What is Unreal Engine?
▪ Video game engine released in May 1998, currently in
the 4th version, released in 2014
▪ Used more than just for video games, including:
▪ Animated film
▪ VFX in film production
▪ Virtual reality and augmented reality app
▪ Virtual product photography
▪ Architecture and construction
▪ Can be used for free, but charge a license fee of 5%
revenue when you make more than $3000/quarter

VFX film-making using Unreal real-time renderer
Animation produced by 1 person without the need for a render farm
Useful for architecture and interior design visualization as well

What are some common 3D file formats?
▪ Commonly used formats include .fbx and .obj (for static objects) –
“the .jpg and .png of Unreal world”
▪ Common application for making 3D content includes Autodesk
Maya, Autodesk 3ds Max and Blender
▪ 3D software project file:
▪ Maya - .ma, .mb
▪ 3ds Max - .max, .3ds (old format)
▪ Blender - .blend
▪ Unreal - .uproject, .uasset (convert to this when imported)

Invert Middle Mouse Pan
Allows you to pan around
like in Maya or SparkAR

- Left/right mouse drag
- Alt + Left mouse drag
- Alt + Right mouse drag (zoom)
- Middle mouse pan
- Middle mouse scroll (zoom)
- Ctrl+Z / Ctrl+Y -> Undo/Redo
NAVIGATING THE VIEWPORT
- W -> Select and translate
- E -> Select and rotate
- R -> Select and scale
- F -> Focus on selected object
- G -> Hide non-3D models
- H / Ctrl+H -> Hide/Unhide object
(can be revealed again
at World Outliner)
World Outliner
*note: these are Windows shortcuts, Mac version might varies

Starter Pack comes with 3 different levels
Try going into ‘StarterMap’
ADDING / SAVING LEVEL

ADDING / SAVING LEVEL
The Default level comes with a light source and sky
Select File > New Level and
click on Default

GEOMETRY TOOLS
addictive, subtractive
static mesh
geometry editing

GEOMETRY TOOL
Drag a Geometry shape
from the Mode Panel
Edit the height, width, sides,
etc on the Brush Settings
under Details Panel

GEOMETRY TOOL (ADDICTIVE, SUBTRACTIVE)
Things to note for 2 or more geometries:
• Addictive adds on
• Subtractive takes away
• The order is important in determining which one goes
first (for 2 or more geometry)

GEOMETRY TOOL (STATIC MESH)
Try creating something out of 4 or more geometry using
Addictive/Subtractive
Convert into a static mesh to be
used as a normal object/actor

GEOMETRY TOOL (GEOMETRY EDITING)
Go to Geometry Editing and select the
Vertex, or Surface or Edge, Optimize
when done
Very rudimentary compared to Maya or
Blender, but useful for basic layout of
your installation

Drag the object(s) you want to use as
foliage here
FOLIAGE
Edit the modifier to randomize the
object being painted
Density, Scale X, Align Max Angle, etc
Use this to select individual foliage

IMPORTING OBJECTS
blender
material & texture
object with more than 1 parts
physics

Use Blender to export the desired object by selecting them together as export as either .fbx or
.obj (.fbx is recommended as it can hold more information)
Tick ‘Selected Objects’ before exporting
IMPORTING OBJECTS (BLENDER)
If the 3D model does not come in .fbx or .obj format:

Drag the .fbx file into the Content
Browser and click on Import
Deselect ‘Skeletal Mesh’
Select ‘Do Not Create Materials’
and deselect ‘Import Texture’ if
there is no texture associated with
the model
Right-click in the Content Browser to
create a new Material for the object
you just imported
Import the .png texture as well by
dragging and dropping the .png file
IMPORTING OBJECTS (MATERIAL & TEXTURE)

Right click on the Material and
rename it, double-click on the
Material to go into the Material tab
IMPORTING OBJECTS (MATERIAL & TEXTURE)
Click and drag ‘Base Color’ and type
‘TextureSample’
Select the texture and click Save
above when you are done
Drag and apply the Material
under the ‘Materials’ section

Select all the individual components and drag it to the Viewport
IMPORTING OBJECTS (OBJECT WITH MORE THAN 1 PARTS)
Right-click on the sub-parts and ‘Attach To’ the main
part, now when you move the main part, it affects
the sub-parts as well

Select ‘Simulate Physics’
IMPORTING OBJECTS (PHYSICS)
Double-click on the object/actor to open their property tab
If Simulate Physics is greyed out:

1. Click on Collision > Complex Collision
IMPORTING OBJECTS (PHYSICS)
2. Select Collision >
Auto Convex Collision
3. Click ‘Apply’
4. Save and close tab, Simulate Physics should
be possible now

BUILDING LIGHTING & SCREENSHOT

BUILD LIGHTING AND SCREENSHOT
Select your Lighting Quality, the
higher it is, the longer to build
Click on ‘Build’ afterwards
Select ‘Simulate’ to see the
physics in action

BUILD LIGHTING & SCREENSHOT
Click on the camera icon
Increase the number to increase the height and
width of the screenshot
Select ‘High Resolution
Screenshot’
