How to Add Effects to Your Live Stream

This guide is for desktop creators who want a LiveGen character, outfit, or scene effect in an OBS broadcast. LiveGen creates the visual result; OBS composes and broadcasts the scene. A working effect preview is only the first check: your audience sees the captured OBS output, including any delay, controls, or interruptions that remain in it.

Choose an effect for the segment

Start in LiveGen Explore, where the current tools include:

• ✓Become a Character: use Live Morph for a character-based look.
• ✓Outfit Try-On: open Outfit Swap for a clothing transformation.
• ✓Style Your Whole Scene: open Style Morph to restyle you and your surroundings.

Choose one look and check it with the movement you plan to make on stream. These are generated effects: do not assume perfect face consistency, precise clothing fit, or unchanged background details. Treat each mode as a separate setup unless the current interface explicitly supports the combination you want. For a character-focused setup, see the VTuber guide.

Set up LiveGen before opening the broadcast

Capture the running window in OBS

Browser Source does not capture your existing Chrome or Safari tab. OBS describes it as an embedded browser that loads its own URL. Pasting a LiveGen URL there is not the same as capturing the signed-in session and effect already running in your normal browser. Use the window-based workflow below for that session. See the OBS Browser Source documentation.

Windows

In the OBS Sources panel, add Window Capture and select the browser window running LiveGen. Confirm that the selected window contains the moving result. OBS documents Window Capture as capturing a particular window and its contents; see its Window Capture guide.

macOS

On macOS 13 or later, add macOS Screen Capture, choose the window capture method, and select the LiveGen browser window. Grant OBS the screen-recording permission requested by macOS. OBS also documents this source for macOS 12.3–12.6, with different audio support; older setups need the capture source supported by their version. See macOS Screen Capture.

Frame the output and check audio

Crop and resize the captured window until the intended result fills your scene. Inspect the OBS preview for browser chrome, account details, controls, or an untransformed camera view. Keep the LiveGen result visible in its dedicated window while testing.

Configure your microphone in OBS and verify its meter and recorded sound separately. Seeing a moving browser window does not prove your voice is being captured. Listen to a local recording for silence, echo, and voice-to-picture delay before choosing the final audio setup.

Run a pre-stream check

Troubleshooting

• ✓OBS shows the wrong page or a sign-in screen: confirm you selected the existing LiveGen window. A Browser Source loads another page instead of capturing that window.
• ✓The captured output is blank or frozen: first check whether LiveGen itself is updating. If it is, reselect the window and check capture permissions; if it is not, inspect the app's connection, camera, and session messages.
• ✓The effect breaks up or changes unexpectedly: simplify the scene, improve lighting, and test slower movement. If it remains unsuitable, use the fallback instead of promising viewers a stable effect.
• ✓There is no voice, echo, or a timing mismatch: inspect the OBS audio sources and replay a local recording. Adjust the setup against what you actually hear and see.
• ✓You need a different effect mid-stream: make that transition off the live scene and recheck the crop before returning.
