this.m_RendererCamera.targetTexture = this.m_RendererTexture;
let texture = this.m_RendererTexture.getImpl();
let material:any = this.m_Model.getComponent(cc.MeshRenderer).sharedMaterials[0];
material.effect.setProperty(‘texture’, texture );
在调用setProperty的时候报错，getImpl不是函数？这个工程在2.13时还没问题， 2.20后就报错了
effect.js:119 Uncaught TypeError: value.getImpl is not a function

帖子的标题应该怎么填啊，填了几十个字还是需要更详细，要疯了啊。。
