I have a 3D model, but I don’t really know what to do with it... There’s a collab stream coming up, but if we’re just going to sit side-by-side in OBS, maybe Live2D is enough... But deep down, I really want to express more with 3D... Have you ever felt the same way? Still, doing a collab in VRChat seems like a hassle, and renting a studio—how much would that cost? Don't worry. The 3D collaboration streaming system 'CollabSession' has you covered! Using VMC, it supports facial expressions and full-body tracking—all with just a webcam! You can move freely around a virtual city, making it easy to collab from any location you like! Besides standard cameras, it also supports Spout cameras ! By installing the Spout plugin in OBS, you can capture high-quality video without showing the UI to your viewers! Supports up to 8 participants! Even with a large group, everyone can hang out in the same city! You can view the operation manual by clicking 'View the Manual' at the bottom right of the Steam store page. ━━ About Webcam Tracking ━━ ※Tracking uses a webcam that has been pre-configured on Windows. If a capture card or a video device that does not show your upper body is set, tracking will not function properly. ※Linking a Pixiv account is required to use this software. ※If you want to use your own avatar, you need to register your model on VroidHub. Some fully custom VRM models are not supported when using webcam-based tracking. This follows the naming conventions of VRM models created with Vroid Studio. Meshes corresponding to the face should be named 'face', 'head', 'body', or '顔'. The Blendshape for closing the left eye must include 'eye' in its name and end with 'L' or 'l'. The Blendshape for closing the right eye must include 'eye' in its name and end with 'R' or 'r'. The Blendshape for opening the mouth must end with 'mth_a'. ※Screenshots 1-4 depict character models which are not included with the base game.   These models are downloaded from 3rd party websites.
