VTube Studio

4️⃣【 For Live2D Riggers 】

You can use the new Live2D Cubism 5.3 Editor when creating your models, but you cannot use the new model features (new blend modes, off-screen rendering, ...)

When exporting, make sure you select "SDK 5.0/Cubism 5.0", otherwise VTS will not be able to load your models.

Again, as soon as I can realistically estimate a timeline for this, I will let you know on all VTube Studio social media. At the moment, the best ETA I can confidently give you is "sometime this year".

Thank you for your patience.

Careful coordination and validation are necessary to make sure 5.3 support can be implemented properly, even if that means it takes more time. I am working closely with Live2D Inc. to ensure that the final implementation will be able to support all features that users of VTube Studio rely on.

That implementation was ultimately scrapped in December, which led to Live2D's decision to switch to a new URP-based rendering approach in order to restore missing functionality.

After a while, it became clear that their initial implementation could not correctly render models, broke existing functionality and could not realistically be fixed.

3️⃣【 Additional Context 】

Since the first early beta versions of the 5.3 Unity SDK last year, I have been in continuous contact with Live2D Inc. and provided technical feedback.

• After the upcoming February release for VTube Studio and assuming the Live2D 5.3 Unity SDK is nearing completion, implementing 5.3 support will be my sole focus. Because of the scope of changes, I will rely heavily on community testing.

• However, these features will be implemented differently under the new system, which will require substantial rework on the VTS side.

• After discussions with Live2D Inc., I was given assurances that all functionality VTS depends on (including Live2D items and in-between-layer items) will be supported in the new system.

• In addition, VTS itself will have to be migrated to Unity's URP, which is a major project on its own. Many existing systems are incompatible with URP and must be rewritten from scratch, including the VFX system and other core components. This is currently in progress but will take more time.

• Once the new SDK is finalized, large parts of VTube Studio will need to be re-implemented to restore full functionality.

2️⃣【 Next Steps 】

• I have made it clear to Live2D Inc. that complete and correct 5.3 support is of the highest importance to VTube Studio's users. They have acknowledged this and agreed to prioritize it accordingly.

• Until Live2D Inc. release a stable, fully functional SDK, I cannot integrate it into VTS.

• The new 5.3 Unity SDK uses an entirely new rendering system and switches from Unity's built-in render pipeline to Unity URP. This makes it fundamentally incompatible with how the old SDK works.

• At this point, I have not been provided with a timeline for when the Live2D 5.3 Unity SDK will be finished. As long as that remains unclear, I cannot give an estimate for 5.3 support in VTube Studio.

1️⃣【 Background: Status of the SDK 】

• While the Cubism 5.3 Editor has been released, the Live2D Unity SDK for 5.3 currently only exists as an early beta. It is not feature-complete, tested, or suitable for production use.

【📢 Notice regarding Live2D Cubism 5.3 】

VTube Studio may support Live2D Cubism 5.3 later this year, but the required Unity SDK from Live2D Inc. has not been released yet.

【📢】 If you're using the new split Live2D item feature and the items are cutting into your model, remember:

You can insert the front and back part of the item anywhere into your main model. Just find the correct layer and it'll look great! 💖

(thanks @nepheleVT for the clip)

Added one more item by @7MC_Official ✨ This one didn't quite make it in time for the initial release, but it's ready for you now!! ☀️🍹 Set up an expression to customize the color 🌈

Update VTS and you'll find it in the item menu as "Swimming Tube" 🏖️

Yippii 💖 Thank you for the kind words!!

It should be fixed now, in version 1.32.3 ✨ Might take a few minutes for Steam to show the update.

Thanks for reporting! This apparently happens when the other model has the same ArtMesh ID as the one the item scene attaches the item to.

There's gonna be a small update tomorrow that fixes this and a few other issues.

Yeah, you nailed it LMAO!!

And finally, thanks to ああああ-san (x.com/q07a_ ) for composing the wonderful song you can hear in the trailer!! I'm really happy I got to work with one of my favorite artists!! ✨✨✨
