Any plan to support new version of VRM?

[is0263rf]

このリポジトリはVRM 0.xに対応していてVRM 1.0には対応していないようです。
VRM 1.0に対応する予定はありますか?

Issueありがとうございます！

VRM 1.0に対応するモチベーションはありますが、現在対応するための時間がなく、対応できていません。
VRM 1.0対応のpull requestは受け付けています。

Thank you for this issue!

I'm motivated to support VRM 1.0, but currently don't have the time to provide the support.
I welcome pull requests for VRM 1.0 support.

ありがとうございます。実装と仕様書を理解してみて、行けそうならPull Requestを送ります。

VRM 1.0 レンダリングは現在主流ですか? そうでない場合、その必要性は何ですか? レンダリングはできず、「分析」することしかできないようですが?

Is Rendering VRM 1.0 a thing now? If not, what is needed? I see that only "parsing" is possible, but not rendering them?

@c4b4d4
VRM 1.0 is becoming mainstream, but VRM 0.x models are still widely used.
To render VRM 1.0, it's necessary to adapt the parsed results to the rendering system of Apple platforms (SceneKit), which will take lots of time to support.
Currently, VRMKit is in the middle of supporting VRM 1.0.

Is the development of this active at the moment? What is the stuff that would take the most time to achieve it?

I'm pretty interested in VRM 1.0 support. Maybe pinpointing what is needed to achieve it, could encourage other people like me and @is0263rf to contribute and make it possible.

Thank you for your interest!

I'm currently busy with my main job, so I haven't been able to start working on this myself. I'm sorry.
The most challenging part is mapping the parsed data to the various classes in SceneKit.

The most important task is to make it possible to create a VRMNode by passing a VRM1 object, as it is currently feasible to load a VRM as a VRMNode. Modifying this part requires changing many affected codes.

VRM refers to VRM 0.x model data, and VRM1 refers to VRM 1.x model data.

Hi, @c4b4d4 . Actually, I have successfully rendered a VRM 1.0 file. But I haven't sent a pull request because my implementation has some shortcomings.

https://github.com/is0263rf/VRMKit/tree/development

For example, I haven't implemented Expression (BlendShape).

I don't know if my implementation will be useful to you. I look forward to your pull request to the tattn's repository.
