If you’re a VTuber, you already know your avatar is your brand. Now, with the Blerp VTube Studio Pet integration, your pet can lip-sync in real time to Blerp sounds, TTS, and media alerts. Making every redemption more interactive and way more entertaining.

No extra complicated setup. No weird workarounds. Just seamless lip-sync between Blerp and your VTube Studio pet.

Let’s break it down.

What Is the Blerp VTube Studio Pet Integration?

The Blerp VTube Studio Pet feature allows your connected pet inside VTube Studio to automatically lip-sync whenever:

  • A Blerp sound is redeemed

  • A TTS (text-to-speech) alert plays

  • All Sounds and TTS are triggered

That means your pet reacts in real time to your community’s interactions.

Viewer redeems a chaotic sound? Your pet “says” it.
TTS message comes through? Your pet lip-syncs it.

It’s instant. It’s synced. And it feels alive.

How to Set Up the Blerp VTube Studio Pet

Follow this step-by-step guide to get everything connected:

1. Open VTube Studio

Launch VTS and make sure your pet model is loaded.

2. Enable the Plugin API

Go to Settings → "VTube Studio Plugins" → Turn on "Start API".

3. Update Your Blerp Main Browser Source URL in OBS

Append the following to the end of your Blerp main browser source URL in OBS:

?vts=true

Example result:

https://obs.blerp.com/pwn/yourId?vts=true

You don't need to add a new browser source for this — this is just a modification to your existing main browser source.

4. Approve the Plugin in VTube Studio

Look for a "BlerpVTS" plugin request and click Allow.

5. Refresh the Browser Source if Needed

If you don’t see the plugin request:


  • Go to OBS

  • Open Browser Source properties

  • Click "Refresh cache of current page"

6. Map the Blerp Parameters

In VTube Studio, map the Blerp parameters (listed in the table at the bottom of the setup page) to your main model’s inputs.


If you're using just one pet, only map the parameters that don’t have a _2 or _3 suffix.

7. Fine-Tune Smoothness

Adjust smoothing settings inside VTube Studio to make the lip-sync feel natural and match your pet’s style.
