'UnityMeshSimplifier' could not be found in unity 6

[mohammadrezahamedi]

Hello,
I get this error, even though I have installed both the addressable and the simplifier packages
please guide what to do
Assets\HLODSystem-master\com.unity.hlod\Editor\Simplifier\UnityMeshSimplifier.cs(25,46): error CS0400: The type or namespace name 'UnityMeshSimplifier' could not be found in the global namespace (are you missing an assembly reference?)

I use this link to install the simplifier
https://github.com/Whinarn/UnityMeshSimplifier.git

@mohammadrezahamedi you need to clone the repository through the git client. just downloading a zip from the browser won't work, as it probably doesn't download everything. Clone using the client's git and then add it to unity according to the instructions and everything will work.

You can't clone the HLOD repository, it will give you errors since there's no manifest file. We have to manually copy both HLOD system and HLOD Adressables folders otherwise it wont work. But after copying the files, you have the UnityMeshSimplifier' could not be found error. Even by adding https://github.com/Whinarn/UnityMeshSimplifier.git, you get the same error.
