Update to the latest Unreal Engine

Unreal Engine 4.21

Support the Niagara platform and improve availability

Epic strives to bring industry-leading effects creation tools. Therefore, in the latest version of Unreal Engine, Niagara has an expanded feature set, significantly improving the quality of life. Currently, Niagara effects are supported on the Nintendo Switch.

Animation templates in Niagara

Now users can create 2D graphic patterns or virtual 2D structures in component scripts. Create incredible effects such as displaying scene depth, color and normal information with the Scene Capture Actor and use it to reconstruct the environment in Niagara's granulation system with potential and dynamism. I paint with light.

Upgrading Skeletal Mesh Data Interface: Users can use many new features in the Skeletal Mesh Data Interface, allowing users to directly sample Skeletal Mesh peak data as well as access certain Bone or Socket on Skeletal Mesh.

Improve Particle Ribbon performance: The ribbon now creates ribbon geometry on the GPU instead of the CPU, improving overall performance.

GPU simulation support in Niagara: GPU effects Niagara influences are now supported on all non-mobile platforms.

Simplify the system and generate emissions: Niagara now includes user-friendly dialogs, capable of unprecedented system creation and scattering. Users can create new scatters and systems from a selection of templates when they want to speed up development and ensure the most practical.

Shake limit: This limit addresses the physical effects, the optional jump driver, including the calculation of potential energy. Now users can create dynamic, interesting effects such as producing particles with inherited velocities if energy exceeds the specified threshold.

Other striking changes

• Pixel Streaming (Earrly Access)
• Plugin Replication Graph
• System optimization & improved animation
• Improve time

Unreal Engine 4.20

Unreal Engine 4.20 brings over 100 great mobile optimizations for Fortnite on iOS and Android, marking a major change for developers in terms of game streaming and seamless gameplay optimization across platforms. Major enhancements include improved Android bug fixes, mobile images, Occlusion Query.

Occlusion Query hardware and software on mobile

Unreal Engine now supports Hardware Occlusion Query for both high-end iOS and Android mobile devices, running ES 3.1 or Vulkan with GPU. By default, Hardware Occlusion Query is enabled on any device that supports them.

Software Occlusion Query is an experimental feature that uses the CPU to select the original components in the scene. Because it uses a secure method, it should be compatible on all mobile devices.

Left - r.Mobile.AllowSoftwareOcclusion 1, r.SO.VisualizeBuffer 1; Right - The Occluder section

To turn on Software Occlusion Queries, follow these steps:

1. Activate r.Mobile.AllowSoftwareOcclusion 1.
2. Turn off r.AllowOcclusionQueries 0.
3. Set any original color to an Occluder by selecting 'true' LOD for Occluder Mesh in the Static Mesh Editor.

You can visualize the results in Mobile Previewer when using High-End Mobile and turn on r.SO.VisualizeBuffer 1.

Material Statistics platform

Quickly configure and optimize Materials with the new Platform Stats window in Material Editor! You can now view statistics of various Shader platforms and quality levels. For mobile platforms, Unreal uses the offline Shader compiler to provide more accurate instructions with texture usage information.

Improved Android debug

Repeat and debug on Android without having to repackage the UE4 project. When compiling Android, Unreal creates a Gradle project file compatible with Android Studio. Users can set breakpoints in C ++, Java code and use Android Studio to open patches. The software also allows users to change C ++ sources and recompile. If you start a new debug session, Android Studio will receive changes and quickly upload new shared libraries to your device.

Improved Mobile Landscape

Making terrain on mobile becomes more interesting thanks to the infinite Landscape Material layer warehouse. Although 3 is the optimal number of layers, Unreal still supports any number of layers the user wants as long as there are enough Texture Sampler.

You can now use the Feature Level Switch Material nodes in Landscape Materials to create a Landscape Material for all platforms.
