Blender's volumetrics are great for smoke, mist, fire, and other atmospheric effects. The Volume attribute of your Material Output nodes lets you customize these cloudy things with the node editor. Let's start by seeing how the Volume attribute works with a Principled Volume shader by constructing a smoke ring, and then use a Mantaflow fluid simulation to create realistic burning flames. The finished smoke simulation and materials can be found in ch16_smoke.blend.Let's dive into it:
- Create a new scene, and choose the Shading workspace. Give the Default Cube a new material called Sphere.
- Add a Principled Volume shader with Ctrl + A | Add | Shader, and attach it to the Material Output's Volume attribute. Like the Principled BSDF ...
