  20. 20. 20 GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class
  21. 21. 21 The GameInstance is a class who’s state persists switching of levels, game modes, pawns etc. Where classes like GameMode or PlayerController are being reset and data stored in those classes is removed. Any data that you want to keep beyond levels and matches, for example "what player did in specific moment so you can have consequence on other level" should be placed in the GameInstance. GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class
  22. 22. 22 The GameMode is the definition of the game, including things like the game rules and win conditions. It only exists on the server. It typically should not have much data that changes during play, and it definitely should not have transient data that clients need to know about. GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class
  23. 23. 23 The GameState contains the state of the game, which could include things like the list of connected players, the score, where the pieces are in a chess game, or the list of what missions you have completed in an open world game. The GameState exists on the server and all clients and can replicate freely to keep all machines up to date. GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class
  24. 24. 24 A PlayerState is the state of a participant in the game, such as a human player or a bot that is simulating a player. Non-player AI that exists as part of the game would not have a PlayerState. Example data that would be appropriate in a PlayerState include player name, score, in- match level for something like a MOBA, or whether the player is currently carrying the flag in a CTF game. PlayerStates for all players exist on all machines (unlike PlayerControllers) and can replicate freely to keep things in sync. GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class
  25. 25. 25 A PlayerController is the interface between the Pawn and the human player controlling it. The PlayerController decides what to do and then issues commands to the Pawn (e.g. "start crouching", "jump"). In some cases, putting input handling or other functionality into the PlayerController is necessary. The PlayerController persists throughout the game, while the Pawn can be transient. For example, in deathmatch style gameplay, you may die and respawn, so you would get a new Pawn but your PlayerController would be the same. In this example, if you kept your score on your Pawn, the score would reset, but if you kept your score on your PlayerController, it would not. GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class
  26. 26. 26 GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class The HUD is the base object for displaying elements overlaid on the screen. Every human- controlled player in the game has their own instance of the AHUD class which draws to their individual Viewport. In the case of splitscreen multiplayer games, multiple Viewports share the same screen, but each HUD still draws to its own Viewport. The type, or class, of HUD to use is specified by the gametype being used.
  27. 27. 27 GameInstance GameMode Pawn Class HUD Class PlayerController Class PlayerState Class GameState Class The Pawn Class is the base class of all Actors that can be controlled by players or AI. A Pawn is the physical representation of a player or AI entity within the world. This not only means that the Pawn determines what the player or AI entity looks like visually, but also how it interacts with the world in terms of collisions and other physical interactions. The Pawn represents the physical location, rotation, etc. of a player or entity within the game. A Character is a special type of Pawn that has the ability to walk around.

  39. 39. Things to keep in at the front of your mind: World Scale Getting the scale of your world correct is one of the most important things to help deliver the best user experience possible on VR platforms. Having the wrong scale can lead to all kind of sensory issues for users and could even result in Simulation Sickness. Objects are most easily viewed in VR when they are in a range of 0.75 to 3.5 Meters from the player's camera. Inside of UE4, 1 Unreal Unit (UU) is equal to 1 Centimeter (CM). This means that object's inside of Unreal are best viewed when they are 75 UU to 350 UU away from the player's camera when using VR. 39 Distance Distance in Unreal Units(UU) 1 Centimeter 1 Unreal Unit 1 Meter 100 Unreal Units 1 Kilometer 100,000 Unreal Units
  40. 40. Things to keep in at the front of your mind: World Scale You can adjust the scale of your world in the World to Meters variable that is located under World Settings in side of UE4. However exercise caution when adjusting the scale of your world as again, selecting the wrong scale could lead to a disconnection between the world and the user which could lead to simulation sickness. 40
  41. 41. Things to keep in at the front of your mind: VR Character Settings The setup for a character using a VR headset is slightly different than for a standard character. Things like character Height, Width, Speed, and Camera Location all need to be slightly modified to accommodate a VR character. 41
  42. 42. Things to keep in at the front of your mind: VR Character Settings Character Height & Width Character Height & Width should mimic real life measurements as much as possible. Using sizes that are too big or two small could ruin the emersion that you are trying to achieve. 42 Property UE4 Default Recommended VR Height: 192 CM 176 CM Width: 84 CM 68 CM
  43. 43. Things to keep in at the front of your mind: VR Character Settings Movement Speed VR movement speed is a difficult property to recommend a setting for because the movement speed that you choose will mainly be determined by the type of experience that you are trying to achieve. In the Elemental VR demo for example, the movement speed was cut to about 1/4 normal speed. 43 Property UE4 Default Recommended VR Movement Speed: 60 M/S 24 M/S
  44. 44. Things to keep in at the front of your mind: VR Character Settings Camera Location The VR camera needs to be positioned slightly lower than the base eye height to compensate for being at the characters eye level. 44 Property UE4 Default Recommended VR Base Eye Height: 180 CM 160 CM
  45. 45. Things to keep in at the front of your mind: Make sure your project is running at your HMD's target frame rate before you build or add anything to your world. 45
  46. 46. Things to keep in at the front of your mind: Check your performance constantly to ensure that you are hitting your VR performance targets. 46
  47. 47. Things to keep in at the front of your mind: ○ Maintain a very simplistic approach to making your content. ○ Minimize complex shaders as best possible. ○ Add detail to the mesh within reason in lieu of relying of complex shaders for surface details. 47
  48. 48. Things to keep in at the front of your mind: LOD's and aggressive culling are a must to ensure that you are hitting your VR performance targets. 48
  49. 49. Known issues and possible workarounds: Screen Space Reflections(SSR) SSR will work in VR but not give you the results that you want and instead you should look into using reflection probes. 49
  50. 50. Known issues and possible workarounds: Normal Mapping Issues When viewing Normal maps on objects in VR, you will notice that they do not have the impact that they might have once had. This is because normal mapping does not account for a binocular display or motion parallax. Because of this, Normal maps will come out looking flat when viewed with a VR device. To get around this, you can do one of two things. 50
  51. 51. Known issues and possible workarounds: Parallax Mapping Parallax mapping takes Normal mapping to the next level by accounting for depth cues, Normal mapping does not. A Parallax mapping shader can better display depth information, making objects appear to have more detail than they do. This is because no matter what angle you look at, a Parallax map will always correct itself to show you the correct depth information from that view point. The best use of a Parallax map would be for cobblestone pathways and fine detail on surfaces. 51
  52. 52. Known issues and possible workarounds: Tessellation Shader Displacement Tessellation Shader Displacement will displace 3D Geometry in real time by adding details that are not modeled into the object. Tessellation shaders do a great job of displaying information because tessellation shaders actually create the missing detail by creating more vertices and displacing them in 3D Space. 52
  53. 53. New Project Settings: When creating a new project for VR it is best to create a project that uses the Mobile / Tablet setting with Scalable 3D or 2D and No Starter Content. If you need content you should port / import only what you need and not everything you have. 53
  54. 54. Launching VR Preview: Testing out your VR set is very straightforward, simply select “VR Preview” from the Play dropdown button. By default the head tracking will work right away without any changes to your existing project or template. 54
  55. 55. Using VR in Blueprint: Using VR in Blueprint is very straightforward. You will need a Camera Component and optionally one or two Motion Controllers Components. By default your Camera is already set up for HMD support, if you wish to disable rotation changes from the HMD you can disable “Lock to HMD” in the Component’s properties. 55
  56. 56. Performance Considerations: For the VR experience to feel smooth, your game needs to run on 75 hz (Oculus DK2) or even 90 hz. (HTC Vive and Oculus CV1) depending on the device. To see the current framerate type in “stat fps” or “stat unit” (for more detailed breakdown) in your console when running the game. 56
  57. 57. GPU Profiling: To capture a single frame with GPU timings press Ctrl+Shift+, or type in “profilegpu” in the console. This command dumps accurate timings of the GPU, you will find that certain processes are a heavy burden on the framerate (Ambient Occlusion is one common example) when using VR. The GPU Profiling & Performance and Profiling docs are a good place to learn about profiling your game. 57
  58. 58. Instanced Stereo: The latest 4.11 release introduces Instanced Stereo Rendering, check the video below for a comparison video of how that works. “Basically, we’re utilizing hardware instancing to draw both eyes simultaneously with a single draw call and pass through the render loop. This cuts down render thread CPU time significantly and also improves GPU performance. Bullet Train was seeing ~15 – 20% CPU improvement on the render thread and ~7 – 10% improvement on the GPU.” – Ryan Vance. 58 To enable this feature in 4.11 and above, go to your Project Settings and look for “Instanced Stereo” under the Rendering category.
  59. 59. Disable Heavy Post-Processors: Due to the demanding requirements of VR many of the advanced Post Processing features that you normally use should be disabled. To accomplish this you will need to do the following in your level. • Add a Post Process(PP) volume to your level if there is not already one there. • Select the PP volume and in the Post Process Volume section enable the Unbound option so that the settings in the PP volume will be applied to the entire level. • Expand the Settings of the Post Process Volume and then go through each section and disable any active PP settings by enabling that property by clicking on it and then set the value from the default, usually 1.0, to 0 to disable the feature. • When doing this you will not need to hit every section and set all the properties to 0. Instead first disable the really heavy hitting features like Lens Flares, Screen Space reflections, Temporal AA, SSAO, and anything else that might have an impact on performance. • While a lot of the features are disabled by setting things in your .INI this ensures that nothing will happen to performance if someone deletes the .INI by mistake. 59
  60. 60. Static, Stationary and Dynamic Lighting: You should always use Static lighting and lightmaps when making a VR project as this is the cheapest option to render. If you need to use dynamic lighting make sure to limit the amount of dynamic lights to as few as possible and make sure that they never touch one another. If you have an outdoor scene set your directional light to dynamic instead of stationary and then turn on Cascading Shadow Maps and set then adjust the settings to be as low as possible while still giving you shadows. This is going to take a lot of trial and error to get correct. 60
  61. 61. Fake shadows if you can: Using things like fake blob shadow drop to simulate dynamic shadows are a good general rule in order to keep VR project running at frame. 61 Blob shadow example. Image by Eric Chadwick
  62. 62. VFX in VR: Some VFX techniques like using SubUV Textures to simulate fire or smoke do not hold up well when viewed in VR. In many cases it can be more desirable to use static meshes emitters instead of 2D sprite particles to simulate VFX's like explosions or smoke trails. Near field effects, or effects that happen very close to the camera can work well in VR but only when the effects are made up of Static Meshes particles. 62
