Whispers of anticipation for Volumetrics have been heard amongst the Blender community for a while now.
It’s exciting, because it allows you to create stuff like smoke, fire, fog, haze or basically any material that fills the air.
And as of a couple of months ago, it was finally added to Cycles :)
In this Blender lighting tutorial you’ll learn the basics of it, and how to use it to create a popular effect: Hazy Atmospheric Lighting, aka the “God ray“.
The tutorial covers the atmospheric lighting only but you can use it to create your own scene like the one above.
1. Go to the World settings and under Volume option, select Volume Scatter.
2. Adjust the Density value.
3. Enable Homogeneous Volume.
4. Reduce render fireflies by adjusting the Clamp values under Render > Sampling.
1. Adjust the depth of the Cube and position the Camera as seen below.
2. Create holes on the elongated Cube.
1. Select the Spot Lamp and adjust the Node settings as shown, to imitate a sun lamp (which is currently not supported).
2. Adjust the Light Paths Volume Bounces and set the World Density to 0.2.
3. Create a light ‘gobo’ (shadow) by adding holes to Plane and positioning it infront of the Spot Lamp.
Finished! Now you know the basics you can start making hazy light schemes like this:Close Summary
