ADVANCED MODE

Settings -> Always Advanced Mode on: This displays additional options, sliders, buttons and parameters which can be adjusted in Lumion. If you do not want to see the advanced options all the time, you can turn them on temporarily by pressing the CTRL key to see extra options in the following modes:



  • Import / Object modes: 5 Layers are available in the top left corner, and "Move Object" displays additional Rotate, Pitch and Bank buttons as well as a Uniform Scale button.
  • Movie mode -> Save Movie: MP4 or Image sequence, 2D or 3D (stereoscopic) rendering, Extra frame edge (This increases the render time but can eliminate Godray/ambient occlusion shadow artifacts along the edges of renderings).


SELECTING, COPYING, MOVING AND ALIGNING OBJECTS

***** Import / Objects mode *****

(CTRL) + Drag with Left mouse button: Rectangular selection tool for selecting multiple objects.
(CTRL) + (SHIFT) + Drag with Left mouse button: Add new rectangular selection to existing selection.
(ALT) + Move selected object(s): Copy-paste selected object(s) by pressing ALT while dragging one of the selected objects.
Place object mode -> (CTRL) + Left-click: Randomly place 10 copies of the currently active object library model.
Place object mode -> (Z) + Left-click: Place a new object with +/-0 to 50% random scale.
(Escape): This "advanced" move mode lets you move objects by clicking directly on objects and dragging the mouse to move them. In addition, (H) lets you move objects up and down while (R) allows you to rotate them.
(G): While adding or moving objects in your scene this key allows you to turn off 'snap-to-vehicles and -people', so that you do not accidentally stack new objects on top of these object types.
(F): The orientation of all objects (apart from Trees/plants) can be made to adapt to the inclination of the Lumion terrain. Move object button -> Hold down (F) for "Flatten" -> Move the object(s) to make them adapt to the inclination of the terrain.
(CTRL) + (F): The orientation of all objects (apart from Trees/plants) can be made to adapt to the surface angles of other objects. Move object button -> Press (CTRL) + (F) for "Flatten" -> Move the object(s) to make them adapt to the surface angles of other objects.
(SHIFT) + Move selected object(s): Press shift while dragging selected objects to move them horizontally with snapping turned off.
(CTRL) + "Same height" command: The selected objects will be placed at the same height as the object you clicked on. (CTRL)-select objects -> Modify objects -> (Click on the Menu icon of the object that has the height you want the other objects to inherit -> Transformation -> Same height.
(CTRL) + "Space" command: The selected objects will be placed in a straight line as defined by the objects that are furthest away from each other. (CTRL)-select objects -> Modify objects -> Click on the selection icon of one of the selected objects -> Transformation -> Space)


SAVE & LOAD CAMERA VIEWPOINTS

***** Weather / Landscape/ Import / Objects modes *****



(CTRL) + (1) (2) … (9) (0): Use this function to save up to 10 camera positions.
(1) (2) … (9) (0): Load previously saved camera viewpoints. The saved slots are also available as easily accessible thumbnails in Photo mode.


IMPORTING & UPDATING MODELS

***** Import mode *****



Edit Materials -> (CTRL) + Reload Model button: If you import a model that uses over 100mb of texture memory, Lumion will cap the maximum texture resolution at 2048x2048 pixels. However, you can bypass this limit by pressing CTRL while you click on the Reload model button. If you apply a Standard or Lightmap material to your imported model, any texture you load will be loaded at whatever resolution your graphics card is capable of displaying (up to a maximum of 16384x16384 pixels).
Edit Materials -> (ALT) + Reload Model button: If the name or location of an exported object file (DAE, FBX etc) has changed, this option lets you select the location/name of the file manually.
Animation on/off button: This function lets you import move/rotate/scale animations via FBX/DAE, for example from 3D Studio Max (FBX is the recommended format for animated models).
Imported material scale: If you apply a Standard material to an object, a Scale slider value of 0 means that the imported texture coordinates are used.


NAVIGATION

***** Weather / Landscape/ Import / Objects / Movie mode *****

(W) / (Up arrow): Move camera forward
(S) / (Down arrow): Move camera backward
(A) / (Left arrow): Move camera left
(D) / (Right arrow): Move camera right
(Q): Move camera up
(E): Move camera down
(Shift) + (W/S/A/D/Q/E): Camera moves twice as fast
Right mouse button + Move mouse: Look around
Middle mouse button + Move mouse: Pan
 

MISCELLANEOUS

***** All modes *****

(F1): Editor quality: 1 Star
(F2): Editor quality: 2 Star
(F3): Editor quality: 3 Star
(F4): Editor quality: 4 Star
(F5): Quick save (Saves a file called QuickSave)
(F9): If you press F9, all trees and plants in the viewport will be rendered at their best level of  detail, so that it's easier to see where you need to add more trees and plants in a scene.
(CTRL) + (F11): Fullscreen
(F11): Maximize window with/without taskbar (Press twice to toggle)
CTRL + U: Update the 360 degree reflection texture.

Sliders: You can double-click on all sliders in Lumion to manually type in values. Press Shift while adjusting slider values to fine-tune them (more digits after the decimal point will be displayed).


TERRAINS IN LUMION
The editable part of the terrain in Lumion occupies a 2048x2048m square. Beyond this, you will not be able to change the height or paint the landscape. When you load a heightmap texture it will stretch to the full extent of the 2048x2048m square.

If you load a standard JPG file, 100% black equates to a terrain height of 0m and 100% white is equal to a terrain height of 200m. In other words, each greyscale step (from 0 to 255) is equal to 0.78125m.

As for the height scale of imported heightmap textures, the RGB values normally range from 0 to 1.0, but if you create a 32-bit image in Photoshop (Image -> Mode -> 32-bits per channel), you can boost the whiteness (and the terrain height range) by up to x20. In other words:
RGB 0 to 1.0 in Photoshop = 0m to 200m in Lumion
RGB 0 to 2.0 in Photoshop = 0m to 400m in Lumion
RGB 0 to 3.0 in Photoshop = 0m to 600m in Lumion

Once you've created your heightmap, you'll need to save it as a 32-bit DDS heightmap in "32f" format using Nvidia's DDS plugin for Photoshop:

TIP: You can also import your own terrain as a DAE/FBX object and apply a Landscape material to it. This allows you paint on it just like the "native" terrain in Lumion.


MOVIE SECTION TIPS
Duplicate camera keyframes: To duplicate a camera keyframe, edit a clip by double-clicking on it, then select one of the thumbnail images and press CTRL + C to duplicate it.


HOW TO IMPORT MOVE/ROTATE/SCALE ANIMATIONS FROM 3DS MAX
1) Time configuration -> Frame Rate -> PAL
2) Animate your object with move/rotate/scale keyframes.
3) File -> Export...
4) FBX format -> Preset -> AutoDesk Media & Entertainment
5) Import the FBX file in Lumion -> "Animation On"
6) Place the object anywhere in your scene to see the animation.


WHERE ARE MY LUMION PROJECTS AND IMPORTED MODELS SAVED?
As with any other data on your harddrive, we recommend regular backups of the following folders:

  • Documents/Lumion/Scenes: All scenes saved in Lumion Basic/Ultimate SP1/SP2 (2 files per scene)
  • Documents/Lumion/Library: Models imported in Lumion Basic/Ultimate SP1/SP2 (up to 4 files per model)
  • Documents/LumionFree/Scenes: Scene files saved in Lumion Free (2 files per scene)
  • Documents/LumionFree/Library: Models imported in Lumion Free (up to 4 files per model)

Lumion is not (always) backwards compatible, so if you save a scene or an imported model in Lumion Basic/Ultimate SP2 you may not be able to open them in Lumion SP1.

Also, Lumion Free scenes can't be loaded in Lumion Basic/Ultimate.
