Fader allows you to lerp between values and colors for a given duration and toggle lerp direction.

Specific implementations can e. g. fade Materials, Enviro Time, VFX Spawn Rate, etc in and out in Unity.

• Material Property
  • Fade Float and Color Properties of Materials
• Material Object
  • Fade two material using Unity's internal Material.Lerp function
• VFX
  • Fade VFX property values
• Enviro
  • Fade Enviro's time in and out. This requires the scripting define symbol ENVIRO to be defined
• Aura 2
  • Fade the Aura 2 Camera and Fade the Aura 2 Volume

In my case I was toying around with the new Malbers Realistic Wolf. The eyes use the Standard material, property _EmissionColor as color. The fur is a special shader with a property _EmissionPower as float.

Looks like this then:

This video clip shows how it looks with both the Material Property and Enviro Fader applied:

If you need a custom fader, I suggest to check out VFXFader.cs or EnviroTimeFader.cs. The implementation should be straightforward.
