AutoLOD - Impostors is only supported by the standard and the universal render pipelines. Baking on HDRP is NOT supported at the moment. If you want to use the tool on HDRP you will have to bake impostors using an URP project and the use the HDRP Toolkit

What is an impostor?
An impostor is a billboard whose material displays a picture of a 3D object. Depending of the view angle, a different picture of the object will be displayed, to fake a 3D effect.
When should I use it?
Impostors are mainly used to optimize an existing scene, to render static objects far in the distance.
You can also use them to get a unique art style with a 3D "snapping" effect.
Can any object in my scene be replaced by an impostor?
Technically, any object with a mesh renderer attached. But you should only replace static meshes far in the distance. At closer range, you will notice the difference as a simple quad doesn't intersect the same way than the original mesh with surrounding objects. Also, impostors are baked in orthographic view, meaning the perspective will be wrong at close range.
Are impostors compatible with the LODGroup component?
Yes. And you don't have to mess with geometry alignment, the tool has an option to set the LODs for you.
How long does it takes to bake an impostor?
Depending on your hardware and the baking settings, it may take up to 30 seconds.
Can I build on any platform?
The impostors shader derive directly from Unity default lit shader, so you should be able to build on any platform.
Is any dependency needed?
No. It is a standalone package.
Asset demo scene uses Ultimate Stylized Nature Pack under CC0 License; see Third-Party Notices.txt file in package for details.
只有标准和通用渲染管道支持 AutoLOD - Impostors。目前还不支持在 HDRP 上进行烘焙。如果您想在 HDRP 上使用该工具，则必须使用 URP 项目和 HDRP 工具包来制作冒牌货。

什么是冒牌货？
冒牌货是一种广告牌，其材料显示的是三维物体的图片。根据视角的不同，会显示不同的物体图片，以伪造 3D 效果。
何时使用？
冒牌货主要用于优化现有场景，渲染远处的静态物体。
您也可以使用它来获得独特的艺术风格，并获得 3D 的 "抢拍 "效果。
场景中的任何物体都可以被冒牌货替代吗？
从技术上讲，任何带有网格渲染器的物体都可以。但您只能替换远处的静态网格。在较近的距离，你会发现不同之处，因为简单的四边形与原始网格和周围物体的交集方式不同。此外，冒名顶替是在正交视图中生成的，这意味着在近距离时透视会出错。
冒名顶替是否与 LODGroup 组件兼容？
兼容。你不必再纠结几何体对齐的问题，该工具有一个为你设置 LOD 的选项。
制作一个冒牌货需要多长时间？
取决于您的硬件和烘焙设置，最长可能需要 30 秒。
我可以在任何平台上制作吗？
