Taking my custom Mazda MX5 I created, I wanted to dive deeper into lighting. For this project I setup Blender so that it exports all of the lights as separate passes. Doing this would allow me to composite them all together in photoshop.
Below you can see a GIF of my layer build up. I used a colour overlay on each light to control the lighting. I plan to do similar for most of my future projects as it gives me a much larger creative freedom post render.
