Creating random colored particles using Dynamic Inputs

In this section, we will see how we can chain Dynamic Inputs to create randomly colored particles.

We’ll continue to use the NewNiagaraSystem particle system. We will also explore a few new UI elements added to the Selection panel that make the process a bit easier.

Let us start by double-clicking on NewNiagaraSystem to open it in the Niagara Editor. First, we need to disable a few modules in our System to prevent conflicts and enable our Dynamic Inputs to work properly. The module that we will disable is the Scale Color module in the Particle Update section. This module would otherwise overwhelm the random colors assigned by our Dynamic Inputs. There is no technical requirement for us to disable the module. We have only done so to make it easier to understand our Dynamic Input.

After disabling the Scale Color module, all the particles will be colored...
