In the Settings tab of the OctaneRender Setup Window is a Configuration button. The OctaneRender for ArchiCAD plugin does all the conversion of the ArchiCAD scene to Octane for you. However, there are some settings which you can tune to speed up your workflow. Mouseover each of the settings for more details.

In summary:

SpecularAmount of specular reflection, or the mirror-like reflection of light photons at the same angle. Used for transparent materials such as glass and water. Percent – The minimum Transparency Transmittance which will result in an ArchiCAD material being converted to an Octane specular material.

Emission Percent – The minimum Emission Attenuation which will result in an ArchiCAD material being converted to an Octane diffuse emitter.

Warning on Missing TexturesTextures are used to add details to a surface. Textures can be procedural or imported raster files. – If during the scene conversion to Octane the plugin cannot locate a particular texturemap on your file system, a warning will be displayed if this checkbox is ticked. It is recommended to leave this option on.

Viewport Refresh Rate – The number of milliseconds that the Viewport will check to see if Octane has an updated render image available.

Progressive Save Enabled – Tick to have the plugin save the render every “Save Interval” samples. Useful for analysis to determine have many samples are required for a render to be finished.

Image Save Format – the format that the Viewport image will be saved as when you click the Save button on the Rendering tab.

LiveDB Texture Scaling – The scaling of LiveDB textures will sometimes not be appropriate for the scaling of your scene. Adjust this setting to increase or decrease the scale of LiveDB textures when they are downloaded.

Scene Scaling – Enter values < 1 to scale the entire scene down. This should not be needed, but might be useful for SSS and rayepison tuning. If values < 1 are used, reduce the default rendertarget rayepsilon.

Maximum Scene Triangles – The maximum number of triangles/polygons that will be loaded into Octane. Increasing this value will mean more RAM is required to load the scene into Octane. The maximum triangles that can be loaded into Octane is approx 30 million. This setting excludes polygons from proxy objects.

Scene Refresh on View Change – When checked, this causes a scene refresh of the Viewport when you select a new 3D View.
