Day 2. For a sample pic, I think 2 walls are enough... Mmmhh... The scene is too simple... I have to add something... Tomorrow. Tips: - To create a scene, in a special case if large, maybe the following ones are the best steps: 1) create the plant of your room posing floor Modules on ground (suggestion: if the room has a standard height, use the 'Floor+Ceiling figure) 2) create each wall separately on new scenes. Its more easy place modules starting from the 0 postion. 3) once you have created a wall, choose one figure and using the Hierarchy Editor parent all the other figures to it, simply dragging and dropping on the only one part of the that figure. 4) save 'The Whole Group' in your library. 5) now you can import the whole wall on your main scene and selecting the father figure, you can move it to the right position. - Creating more then 1 main scene with just the needed walls help to save resources. (Ex a scene with floor, ceiling and walls 1+2, another scene with floor, ceiling and walls 2+3, ... etc.)
