To display the OctaneRender™ Viewport, go to the “Rendering”
tab and click the “Open Viewport” button. This will open a new window and start rendering the current scene in that window.
When opening the Viewport, any ArchiCAD scene materials are
converted to Octane materials, and the default scene lighting is
set to the Octane “daylight” node.
Whilst rendering the scene in the Viewport, you can move the ArchiCAD camera around, and this will be immediately reflected in the Viewport.
NOTE: When rendering large scenes, you can continue to work in ArchiCAD, however it is recommended that you switch to the “Internal Engine” in the “3D Window Settings”.
