Rig and add skeletal animation to your 2D characters with the new 2D Animation system and tools.
Now you can import your layered Photoshop file into Unity (make sure 2D PSD Importer is installed).
In the Sprite Editor you will find tools for bind-pose editing, bone creation, manual mesh tessellation and skin-weights painting. A runtime component ties this all together to drive sprite deformation.
Our goal is to enable you to create lively animations in a super-efficient way directly in the Unity Editor.
You can also add inverse kinematics to your 2D animated character with the 2D IK package.
Let us know what you think in our dedicated Forum.
SVG Importer与许多矢量图形标准（如渐变、填充、虚线或圆角）以及许多其他Unity 2D工具兼容。
The new Animation Rigging package gives you more artistic control over your animations. You can use a set of predefined animation constraints to manually build a control rig hierarchy for a generic character. At runtime, rig constraints are converted to a list of Animation jobs that are appended as post-process operations to the controller PlayableGraph.
You can now sculpt complex shapes from any 3D model, position detail meshes, paint in custom lighting or coloring, and blend textures across meshes directly in the Editor. Compatible with Unity since 2018.1, Polybrush is now available via the Package Manager and includes a Mesh and Prefab scattering mode.
The Profile Analyzer complements the Unity Profiler’s single-frame analysis by adding the ability to analyze multiple frames at once. This is useful when it’s important to have a wider view of your performance, such as when considering upgrading your Unity version, testing optimization benefits, or reviewing your development cycle.
A new physics system is written using the C# DOTS framework and leverages the Burst Compiler and C# Job System to deliver high-performance simulations. By using a stateless design with no caches, the solver is much simpler, allowing us to build a more network-friendly physics system that can be easily extended, tweaked, and modified to fit your production needs.
With the VFX Graph you can configure reusable next-generation effects, ranging from simple to complex. It enables you to handle millions of particles, which run on GPU. Inspired by the leading tools for film visual effects, the VFX Graph is easy to use and empowers artists to create standout VFX for games and more.
The Lightweight Render Pipeline (LWRP) now includes the experimental 2D Renderer, which contains 2D Pixel Perfect and the new Light 2D component. Add lights, blending effects or normal maps to your sprites to enhance the graphics of your 2D games with easy and complete control. Learn more about 2D lighting in this talk from GDC 2019 and in the documentation.
Now with the experimental 2D Renderer in the LWRP, you can use Shader Graph to create Lit and Unlit Sprite Graphs. Create shaders for your 2D sprites to recreate effects like deformations, dissolving animations, holograms, simulating materials and any other shader effect you need for your 2D project. Learn more in the documentation.
In a recent blog post, we introduced the concept of Scriptable Render Pipelines. In short, SRP allows developers to control how Unity renders a frame in C#. We will release two built-in render pipelines with Unity 2018.1: the Lightweight Pipeline and High Definition Render Pipeline. In this article, we’re going to focus on the High […]
