WebGL2 Breaking Custom Shader

by the way, @titansoftime as someone who worked a lot with SPE, I can guarantee that you will like particular way better. It has more functionality and runs faster. For example, you can express color and size evolution with arbitrary curves. You have soft particles out of the box, various blending modes, frustum culling (both simulation and rendering), automatic texture atlas for all your particles and a bunch of other stuff.

It’s part of meep, specifically this section:

Usnul/meep/blob/95617f2bd3dd526e7c40e416fff3060bf401e40e/src/model/graphics/particles/particular/engine/ParticularEngine.js

import { ShaderManager } from "./ShaderManager.js";
import { BinaryNode } from "../../../../core/bvh2/BinaryNode.js";
import List from "../../../../core/collection/List.js";
import { ParticleEmitterFlag } from "./emitter/ParticleEmitterFlag.js";


function ParticularEngine(assetManager) {
    this.shaderManager = new ShaderManager(assetManager);

    /**
     *
     * @type {THREE.Texture|null}
     */
    this.depthTexture = null;

    /**
     *
     * @type {THREE.Camera|null}
     */
    this.camera = null;

I was greatly inspired by SPE when writing that engine, since I was migrating from SPE at the time.
