Installation

Tutorials

Customising key mappings

Navigate to the Input folder, found in Redprint > FirstPerson > Input, where the IMC_FP file is located. Open this file and the settings window will pop up.

All the actions which can be customised are listed below:

  • Jump
  • Move
  • Look
  • Fly
  • Run
  • Drone Toggle
  • Pause Toggle
  • Interact

You may change the default key mappings to your preference. For example, If you would like to change the Drone Toggle from X to Y, click on the drown down button and search for Y. Select Keyboard Y and save the file. It will now be updated to use the Y key.

There is controller support for all gamepad input systems supported by UE by default.  

Importing your project

Start by duplicating the BaseMap01 level file, found in Redprint > Maps. Rename and open the newly created file. The list below shows the existing folder structure present in the file:

  • 00_GlobalLighting – This includes the SunSky system used to dynamically change the time and sun location in game and should not be removed. You may edit the position and change the settings to match the location of the project.
  • 00_Player – This includes the PlayerStart location and should not be removed. You may edit the position to locate where the user will start from when opening the project.
  • 01_Architecture – Includes a cuboid with a spiral staircase for testing, this can be replaced with your own project.  
  • 02_Context – Includes a basic floor to ground the player. This can be removed with your own geometry.

Import your project geometry (3D models) into UE. The folder structure below is recommend to get you started but you may customise it to your needs. The only folder needed for Redprint to run is the Redprint folder.  

There are a number of ways to import content into UE and the list below details the most common methods:

  • Via the Content Browser, right-click to import, and choose the appropriate file format (like FBX, OBJ, or Alembic). 
  • Via Datasmith with a supported design application.
  • Via the USD Stage Manager to import USD files.

Editing the UI / Menu

Project meta data such as Name, Version, Data and Credits can be changed by opening the ProjectMetaData file, found in Redprint > UI > Blueprints and opening the Default Values tab.

The information panel text can be edited by opening the MainInformation file, found in Redprint > UI > MenuWidgets.

The cover image, named CoverInfo, located in Redprint > UI > Assets can be replaced with your own imported image. If you rename the texture, make sure to select it by clicking on the image in the MainInformation file and selecting the new texture.

The video playing in the background of the main menu can be replaced by placing the video file into the Movie folder where your UE project is located. Then, create and name a new File Media Source asset in the content browser and locate your video file and save it.

Navigate to Redprint > UI > Assets and open the media player MP_BG file. Select your video from the list and save. Next, open the MainMenu_01 file, located in Redprint > UI and open the Level Blueprint. Select your video as the Media Source from the drown down menu and save.   

To replace the logo, make sure it has an aspect ratio of 1:1 and import it. Navigate to Reprint > UI > MenuWidgets and replace the image, in both MainMenu and PauseMenu, with the imported file from the drop-down menu.

Packaging & Exporting

To package the project into a standalone project that can run without the editor, open the Packaging Settings from the drop down list on the Platforms button.

  • Select Shipping for the build configuration
  • Check Full Rebuild if you are packaging for the first time
  • Change the Game Splash and Game Icon images which can be found under Project Settings > Platforms > Windows* (*select the platform for which you are packaging for)

Hit the Package Project button on the drop down list and depending on your system specs, a folder with your project will be exported ready to view and share with clients in a matter of minutes.
