How can I render a matte (white on black or white on transparent) using Eevee ?
What I ask is a type of render that would render faster than a regular one. I just need the "shapes", not the materials / reflections / colors.
If it exists, I would like to be able to "switch" to the matte render without having to change every material.
Currently, what I do is that I disable all the lamps and objects I don't need, set the world to black color, and set film > alpha > transparent in the render panel. It works but I guess that there might be a better solution.
