Demo project?（demo 项目）

无。

补充

我这边定位到源码，暂时先通过修改引擎代码，重新构建，来规避这个问题了。

getHash () {
        return this._manualHash || (this._effect && this._effect.getHash());
},

修改后：

getHash () {
        if (this._manualHash) {
            return this._manualHash
        }
        if (this._effect && this._effect.getHash && typeof this._effect.getHash === 'function'){
            return this._effect.getHash()
        }
},

从报错信息看，应该是材质被destroy掉了，可能是资源被错误释放了，具体需要给个demo才能排查。
