Sakura River is a living 3D scene for your stream. Every message your viewers send drifts under the water, past the bridge and the cherry trees — and chat can call the rain, the night and the fireworks.
It sits behind your gameplay or your avatar like any other background — except that your community lives in it.
Messages under the water
Each message becomes a line of text carried by the current. Messages push apart, turn like leaves and bend with the waves.
Twitch and 7TV emotes
Emotes appear as pictures, animated ones included. Your channel's 7TV set loads by itself.
Viewers as koi
Switch it on and every chatter gets a koi in their name colour that swims closer whenever they write.
Dawn, day, sunset, night
The sky travels through a full day in ten minutes — or stays at the hour you choose.
Chat commands
!sakura, !rain, !wind, !fireworks, !koi, !gong, !night… Viewers shape the scene together, with a shared cooldown.
Lanterns and a ferryman
Add floating lanterns that carry messages, or a boat that chat steers with !left and !right.
Try it
On stream, chat does this
These buttons drive the animation behind this page. It is a light sketch made for the website — the real scene is in the pictures and the trailer.
Viewpoints
Seven places to sit
Change the camera with the arrow keys while you are live. The text on the water turns to face you, and the camera glides from place to place.
For VTubers
A room of your own
A tatami room with shōji screens, a paper lantern and the moon in the doorway — modelled in Blender and ready to stand behind your avatar. The middle of the frame stays free.
Furnished, lantern-only or completely empty
Sunlight falls in by day; the lantern lights the room at night
Above the river or high up in the tower
Seasonal
Halloween mode
One word in the link turns spring into autumn.
Carved pumpkin lanterns on the banks and floating on the water
Maple-red trees and falling leaves instead of petals
A harvest moon, a purple night and bats from dusk till dawn
Viewers' lanterns become pumpkins glowing in their name colour

FAQ
Good to know
Do I have to log in or paste a token?
No. The scene reads chat anonymously. You only type your channel name into the link.
Which emotes work?
Twitch emotes and your channel's 7TV set, animated ones too. BTTV and FrankerFaceZ are not supported.
Will it slow my stream down?
It is a real 3D scene, so it uses the graphics card. On an Apple M5 a frame takes about 16 ms at 1080p; the economy mode roughly halves that. On an older computer start with the economy mode.
Can viewers break something?
No. Commands share a cooldown and only change the weather, the time of day and effects. The camera and all settings are yours alone.
Does it work with YouTube or Kick?
The chat connection is built for Twitch. The page offers a small script interface, so events from other platforms can be fed in with your own script.
Can I change the font and the size of the text?
Yes. Any Google Font or a font installed on your computer, plus letter spacing and size — all through the link.
