I'm using Unity 2021.3 built-in render pipeline and this should work and probably does but sadly some of the scripts rely on outdated UI calls and despite me not wishing to use any of the UI stuff it appears to be hard coded so I can't simply ignore it as it throws errors which disable building. If this gets a update which makes the UI stuff optional then I'll revisit it as I suspect this to be just what I need.

抛开过期代码不谈，Demo场景的被遮挡物体都在闪烁。因为代码中是用的CullingGroup，和随机射线，随机射线你知道是什么概念吗。CullingGroup自带距离剔除和视锥剔除，但是遮挡剔除只有在unity的PVS启用才会生效，这里不烘焙的话这个API就是个摆设，而随机射线就是闪烁的原因

Seems like just a setup issue with tags and layers not setting. Layer and Tag your objects 'IOC', add an extra unused layer 'occludee', in camera set layer mask 'IOC' and 'occludee' to that. Set samples to 2000. And flicker is fixed. Layers are just not set proper on import. Edit : To collide with environment, set environment tag / layer to IOC == this WILL CAUSE LAG... to fix, set iclod mode to static on enviros. Hiding objects set to occlude.

性能不好,开了不如不开

Fantastic starting point to dynamic occlusion! You will have to fix about 5 depreciated variables if you plan on using Unity 2022, but that is to be expected and it works well apart from that.

even after fixing all the errors, the spheres in the Demo scene constantly flicker and don't get culled even when they are clearly hidden from view... maybe it worked in the past now it just doesn't. Should be deprecated.

2016年的版本了，在5.x里应该都无法直接使用

After debugging errors... i have more FPS without this asset.

This asset was created in 2016 and apparently has not been updated since that time. If you are still using the old version of unity, this asset is the perfect choice for you. In all other cases, prepare for errors and learn the scripts to fix them.

此插件在2016年停止更新，经过实测2019版本已无法使用（但你会原理的话可以自己根据代码修改）
