Creating the particle material

The next thing on the list is creating the particle material. In real life right when sparks are emitted from a fire, they are in a very bright white color. As they rise and cool off, they turn to more of an orange red-ish color. We can create this same look by adding a couple of different nodes in the material as follows:

1. Select Icosphere and open Shader Editor once again. Then, create a new material by clicking the New button.
2. Delete Principled BSDF and replace it with Emission Shader, then set Strength to a value of 20.
3. Plug Emission Shader into Surface in Material Output.
4. Next, we are going to add a new node called Particle Info. To add this new node, press Shift + A, go to Input, and select Particle Info.

Particle Info node

This node allows us to take certain data from the particle system and have it influence the material. For example, you could take the Random output and plug that into ColorRamp. Now each particle...
