StreamBridge is a live synchronization tool that connects Blender and 3ds Max directly to a running Unity scene, helping artists avoid repeated exports, imports, and material fixes during development. Its plugins support Blender 4.2 and later, 3ds Max 2023 and later, and Unity 6, including URP, HDRP, and Built-in Render Pipeline projects.

Through a persistent TCP connection, StreamBridge sends changes as users work. It supports meshes, including vertices, normals, UVs, colors, and submesh layouts; skinned meshes, weights, skeletons, and bone transforms; vertex-color painting; scene hierarchy, transforms, and visibility; and material-slot routing by name. Objects can also be added, deleted, or renamed, with corresponding GameObjects reflected in Unity.

Users start the server in Unity, connect from their DCC application, and choose responsive or interval-based performance syncing. Synced objects serve as live previews, while final assets can still be exported normally. StreamBridge is offered for a one-time price of $57, with future updates included and support available through Discord.
