### 3/5 — Am I only allowed to import animation or pose files?

*2025-08-20*

This app looked promising, but I don't know how to import an avatar without importing it as an already animated character. I can't take the animation off even by clicking delete keyframes, and when I press new clip there is no option to add a model shown anywhere.  I can only add one from motion list, but they already have animation. What do I do?

**Developer response:** Thank you very much for your review, and I sincerely apologize for the very late reply.
To add motions, please use the Motion Capture button on the TOP screen.
Additionally, FBX or BVH files can be imported into the app by saving them in the animations folder, or by using the My Assets site:

レビューをくださり誠にありがとうございます。お返事が大変遅くなり申し訳ございません。
TOP画面のモーションキャプチャボタンからモーションを追加していく手順になります。
また、FBXやBVHファイルなどはanimationsフォルダに保存するか、マイアセットサイトを使ってアプリにインポートすることができます。

### 5/5 — Nice

*2025-07-15*

I really like this app, my only problem is that the “perfect sync” doesn’t work for custom characters

**Developer response:** Thank you very much for your review. I sincerely apologize for the very late reply.
In order to use Perfect Sync, the avatar itself needs to be compatible.
Please try converting it with a tool like this:

レビューをくださり誠にありがとうございます。お返事が大変遅くなり申し訳ございません。 
アバターにパーフェクトシンクの対応をする必要があります。こちらの様なツールで変換してお試しいただければと思います。

### 3/5 — Toon filter

*2025-03-28, version 1.10.200*

I can’t seem to find the toon/anime filter, did you remove it? Please bring it back 🙏

### 4/5 — 😍

*2024-03-12*

So I think it’s a good game but at the start I was really struggling with trying to make videos so then I figured it out on camera mode but my body is always twisting around and I don’t like that so that’s why I gave this a four star rating

**Developer response:** Thank you very much for your review.
レビューをくださり誠にありがとうございます。
