How Warudo + StreamTranslate works together

Warudo is the most popular 3D VTuber engine for Twitch and YouTube streamers, with native support for Screen assets that can render arbitrary browser content as in-scene 3D objects. This makes Warudo unique among VTuber tools — most others require you to output through OBS first.

To add StreamTranslate, create a new Screen asset in Warudo, set Content Type to Browser, paste your StreamTranslate overlay URL, and position the screen in your 3D scene. The overlay renders as a flat plane in the scene that follows your camera angle.

VTubers with international audiences (especially Japanese and Korean VTubers reaching English-speaking fans, or English VTubers building Spanish/Portuguese followings) benefit massively from real-time translation since chat-based viewers can finally understand spoken content.

Setup steps

In Warudo, go to Assets → Add → Screen. Set Content Type to Browser. Paste your StreamTranslate overlay URL into the URL field. Position the screen plane in your scene where you want subtitles visible. Save and go live.

Frequently asked questions

Does StreamTranslate work with VTube Studio or only Warudo?
VTube Studio doesn't have a native browser source feature — you'd need to output VTS through OBS and add StreamTranslate as a browser source in OBS instead. Warudo is unique in having direct browser asset support.
Can the subtitle 3D plane occlude my avatar?
Yes — Warudo Screen assets respect 3D depth ordering, so you can position the subtitle plane in front of or behind your avatar. Most VTubers position it as a lower-third in front of the avatar.
Does it work with multilingual VTuber collabs?
Yes — each VTuber can run their own StreamTranslate instance with their own mic. For shared streams, dual-language (Pro/Unlimited) shows two languages simultaneously.
