I'm using Blender 2.80. I have a scene, where I fire 20 cannons at the same time, with smoke and fire. How can I render (with Eevee render) some cannons separatley?
This tutorial explains how to work with view/render layers https://www.youtube.com/watch?v=jOO3K1B9vgg
View layers is to render separately. render layers is how you combine them in compositing.
