MultiPass is a simple Editor Utility Widget that uses the Movie Render Queue subsystem to render and queue up different types of passes for compositing externally to give more control over your renders.

In addition to the standard types of passes achievable in the stock Movie Render Queue, MultiPass allows for configurations that include Per-Light, Light Groups, Emissive, Fog and Pseudo Shadows (both combined and split per light or light group).

This allows for greater flexibility when compositing your shots and if you are familiar with tradition Visual Effects pipelines this falls much more in line with that.

There are a few things to note, This does increase render times to a degree as it runs a render for each of the new passes, it isn't double the time per pass because we aren't rendering all the lights at once when using the per light or light group passes.

Requires Movie Render Queue and Movie Render Queue Additional Passes Plugins to be Enabled!

Additional note, if you cancel a render while its running please open Movie Render Queue and ensure the queue is empty before running another render, as otherwise this will error out.
