Motion Matching in Unreal Engine is a query-based animation pose selection system. Contained within the Pose Search plugin, you can use the Motion Matching Animation Blueprint node as a dynamic alternative to State Machines, or Blendspaces. Unlike traditional animation systems, Motion Matching can make informed animation pose selections from a set of animation data, to create a responsive and reactive animation system, without the need to set up transition or blending logic between Animation Sequences. Lear how to set it up and download the sample project to get started. https://dev.epicgames.com/documentation/en-us/unreal-engine/motion-matching-in-unreal-engine#createaposesearchschemaasset

Body motion capture is the process of capturing the movements and actions of a performer using specialized sensors, which are then translated into digital data that can be used to animate a virtual character or object. There are several solutions for body motion capture that offer a ton of value at different price points. The most common industry-standard suit is the XSens from Movella. There is also a brand new, low-cost option, “mocopi” from Sony and they just announced a studio mode. https://youtu.be/DgNbU-iT9j0?si=3BpHVWZYwB0DL-sq

One way you can improve the realism in your character's movement is to provide dynamic animations for items that they may be carrying or wearing. With AnimDynamics those pieces that you would expect to move around as you move in real life (hair, necklaces, bracelets, swords, pouches, etc.) will bounce around and move while your character moves. For advanced and professional animators looking to make the transition from Maya or another DCC to animating in Unreal Engine this session is a must watch. https://youtu.be/z1OmjnFZUgc?si=hzB8HxrJrm-7Sw1y

The target device for your UE application has a finite amount of resources available, both for keeping objects in memory and processing them. When building your application, you must decide what to spend those resources on. You should familiarize yourself with your device's capabilities in terms of the speed, threads, and bandwidth for your CPU and GPU, as well as your device's memory, graphics memory, and available disk space. High-resolution textures require a lot of space, both to store on a device and in a device's texture memory, and larger textures require more pixels to render and process. While they can increase fidelity, there are diminishing returns to texture size given your device's screen resolution and the viewing angle of the texture. It is important to use the smallest texture possible to obtain the desired level of fidelity. https://youtu.be/OnL8oTWDJOs?si=3ncOipHkzh59FPAp

Compositing is the act of combining visual elements from different sources into a single image. In the visual effects industry, compositing a single frame is usually an offline process and can take some time. With compositing built into the engine, users can easily visualize green-screened scenes combined with CG in real-time. This is especially helpful for previsualization, which enables directors to get a sense of what the final scene will look like, or for offline compositors to use as a guide. Compositing will run both in-editor and in-game. Any Composure element can be added to a sequence to indicate that its output should be exported when rendering out the sequence using the Render Movie Settings dialog with the ComposureExport output format. https://dev.epicgames.com/documentation/en-us/unreal-engine/compositing-elements-reference-for-unreal-engine

When you add a video or image sequence, Unreal Editor automatically creates a Media Playlist to hold the video asset reference, visible in the Media Playlist section. This section also displays the references to the initial Media Source as well as the Media Path. This section also contains clickable icons you can use to Restart, Rewind, Play, Pause, Fast Forward, Open, and Close the playlist. The Open Media Plate button lets you open a media plate window with a flat-facing mesh that shows you more in-depth information about the media. In this window, you can also use the Previous and Next icons to access other media in your playlist. https://dev.epicgames.com/documentation/en-us/unreal-engine/the-media-plate-actor-in-unreal-engine

A complex level in Unreal Engine contains hundreds of detailed Static Mesh assets that combine together to build a virtual world. With this level of detail, it can become difficult to load a multi-kilometer level all at once. The Hierarchical Level of Detail (HLOD) system can be used to organize multiple Static Mesh Actors and combine them into a single proxy mesh and Material at long view distances. This helps reduce the number of Actors that need to be rendered for the scene, which reduces the number draw calls per frame and increases performance. This is especially useful when working with large open worlds. https://dev.epicgames.com/documentation/en-us/unreal-engine/hierarchical-level-of-detail-overview-in-unreal-engine

Unreal Engine (UE) comes with an integrated method that allows people to work together on their projects using version control software called Perforce. Source Control allows users on your team to share assets and code with one another, as well as providing a backup and history of changes so any files can be rolled back to an earlier version if something went wrong with the file. When working on a file the Editor will lock that file (this is known as Checking Out in Perforce nomenclature) so that other users cannot concurrently edit it. When the user is done with editing the file(s) they have locked, they check in, or commit those files, uploading the changes to the server and releasing the lock on the file. Learn more about Perforce from the recent talk at Unreal Fest. https://youtu.be/_cVYfufgziM?si=GUtiPvy5M5U1TDXR

Soundscape procedurally generates ambient sounds which are streamed as the player moves around the world. Once set up, the plugin manages and composes these sound systems autonomously and removes the need to manually create them. Soundscape uses Gameplay Tags as states. You can control these states using a Blueprint or C++ and Soundscape will respond automatically with the conditions you set. Explore soundscape and more tips on audio workflows for Unreal Engine https://youtu.be/xaMX_NEyLJc?si=WZ9xsyG8RXjy3bF1

Unreal Engine supports a variety of file formats for importing content into your project. FBX is a flexible file format that is owned by Autodesk and provides interoperability between digital content creation (DCC) applications. Some applications such as Autodesk Motionbuilder support the format natively. While others such as Autodesk Maya, Autodesk 3ds Max, and Blender support the format using FBX plugins. The advantages of the Unreal FBX Import pipeline over other importing methods are: - Using a single file format for Static Mesh, Skeletal Mesh, animation, and morph targets. - Importing multiple LODs and Morphs/Blendshapes in one import operation. - Importing Material and Texture assets, and automatically applying them to Static Meshes. https://dev.epicgames.com/documentation/en-us/unreal-engine/fbx-skeletal-mesh-pipeline-in-unreal-engine

Paper 2D is Unreal Engine’s system designed for creating 2D and 2D/3D hybrid projects. It provides tools to handle gameplay and animation specifically for 2D development, making it a great choice for developers interested in side-scrollers, platformers, or other 2D genres. The cornerstone of Paper 2D is the Sprite, a primary asset type. A Sprite is a static 2D texture that represents characters, objects, or elements within your project. These textures are created by extracting regions from a texture atlas or imported directly. Once set up, Sprites can be used for rendering, animations, and physics interactions. If you’re starting out, focus on understanding how to: -Create and import Sprites. -Animate your Sprites using Flipbooks (Paper 2D’s animation tool). -Integrate Sprites into your gameplay. https://dev.epicgames.com/documentation/en-us/unreal-engine/paper-2d-flipbooks-in-unreal-engine
