Thanks for sending through that scene. You need to ENABLE smoothing for the material used on the column. Pls see FAQ question 1 at http://render.otoy.com/manuals/Revit/?page_id=416.I'm getting some artifacts from Revit, take a look at these rendered extrusions:

I'd need to see a a sample rvt file where enabling smoothing still results in a faceted render to provide a answer. The only explanation I can think of at the moment is that the individual polygons are not welded together on the object. In this case, the Revit renderer would also render faceted. Also - the geometry extraction process in Revit 2014 & 2015 is vastly superior to that of Revit 2013 - so upgrading to 2014 or 2015 will most likely rectify these sorts of issues.I'm aware of the smooth setting, but sometimes the Revit corrupts the geometry, and even the smooth material gets faceted. I was just wondering why the curve object get smooth on the viewport, and faceted on the rendering.

For example, if you have a default ORBX material containing a texturemap, if you copy the rvt file to another PC - you will need to also copy the default ORBX files (since the texturemaps used in the .rvt reference texturemaps inside the ORBX files). I think this is going to be confusing to users - particularly where you have saved a "Default" which contains a texturemap from the Revit materials library - which would exist on other PC's with Revit installed. Plus, once you have saved a default for a material, there is no way to edit and resave that ORBX (for technical reasons that I won't bore you with). The above issues exist with the LocalDb too on Octane Standalone (ie. once you have saved a material to the LocalDb, you cannot update it and re-save to the same LocalDb name).Have been testing out the save to defaults orbx feature quite a lot and it seems to be working great. The only bug I have found so far is when making a change to an already saved to default orbx material, and re-saving to default. A error occurs and the original orbx file seems to loose its embedded textures, as the file size reduces to about 15KB.
Other than that so far it is working great
So I think the best solution is to change the "default" material save format from ORBX to OCS. With OCS files the texturemaps are on your filesystem, so you can manage where they are stored and ensure they are copied onto other PC's when the .rvt is copied. Plus the OCS format is "future-proof" for any changes make to the Octane node structure and when loaded Octane will automatically convert the nodes form the Octane version they were saved in to the current Octane version of the plugin.
Happy to explain/discuss if people have questions...
The ORBX format is intended as an export container, and not designed for read/write (ie. update) on an ongoing basis. So it's probably the wrong tool for defaults. And yes, if you try to save over an ORBX in Octane Standalone, you will loose the texturemaps, which Otoy are aware of. So I think currently the best default format is OCS, but in the future maybe ORBX will be possible.I hadn't got to opportunity to chime in on this, but it is unfortunate that saving over an obrx file wont work, I had noticed this in the standalone previously. Is this an issue that the otoy team is working on? I feel like ultimately orbx is the answer to simplifying and maintaining a clean database of materials. I do understand your point in regards to revit users when using the material library of revit (however I am sure after gaining some experience with octane, most of these people will crave higher quality textures from else where). Ultimately if otoy fixes the overwrite issue of orbx, maybe the ability for the octane revit plugin to use both orbx and ocs formats would be flexible for all occasions. I do see occasions where having all my file consolidated in orbx maybe be cumbersome, when for example wanting to extract the texture on the fly for one off editing(meaning unpacking). But maybe this can even be overcome in the future, with an right click option within the plugin to unpack the default orbx material being used, and automatic relink the texture files to the unpacked versions stored within the live database folder.

- Set Subdivision level to 1 and subdivision sharpness to 11 and click the reload button for the mesh
- Set the height of the displacement to 0.1
The above only works for Octane Standalone (since the Revit plugin does not provide Subd controls).
If exporting a large scene - export to OCS, not ORBX. ORBX packages up the ABC animation file, whereas OCS leaves it as a separate file, which is less disk intensive.Do you have any estimate of when this will be available inside the plugin? There are several issues that make impossible to render large scenes:

The solution could involve the specification of subdivision controls into the material displacement parameters, inside the plugin.
Yes - all (non-proxy) geometry is contained in a single Mesh node. So if you are trying to subd a mesh element from Revit - you will need to subd the mesh node which contains the entire scene. Proxies on the other hand are separate mesh nodes.on large scenes, it's impossible to find and select the specific geometry that needs to be reconfigured/reloaded;
