Any example of updating Shadergraph shader's parameter through script?

something like this? getComponentInChildren(Renderer)?.sharedMaterial.setValues("_FadeAmount",1);

you just set the property in threejs, we expose all of them directly.
Your example: myMaterials._FadeAmount = 1

3

so id have to have a reference of just that material?

You can use the sharedMaterials array as well

5

if you know that all those materials have that property/shader

6

this.gameObject.getComponentInChildren(Renderer).sharedMaterial._FadeAmount = 1

7

how can i get “_FadeAmount” to not throw error?

That’s typescript complaining since the base material type you get doesnt have / know your custom properties. So you have 3 options:

  1. chaotic: add @ts-ignore above that line
  2. neutral: access like sharedMaterial["_FadeAmount"]
  3. good: delcare a custom merged type with your properties
declare type MyMaterial = {
    _FadeAmount : number;
} & Material;
