createTextureForCameras(
    scenePath: string,
    filter: (child: TreeNode) => boolean,
    textureWidth?: number,
    textureHeight?: number,
    scaleFactor?: number,

根据场景地址获取场景，并根据过滤器，获取所有符合条件的相机，渲染为2d贴图并返回单一场景需要用到多个摄像机时可使用此方法被filter过滤掉的Camera组件会将enable设为false
Parameters
- scenePath: string
- filter: (child: TreeNode) => boolean
  判断该树节点的相机组件是否需要作为Texture返回
