this way?
.... To you does not seem fuxxed up? .. I think so!! and also pretty big.
Thanks!

I do dozens of unnecessary things and hope not to have committed mistake? .... Is this a correct workflow, do you think?In the past, when there was the standalone only, my strategy was to export extra materials assigned to hidden cubes (in general under the ground or in places not visible from the camera).

Sorry, I have surely misunderstood your question but it's a bit hard for me to get the point of this discussion 
I think that if you want the freedom of modelling while rendering in Octane, then you need a modelling application with an Octane integrated plugin. In this way you can change the mesh and the associated materials on the fly in real time while rendering. But you cannot expect this from the standalone... just my two cents.
Anyway, reloading an obj is a matter of seconds and if you have big complex scenes, why don't you simply split the export in parts and combine them with a group mesh node? In this way, should be more easy and fast to update only the modified geometry

It is what I do.It is still more work.
This is not beneficial workflow.
Current workflow with a command, mesh selection can not be compared.
I again the example of other Standalone software, as Maxwell Studio.
I understand that octane should be light and essential, etc. but we speak of selection commands. It does not go against the philosophy of the software.
Stop workflow, go back and lower the performance of your PC to run two applications at the same time is a contradiction.
