You can change the attributes of a room with the Room Editor. Whenever a room of your model is selected, its data will appear in that window.
When multiple rooms are selected, changes will apply to all of them.
This is the room currently assigned to your selection.
If the room comes from the RoomBox library, variants might be available. Use the "Lighting" list to pick those variants.
Clicking the room's thumbnail will open up the library so that you can browse all the available rooms.
Rooms are available in both low and high resolution.
The Viewport / Enscape option lets you pick a resolution for the room shown in SketchUp viewport, as well as in Enscape renders since it directly uses the materials stored in the model.
The V-Ray / Thea option lets you pick a different resolution for renders with those engines.
Because using a high-resolution map will produce heavy SketchUp files, we recommend to use a low-resolution map in the viewport and a high-resolution map for rendering.
This is where you can edit the size of the room as well as its offset from the window.
The Width, Height and Depth attributes control the dimensions of the room's walls.
The Window offset attribute controls the distance between the window on which the room was placed and the actual geometry. This is useful to add a bit of depth depending on the thickness of the window or the recess of the facade.
Each sprite can be toggled on or off using a checkbox. Sprites can also be moved along the room.
Each wall can be individually toggled on or off. This is particularly useful to create special configurations, like rooms at a building's corner or patios without ceilings.
