Custom Cast

📖 What is Custom Cast?

A character-creation app that lets you build an original 3D avatar using just your smartphone. Fine-tune face, hairstyle, body type, and outfit, and on supported devices you can move the avatar in real time with face recognition. You can stream directly to Niconico Live, and Premium members (¥550/month) can export in VRM format for use in apps like VirtualCast. Available on iOS and Android.

💡 When to Use It

Use this when you want to try streaming with a 3D avatar built entirely on your smartphone, before investing in a PC or expensive equipment. It's well-suited to beginners who want to start chatting or planned streams on Niconico Live without showing their face, and on supported devices you can even animate expressions with face tracking. Using the official channel's VRM export, you can expand into connected apps like VirtualCast via THE SEED ONLINE — handy if you'd rather create your character on your phone first and grow your activities from there.
