Funnel is a Syphon server plugin for Unity. It allows Unity to share rendered frames with other applications that supports the Syphon protocol (e.g., MadMapper, VDMX) without introducing any performance loss.

This version is redesigned and optimized for the new OpenGL backend (OpenGL Core) and not compatible with the legacy OpenGL backend. If it's required to support legacy OpenGL, use the legacy version instead.

• Mac OS X 10.8 or later
• Unity 5.3 or later

This version only supports the 64-bit runtime and the OpenGL Core API mode. The legacy version is available for legacy setups.

• Download and import the plugin package.
• Add the Funnel script to a camera that's to be shared.

That's all! It automatically sets up a Syphon server and starts publishing rendered frames towards Syphon client applications.

The name of the Syphon server is set in the following manner:

[Process Name]-[Game Object Name]

It's useful to identify the server on the client side.

Screen Width/Height, Anti Aliasing - Configures the screen to be sent.

Discard Alpha - Clears the alpha channel with 1.0 (completely opaque) before sending.

Render Mode - Determines how the frame is shared.

• Send Only - Sends the frame and doesn't keep it. The rendered frame is only available on the client side.
• Render To Target - Sends the frame and copies it to the render texture.
• Preview On Game View - Sends the frame and display it on the Game view.
