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

i see, if i set “enable GPU instancing” the material breaks

@Marcel_Wiessler1 :cactus: sorry one more thing, is it possible to draw transparent shadergraph on top of worldspace UI?

by user 263967078346653697

43

Yes (if you dont set the canvas to “renderOnTop”)

44

this must be off if you have that component (if not you dont need to do anything)

pretty sweet

I love your camera transitions and splines (?) too

51

it feels very good

52

and in general you built a fun world

Added a new sample for this and also code here: Script Examples | Needle Engine Documentation

import { Behaviour, serializable } from "@needle-tools/engine";
import { Material } from "three";

declare type MyCustomShaderMaterial = Material & {
    _Speed: number;
};

export class IncreaseShaderSpeedOverTime extends Behaviour {

    //@type UnityEngine.Material
    @serializable(Material)
    myMaterial?: MyCustomShaderMaterial;

    update() {
        if (this.myMaterial) {
            this.myMaterial._Speed *= 1 + this.context.time.deltaTime;
            if(this.myMaterial._Speed > 1) this.myMaterial._Speed = .0005;
        }
    }
}

The little wall plane in the back is using that script: https://engine.needle.tools/samples/custom-shaders/
