OVERVIEW

OVERVIEW Game engines are revolutionizing professional workflows, allowing designers and

engineers to visualize and interact with their creations in virtual reality, accelerating

real-time design decisions. One of the biggest challenges though for CAD users is

importing their work into a game engine with as few mouse clicks as possible – we

have a solution and created the Radeon™ ProRender Game Engine Importer, a tool

that allows you to easily import your geometry and materials using Radeon™

ProRender from Dassault Systèmes SOLIDWORKS® to view them in VR.

Radeon ProRender for SOLIDWORKS and Radeon ProRender Game Engine Importer for Unreal Engine These steps explaining how to use Radeon™ ProRender for SOLIDWORKS are needed to create the

assets to import into the Unreal® Engine. This tool can process post render imaging effects, apply decals

and finetune scene details visible in backgrounds and lighting. For more information on to use Radeon™

ProRender for SOLIDWORKS, go to pro.radeon.com/en-us/software/prorender/ to view the user guide.

STEP 1: Open Model in SOLIDWORKS

With the Radeon™ ProRender add-in installed, launch SOLIDWORKS® and open your model. Note that

AMD’s longstanding support for RealView and Order Independent Transparency (OIT) yield a high-quality

rendering of the CAD model. For physically-based photorealistic ray-tracing, AMD offers the free

Radeon™ ProRender add-in for SOLIDWORKS 2016 and 2017.

STEP 2: Set Render Properties

Open the Radeon™ ProRender add-in and set the rendering properties in the “Properties Page” tab.

Note that the setting for “Mesh Quality” will impact game engine and VR performance, and the settings

for “Render Quality” (especially “Max Ray Bounces”) will impact rendering speed and should only be set to

higher values when rendering highly reflective or transparent materials. Make sure that GPU rendering is

selected. When finished, click the green check icon to save the Radeon™ ProRender Properties.


GETTING STARTED

3

STEP 3: View Render in Rendering Window

Then click the “Rendering Window” tab. The progressive rendering will begin immediately after the

model is loaded into Radeon™ ProRender, and can be limited by either time or the number of rendering

passes (iterations.) The angle of the viewport can be modified in real time by checking the “Orbit

Camera” box and holding the middle mouse button while dragging the mouse. Zoom the camera in and

out with the mouse wheel. Any change to the camera view initiates a fresh pass of the rendering. The

ProRender rendering is physically correct and photorealistic.


GETTING STARTED

4

STEP 4: Apply Decals

Decals (from standard graphics formats like PNG, JPG, TIFF, and DDS) may be applied to bodies or faces

of CAD parts and manipulated with multiple parameters. Applying decals will instigate a new rendering

pass using the current ProRender settings.


GETTING STARTED

5

STEP 5: Export Radeon ProRender Scene

From the menu (upper left corner) of the Radeon™ ProRender window, choose “Export ProRender

Scene”, which places an .frs file in the disk location of your choosing. The .frs file can be imported into

Unreal Engine for VR visualization and interactivity with the Radeon™ ProRender Game Engine Importer.

Radeon ProRender Game Engine Importer for Unreal Engine

STEP 1: Launch Unreal Engine

Launch Unreal Engine 4.15.3 from the Epic Games Launcher. Select the “New Project” tab and choose

the “Virtual Reality” Blueprint template and the “With Starter Content” option selected. By clicking

“Create Project” you will now enter the Unreal Editor.

Note: Radeon™ ProRender supports the following Unreal Engine versions: 4.15.1, 4.15.2, 4.15.3.


GETTING STARTED

1

STEP 2: Open Editor Window

Using the Content Browser in the lower left corner, double click in on the “VirtualRealityBP” folder…

…then double click in on the “Maps” folder…

…then select the “MotionControllerMap”, which will open in the Unreal Editor window.


GETTING STARTED

2

STEP 3: Verify Radeon ProRender Plug-in Install

Verify that the Radeon™ ProRender plug-in is installed and enabled by clicking “Edit…Plugins” from the

Unreal Editor toolbar, then “Importers” from the list of plugin categories. “RprsImporter” should be

installed and enabled (“Enabled” must be checked.)


GETTING STARTED

3

STEP 4: Import Radeon ProRender Scene

In the “Content Browser” pane in the lower left corner of the screen, click the “Import” button, and

choose any Radeon™ ProRender scene, which is a file with the “.frs” file extension.


GETTING STARTED

4

STEP 5: Verify Assets

To activate physics interactions in Unreal with the Radeon™ ProRender object, set the “Combine Levels”

option to “All” in the RPRS Options dialog. The duration of the import process varies with the number of

materials contained in the Radeon™ ProRender object. The imported Radeon™ ProRender asset opens

by default in Unreal’s Blueprint editor in a separate window on top of the main Unreal Editor.

All attributes affecting material appearances (color, texture, refractivity, reflectivity, specular properties,

etc.) assigned in the CAD application are automatically mapped into Unreal. The Radeon™ ProRender

material appearances are also automatically inherited by the asset’s Unreal reflection map.


GETTING STARTED

5

STEP 6: Open Blueprint Editor

In the Blueprint Editor, select the “CombineAll” static mesh component in the Components pane in the

upper left corner.


GETTING STARTED

6

STEP 7: Simulate Physics

With “CombineAll” in the Components pane still highlighted, move to the Details pane on the right side,

navigate to the Physics section (just below Materials) and check the “SimulatePhysics” option.


GETTING STARTED

7

STEP 8: Compile the Blueprint

By pressing the tool bar at the top of the Blueprint Editor, “Compile” the Blueprint. The icon on the

Compile button will switch from a question mark to a green check.


GETTING STARTED

8

STEP 9: Asset Positioning

Minimize the Blueprint Editor and switch back to the Unreal Editor. The imported Radeon™ ProRender

asset will be located at the 0,0,0 position of the Unreal coordinate plane, which places half of the object

above the floor and half of it below. Raise the imported Radeon™ ProRender asset above the Unreal floor

by selecting and dragging the blue arrow up, or by entering a value (in centimeters) in the Z location of

the “Transform” section of the “Details” pane for the imported Radeon™ ProRender object.


GETTING STARTED

9

STEP 10: Enable VR Viewing

With SteamVR™ running (and headset and controllers tracking), “Play” the experience from the Unreal Editor toolbar in “VR Preview” for viewing through an HTC VIVE™ or Oculus Rift VR headset. (Note that there is a drop-down selector associated with the “Play” button. “VR Preview” must be selected from the list.)

Teleport around the scene using the thumb pad of the left or right HTC VIVE controller. Push and hold

the thumb pad to set the distance of the teleportation, and rotate your thumb around the thumb pad to

indicate which direction the player will be facing when the teleportation is complete. Release the thumb

to invoke the teleportation.


GETTING STARTED

10

Pulling the trigger of either hand controller will invoke the “grab” action for that hand. The blue blocks in

the scene can be picked up and manipulated with physics interactions. A clenched hand can be collided

with the imported Radeon™ ProRender asset, so the Radeon™ ProRender object can be toppled and

moved in a limited fashion. For more advanced interactions such as grabbing the Radeon™ ProRender

object, more advanced scripting is required in the Blueprint for that object.
