Data Management And Data Tables

Data Tables are now used to store data for the UI3. This moves some of the data out of the Info Map. It also gives a way to save and re-use data entered.

This is a brief overview about how data tables are used.

UI3 Interface Layout Design

• Layout Design - how the UI is arranged
• Design Settings - text format, icon appearance, and colors.

This section explains how to use them.

Designer

The Designer shows objects and their variations in a table like widget.

• Modify objects that are in multiple locations or difficult to select
• External blueprint tools like the Modular Kitchen Builder or the Interactive Doors

Variation Actor

The Variations Actor is the link between the UI3 and the objects placed in the scene. It can

UI3 Feature Widgets Overview

Overview of all available feature widgets in the UI.

In order of their appearance in the Info Map.

Some features have their own detailed page.

UI3 - Scene Settings

Scene Settings affect the quality and performance of the scene.

They also control the movement of the player character and the player camera control.

UI3 Input Controls & Game Modes

The Game Mode defines the type of game (Touch, VR) for the scene and what input devices are used to control it.

Some of the content is slightly different between versions.

VR Projects

This will give you a brief overview of what is required to run the UI3 with a VR headset.

The demo project is optimised for PC and may run poorly in some VR environments. Your project needs to be performing well if you want to use it in VR!

This is not a complete guide for VR in Unreal Engine. Follow the links provided for better guides.

Connect UI3 To External Blueprints

How to connect to other blueprints that are not part of the UI3 project.

Cost Tracking

When objects in the scene are modified, their costs will most likely change. Cost tracking allows to keep track of these changing costs.
