👽 Bitsy the Alien 4.5 – VTuber Model Showcase & Creator Diary

Artist made of cuddles and stardust.

Hi, I’m Bitsy—the alien behind iiiSekai Production Studios—and today I’m thrilled to introduce you to my latest creation: Bitsy 4.5, my most advanced VTuber model yet!

This update marks a huge leap forward in vtuber upgrades for both art and rigging. I designed, drew, and rigged everything myself—from antenna to tail. 🛠️✨ Bitsy 4.5 features full Perfect Sync support using Apples 3D face tracking AKRit, giving you crisp, expressive facial tracking that’s perfect for high-level performances or just vibing on stream. I even tackled 2D hand tracking in Live2D for the first time… which, let me tell you, made me cry.

But in the end? Totally worth it.

What’s New in Bitsy 4.5?

• Perfect Sync face tracking – Smooth, responsive, and deeply expressive peepers and smoocher.
• 90° head turn – This was my second try, and it’s already a big improvement. Still perfecting it, but I’m proud of how far I have come!
• Hip XYZ angles – Better balance, more dynamic movement!
• Reactive physics – My favorite part of this model. The bounce and flow feel so alive.
• New sitting pose – Super cute and cozy. Nailed it!
• Attempted conditional physics for tail speed – Okay, I failed this one… but it’s all part of learning. 🌀

This version of vtuber upgrades for my model is the most detailed and technically advanced model I’ve made so far. I’m genuinely proud of how far I’ve come as a Live2D artist—and even more excited to keep leveling up. Every tear, glitch, and keyform was worth it!

What’s Next for Bitsy the Alien?

I’m not done yet! Next up, I’m learning Blender to make a 3D chibi Bitsy model. Expect space buns, soft shaders, and cozy vibes. I’ll be sharing the process, wins, and fails—so follow along if you love seeing how the space magic is made.

Thanks for observing, earthlings.
