In my travels people have asked many times about linear workflow in visual effects. I wrote a pdf describing the foundations of linear workflow and why it’s important for the rendering process. Feel free to contact me with questions and if needed, I will update the document.

I wrote a primer about how to use V-Ray for Maya. This is for new V-Ray users and I think it helps set the stage a little for how the renderer works and how to work with it.
