SAVE & LOAD CAMERA VIEWPOINTS

(CTRL) + (1) (2) … (9) (0): Use this function to save up to 10 camera positions

(SHIFT) + (1) (2) … (9) (0): Load previously saved camera viewpoints The saved slots are also

available as easily accessible thumbnail images in Photo mode

BACKGROUND RENDERING

Lumion always renders movies and image sequences in the background, so that you can

check your emails etc while it is rendering

IMPORTANT: You need to wait for the first frame to finish before you switch to other

windows Avoid moving/re-sizing/minimizing the Lumion window while it is rendering, and do

not click on the Show Desktop button in the lower right corner of Windows This will reset the

exposure in Lumion which means that the video has to be rendered from scratch again

IMPORTING & UPDATING MODELS

Edit Materials -> (CTRL) + Reload Model and re-apply materials (new file) button: If the

name or location of an exported object file (DAE, FBX etc) has changed, this button allows you

to manually select the location/name of the file:

Edit Materials -> (ALT) + 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 ALT 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)

Trang 4

Import model -> 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 If you set the Scale slider to 1.0 in

Lumion, and the surface is aligned with the world axes, each texture "tile" will cover an area of 1x1m in Lumion Rectangular textures will be re-scaled so that they are square in Lumion

Load/Save material set function: You can now save materials in a scene to a file, and

automatically apply those materials to another imported model provided that they use the

same material names in your 3D modelling application (Edit materials -> Load/Save material

set buttons):

SELECTING, COPYING, MOVING AND ALIGNING OBJECTS

(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

Place object mode -> (CTRL) + (Z) + Left-click: Combined operation of above mentioned Place Object Modes Randomly place 10 copies of the currently active object library

model with +/-0 to 50% random scale

(F12): Drag Model mode lets you move objects by clicking directly on them 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): This function will make objects that you are moving or placing in your scene snap to the Lumion terrain while ignoring all other object types

(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 (F) for "Flatten" -> Move the

object(s) to make them adapt to the surface angles of other objects This function only works

on surfaces that are facing the sky, i.e less than 90 degree angles

Trang 5

(SHIFT) + Move selected object(s): Press shift while dragging selected objects to move them horizontally with snapping turned off

(SHIFT) + Rotate/Rotate Pitch/Rotate Bank selected object(s): Press shift while rotating

objects to temporarily turn the 45 degree angle snapping off

(K) + Rotate/Rotate Pitch/Rotate Bank selected object(s): Press K while rotating objects to make all of the objects face the mouse cursor

(CTRL) + "Same height" command: The selected objects will be placed at the same height as the object you clicked on (CTRL)-select objects -> Context menu -> (Click on the 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 object that you clicked on to execute the command and the object that is furthest

away from that object (CTRL)-select objects -> Context menu -> Click on the selection icon

of one of the selected objects -> Transformation -> Space)

"Align" command: This command lets you centre selected objects so that their pivot points

are at the same position (CTRL-select objects -> Context menu -> Transformation -> Align) If you need to move or manipulate one of the overlapping objects, place the mouse cursor over the small overlapping object selection icons and use the mouse wheel (or the Arrow

Up/Down keys) to toggle between the objects

(L): Scale model

(R): Rotate Heading

(P): Rotate Pitch

(B): Rotate Bank

SPOTLIGHTS

Trang 6

To preview shadows from spotlights in Build mode:

1) Select the spotlights in Build mode to temporarilly turn on real-time shadows

To preview shadows from spotlights in Movie/Photo mode:

1) Go to the Photo or Movie section

2) Apply a Global Illumination effect (New effect -> World tab -> Global Illumination)

3) Click on Preview spotlight GI and shadows in the effect panel

4) If you want to view the shadows in Build mode, click on the Build with effect button in the

top left corner

In Light Properties -> Optimize for, choose what is most important for each light:

 Accuracy: The shadows are updated every frame (Slow!) Every time you add a light

with Accuracy turned on, the entire scene has to be rendered once more Add 10

lights and the scene has to be rendered 10 times more every frame Each light uses a 2048x2048 pixel shadow texture

 Memory: The shadow from the light uses a static 128x128 pixel texture which is not updated (Fast, very low memory usage)

 Speed: The shadow from the light uses a static 512x512 pixel texture which is not updated (Fast, moderate memory usage)

To reduce render times, we recommend that distant lights (e.g street lights) in your scene use

either the Memory or the Speed option, so that the shadows are not updated every frame If your graphics card has enough memory, the best option is Speed

You would only ever use Accuracy for your lights if something that casts shadows is moving

near the light (a car driving past a street light for example) Or if the light itself moves/rotates

(stage lighting for concerts for example) Or if you need high-resolution shadows in certain

areas (typically close-ups of interiors)

SHADOW ARTIFACTS (BANDING, FLICKERING, LIGHT LEAKAGE)

Shadows in Lumion are added on top of all surfaces with an offset The reason an offset is

needed is that the shadows will otherwise flicker (or display banding artifacts) when the

shadows are very close to surface If the offset is set too high, furniture (as an example) will

appear to hover above the floor In reality the furniture is not hovering of course, but the offset shadows give the illusion of it

Trang 7

It's difficult to get the offset right as the optimal offset varies from scene to scene, depending

on the sun position and the camera position For that reason, you have to add the Shadow

effect to your clip and experiment with the Shadow correction and Shadow Slope sliders until

the artifacts are gone

The Shadow correction slider controls the offset directly whereas the Shadow Slope slider is

used to prevent light leakage through models

UPDATE SUN, SKY, LIGHTING, CLOUDS AND REFLECTIONS

(U): If you press the U key, the sun, sky, lighting, clouds and 360 degree reflection texture will

be updated This is often necessary if you switch between Build/Movie/Photo mode and the

sun is in different positions If you keep the U key pressed in Photo/Movie mode, the Cloud

effect will be rendered in (almost) final render quality This is useful if you want to see what the

clouds will look like while adjusting the cloud sliders Bear in mind that the Volume Clouds

effect has to be rendered in 3 star quality to see what these clouds will look like in final render quality

GLOBAL ILLUMINATION

You must render images/videos with the Global Illumination effect in 3 star quality If you

render it in 1 or 2 star quality, the lighting will appear to flicker and you will only see a pixelated preview of the global illumination lighting on your renderings

VOLUME CLOUDS

You must render images/videos with the Volume Clouds effect in 3 star quality If you render it

in 1 or 2 star quality, you will only see a pixelated preview on your renderings, and the clouds will appear to move and change shape as the camera moves

REFLECTIONS IN LUMION

There are 2 types of reflections in Lumion:

1) Planar reflections (New effect -> World -> Reflection):

This Movie effect allows you to specify up to 10 reflection planes in your scene Any model

surface which is co-planar with a specified reflection plane in your scene will have accurate

reflections This is ideal for mirrors, marble floors etc The effect includes a Threshold slider

which allows you to adjust the distance at which nearly-co-planar surfaces will be included in the reflection plane The tradeoff is accuracy but it's usually not noticeable Please note that if you have some nearly co-planar surfaces that you want to assign a single reflection plane to, you need to assign the plane to the surface which is closest to the camera so to speak

Every time you add 1 reflection plane, Lumion has to mirror all models & render the entire

scene once more For that reason, try to use as few reflection planes as possible:

2) Projected reflections:

Projected reflections in Lumion rely on a single 360 degree panoramic reflection texture

which is projected onto any reflective materials that are not using planar reflections The

projected reflection method is only an approximation and will never provide as realistic

reflections as the planar reflection effect above In Lumion 3, add the Lights -> Utilities ->

Reflection control object to your scene to specify the position where the 360 degree

panoramic reflection texture should be rendered at

Trang 9

If you do not add this object to your scene it will be placed a few hundred meters above the

terrain If you are rendering interiors, the best position for the Reflection Control object is

often near the camera position Bear in mind that you can also animate this object with the

Move/Advanced Move effects in the Movie section

HOW TO PREVENT SURFACES FROM FLICKERING/DISAPPEARING

If you notice that surfaces flicker or disappear when moving the camera, add a Standard

material to the surface that you want to be on top Then adjust the Depth Offset slider in that material but avoid extreme Depth Offset values - you should only adjust it a little bit, until the

flickering stops (The best method is of course to make sure that your surfaces are offset a bit

in your 3D modelling application, so that the flickering is less likely to occur in the first place)

Trang 10

OBJECT COLOURS

Objects -> Edit properties -> Object Color allows you to change the colours of many of the

Transport, Indoor and Outdoor models, e.g furniture and vehicles Note that you can also

copy-paste a colour from outside Lumion to any color selection window in Lumion Simply

press CTRL + C to copy a highlighted hexadecimal colour in text format, eg, "ff0000" (red),

and press CTRL + V to paste this colour onto the solid bar on the right side of the color

selection window

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, but will 'fade out' to 0m

along the edges to blend with the endless terrain outside the editable area

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

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:
