> LiveDB do not have any architectural reflective glass;
What about the LiveDb material "glass architectural"? It probably needs "fake shadows" enabled.
> How to use a material made in standalone into the Revit plugin?
Current, you need to save it to the LiveDb. However in the future hopefully you will be able to access LocalDb materials from both Standalone and the plugins (but this is not currently possible). The idea behind the Revit plugin is that you don't need to use Standalone materials - simply create your materials in the plugin.
> Render statistics never display textures used (viewport window);
For me this is being correctly displayed. The number of texturemaps is in the "Textures Used/Total" line of the Viewport. If this is not working for you, could you pls post a screenshot of the Viewport statistics?
> The Octane plugin scene is not attached to the Revit 3D View - there is a lot of rework to be done after each render - every camera and environment settings need to be redone;
There are a lot of issues with the Revit API relating to camera matching. So to get an exact camera match, you need to leave the left and right Revit Preview window borders as they are. Once they are moved, the plugin cannot determine the correct camera angle and fov. This is covered in the manual at http://render.otoy.com/manuals/Revit/?page_id=67
. For environment sun direction, pls refer to the manual at http://render.otoy.com/manuals/Revit/?page_id=74
Hope that helps.
