unity cubemap怎么生成

Use Assets->Create->Cubemap, set its properties, and drag six Texture assets onto corresponding Cubemap "faces". Note that the textures must be re-applied if changed because the textures are baked into the Cubemap Asset and are in no way linked to the textures.
用资源>创建 - > 立方图（Assets->Create->Cubemap），设置其属性，并拖6个纹理资源到相应立方图的"面"。注意纹理如果改变了，必须重新指派，因为纹理烘焙成立方图资源就与纹理没有关系了。
Use the Texture Import Settings to create a Cubemap from a single imported texture asset.
使用纹理导入设置（Texture Import Settings）从一个单独导入的纹理资源创建立方图。
Render your scene into a cubemap from script. Code example in Camera.RenderToCubemap page contains a script for rendering cubemaps straight from the editor.
用脚本把你的场景渲染成立方图（cubemap）。 Camera.RenderToCubemap页包含直接从编辑器渲染立方图的脚本代码示例。
