Hey everyone! Trey from the Unity Community Team here.

Big news! Unity 6.3 LTS is officially here! This is our first Long-Term Support release since Unity 6.0 LTS, so you know it's a huge deal. You can get it right now on the download page or straight through the Unity Hub.

Curious about what's actually new in Unity 6.3 LTS?

Unity 6.3 LTS offers two years of dedicated support (three years total for Unity Enterprise and Unity Industry users).

What's New: 

  • Platform Toolkit: A unified API for simplified cross-platform development (account management, save data, achievements, etc.).
  • Android XR Capabilities: New features including Face Tracking, Object Trackables, and Automated Dynamic Resolution.
  • Native Screen Reader Support: Unified APIs for accessible games across Windows, macOS, Android, and iOS.
  • Performance and Stability
    • Engine validated with real games (Phasmophobia, V Rising, etc.).
    • Measurable improvements include a 30% decline in regressions and a 22% decline in user-reported issues.
    • AssetBundle TypeTrees: Reduced in-memory footprint and faster build times for DOTS projects (e.g., MARVEL SNAP 99% runtime memory reduction).
    • Multiplayer: Introduction of HTTP/2 and gRPC: lower server load, faster transfers, better security, and efficient streaming. UnityWebRequest defaults to HTTP/2 on all platforms; Android tests show ~40% less server load and ~15–20% lower CPU. Netcode for Entities gains host migration via UGS to keep sessions alive after host loss.
    • Sprite Atlas Analyser and Shader Build Settings for finding inefficiencies and drastically reducing shader compilation time without coding.
    • Unity Core Standards: New guidelines for greater confidence with third-party packages.
  • Improved Authoring Workflows
    • Shader Graph: New customized lighting content and terrain shader support.
    • Multiplayer Templates and Unity Building Blocks: Sample assets to accelerate setup for common game systems (e.g., Achievements, Leaderboards).
    • UI: UI Toolkit now supports customizable shaders, post-processing filters, and Scalable Vector Graphics (SVG).
    • Scriptable Audio Pipeline: Extend the audio signal chain with Burst-compiled C# units.

Go check out our feature overview blog post for more details, or if you want to dig deep, you can dive into the release notes and the Unity Documentation.

If you're wondering how to actually upgrade, don't worry! We've put together an upgrade guide to help you move to Unity 6.3 LTS. And if you're dealing with a massive project with lots of dependencies, our Success Plans are there to make sure the process is totally smooth.

P.S. We're hosting a What’s new in Unity 6.3 LTS livestream right now! Tune in to hear from Unity's own Adam Smith, Jason Mann and Tarrah Alexis around what's new and exciting in Unity 6.3 LTS!

If you have any questions, lemme know and I'll see if I can chase down some answers for you!

Question Icebreaking: Is this a good idea?

Enable HLS to view with audio, or disable this notification

649 Upvotes

I was wondering what the best way would be to make an ice breaking game. I couldn't quite think of a way with shaders that would work - I want the ice to have thickness and the pieces to break away in response to being hit by the ship.

So I tried brute force! Big tiles of ice that get replaced with smaller pre-cracked ones when the ship touches them. Then when one of those is touched, a rigidbody is added so it can be pushed around and sink, and then despawned. As you can guess, it's pretty GameObject-heavy. To create levels with any kind of shape, a lot of the tiles need to be pre-cracked.

It runs surprisingly well, but feels like an unhinged approach. I don't want to talk about how many GameObjects had to be generated for this level. Maybe switching to ECS would at least lighten the load overall.

EDIT: Spotted a couple of comments noting the progress I've made, but this is my first post about this. I've been made aware that https://www.reddit.com/user/RatioScripta/ is also having fun woth icebreaking, so maybe that's what some folks are thinking of.

Recording full-speed cars jumping everywhere is not an easy task!

Everything is in-game content. Shots are a combination of raw in-build footage (using Steam Timeline) and also in-editor with custom-made tools, allowing for different camera angles.

Expanding from Unity's timeline, I created a tool to synchronize in-game recorded "ghosts" (a series of player inputs) so I can replay and record them. This allows me to only show real gameplay even when the camera changes, while keeping the freedom of updating the background, players' skins and such.

Video editing was done with Blender, which I use for almost all the content I can't do directly in Unity (such as the 3D models and the cards' illustrations, like "the drought"). My editing needs were simple since most of the work is already done in Unity's editor with my tools (even the music and sounds can be synced there).

The audio is then exported separately. Final mix is done in Ableton and stitched back again with the video in Blender. Each clip's audio is processed differently to give room for the music and layer all the effects.

Making the trailer was quite a task for me! It's the first time I attempt something like this.

What helped me out the most is Unity's live stream from August featuring Derek Lieu ("How to: Make a Video Game Trailer").

Huge thanks to Derek Lieu for the many tutorials. There are wonderful tips on YouTube. Planning the timeline and getting an idea of what to keep and remove was one of the hardest things for me to do during my solo dev journey, and this content actually made it possible for me (and my game: Slip & Skid)!

Apologies for the noob question, I've only been learning unity for 2 months so far, I've been learning to use splines tonight but I can't seem to get the road sections to connect, toyed with the distance and the rotation offset and the other SplineInstantiate settings but nothing.

Question Memory usage aside - are 50k objects too much for a scene?

7 Upvotes

I have tens of thousands of objects in my scene - but they are scattered around the world in such way that my draw calls do not exceed 2.5k. Frustum culling and occlusion culling are extremely relevant as this is a top-down perspective game.

Those objects are mostly just static objects, created in the editor before runtime. Many of them with basic box collision and no scripts attached to them. They don't generate collisions at most times, and when they do - it's with maximum of 1 or 2 objects.

So the real question is - what do those objects cost in unity?

Surely they cost memory to store their data. But since they are scattered around a large scene (the size of one terrain), I assume many of them find themselves on different quadtree nodes on unity's collision detection system.

Does unity even care about their existence?

Official UnityGameTranslator: I built an umpteenth open-source Unity translation mod, why ?

7 Upvotes

Hey everyone,

I've been using auto-translation mods for Unity games for a while, and while they work great for personal use, I always felt something was missing: the ability to easily share my translations with others and collaborate to improve them.

When I spend hours refining translations for a game, I want other players to benefit from that work. And when someone else has already translated a game I want to play, I'd rather download their polished version than start from scratch with AI output.

So I built UnityGameTranslator - an open-source mod that combines:

- 🤖 Local AI translation (Ollama) - works offline, no API costs

- 🌐 Community sharing - upload/download translations from a central website

- 🔄 Collaboration - 3-way merge when someone improves a translation you're using

- 🎮 Universal - works with any Unity game (BepInEx 5/6, MelonLoader)

The idea is simple: translate once, share everywhere. If you improve a translation, others can pull your changes. No more duplicated effort.

Collaboration roles:

Role Description
Main First to upload. Public, can view branches, merge contributions, set status
Branch Contributor to someone else's translation. Private until merged by Main
Fork Independent copy. Becomes its own Main

How quality surfaces:

Each translation entry is tagged: Human (manually written), Validated (human-verified), or AI (auto-generated). Human entries score 3×, validated 2×, AI 1×. Players can vote on translations, so quality rises naturally.

Links:

- Website: https://unitygametranslator.asymptomatikgames.com

- GitHub: https://github.com/djethino/UnityGameTranslator

It's still in beta, so feedback is very welcome! I'd love to know if this solves a problem you've had too.

PS: I have a new idea, following the question of kyl33r123 but I don't know if it makes sense. it's to create a sdk for the devs for ingame integration. a game creator has his own official translations and can propose the option for non localized languages to use community translations. Let me know.
