Galacean Engine 1.5 is now officially released 🎉!

This update delivers several major features:

AIGC: AI image-to-model capabilities are now available, enabling one-stop generation of 3D models for more efficient creation.
Mini Game: The platform now supports subpackages, completely removing package size limitations and making resource management more flexible.
Rendering Upgrades: Added FXAA anti-aliasing and color management optimizations, resulting in more refined color and image quality.
Particle System Enhancements: Supports external forces and mesh emitters, providing greater freedom and variety in effects creation.
Project Collaboration: Invite collaborators via email or share links to facilitate efficient teamwork and co-creation.

AI Image-to-3D Model

Newly introduced image-to-model capabilities eliminate the cost of searching for or creating 3D models, allowing you to rapidly produce projects or demos. We plan to continue adding new AI capabilities to unlock more possibilities—stay tuned!

Mini Game Platform

Added support for subpackaging in WeChat Mini Games, allowing resources to be divided into a main package (essential resources) and subpackages (on-demand loading). In the new Mini Game export panel, you simply add subpackages and link them to folders; resources not part of a subpackage fall under the main package.

We also replaced the built-in WeChat Mini Game build with the Galacean build system, unifying the construction process for all mini-game platforms and addressing compatibility issues in the old solution’s third-party packages.

Rendering System

New FXAA Anti-Aliasing

We introduced Fast Approximate Anti-Aliasing (FXAA), which smooths edges by detecting pixel contrast in the final rendered image. Unlike MSAA, which only addresses aliasing along object edges, FXAA can reduce aliasing on every pixel in the image, including specular highlights and alphaCutoff edges generated by shaders.

Color Management Upgrades

We’ve enhanced the overall color space by supporting hardware-level sRGB textures, converting material, lighting, and particle color inputs to linear space, as well as supporting linear transparency blending and HDR color editing. These improvements boost overall color accuracy and performance while reducing shader code complexity.

Material Drag-and-Drop Interaction

You can now directly drag materials onto entities in the scene, making it easier and faster to replace materials on a renderer component.

Particle System

The particle system adds a ForceOverLifetime feature to simulate external forces like gravity or wind acting on particles.

Particles now support Mesh Emitters, enabling particles to be emitted based on mesh vertices—often used for effects that interact with a model’s surface.

Project Collaboration

We’ve introduced a highly anticipated project collaboration feature. You can find the “Invite” option in the editor sidebar, which allows you to invite others to join your project via email or shareable link, making team co-creation seamless.

Other Improvements and Optimizations

Multi-language: Improved Chinese-English bilingual documentation and added Japanese support.
Editor View: Added mouse-hover entity selection for a smoother editing experience.
Project Settings: Manage project information, members, and snapshots directly on the project list page.
Camera: Introduced the isAlphaOutputRequired interface for maintaining canvas transparency and blending with the browser.
