While working on my last art project, I've developed an open source pipeline for baking lighting in Unity with Octane, with the help of Jason Gendreau.
The tool helps automate the following steps:
-Assigning a bake ID to each object
-Creating the bake camera with a matching bake ID
-Naming the bake camera in a logical manner
-Baking the camera image
-Creating a material for the bake image
-Assigning the image to the material
-Assigning the material to the original object
It also contains a Shell materials that allows you to switch between the original and baked materials in case you need to rebake your scene.
Please give it a try and give us some feedback!
