Bug描述

[BUG]: LitMaterial.baseMap设置BitmapTextureCube错误：doesn't match the layout's binding dimension

期待的结果

创建一个几何体，设置LitMaterial材质，想要独立设置六个面的纹理

测试引擎版本:

本地运行出错的Orillusion引擎版本, e.g. 0.8.2

代码示例

const obj = new Object3D();
let mr = obj.addComponent(MeshRenderer);
mr.geometry = new BoxGeometry(3, 4.37, 0.02);
let material = new LitMaterial();
let evnMap = new BitmapTextureCube()
let urls: string[] = []
urls.push('https://cdn.orillusion.com/textures/cubemap/skybox_nx.png')
urls.push('https://cdn.orillusion.com/textures/cubemap/skybox_px.png')
urls.push('https://cdn.orillusion.com/textures/cubemap/skybox_py.png')
urls.push('https://cdn.orillusion.com/textures/cubemap/skybox_ny.png')
urls.push('https://cdn.orillusion.com/textures/cubemap/skybox_nz.png')
urls.push('https://cdn.orillusion.com/textures/cubemap/skybox_pz.png')
await evnMap.load(urls)
material.baseMap = evnMap;
mr.material = material

目前LitMaterial还不支持独立设置的这种特性，需要自定义shader来实现~

实现自定义shader的方法能给一下吗
