FPSSample can't find levels, new install problems

i'm following the instruction on glithub for FPSSample on unity 2018.3.0b10 (i know the doc say
2018.3 beta 6 but it seems that's not available for download now) and all is good until i load the project tools window

under Levels i only see Bootstrapper but accord to the docs i should be seeing more levels, like dummy, Level_01 etc

so i go directly to the scenes folder and try to click on all available scenes but there is nothing in them

in the console i get this

"
Failed to load 'D:/Unity/FPSSample-master/Assets/ScriptableRenderPipeline/HDRP_Assets/HDRenderPipelineAsset.asset' because it was serialized with a newer version of Unity. (Has a higher SerializedFile version)
UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)
"

i wonder if anyone can point me in the right direction to get this demo working? thanks

PS, i downloaded from glithub with a .zip and unpacked

 

oh, maybe the answer is here https://forum.unity.com/threads/i-can-not-find-the-scene.580333/

i need to clone the project, not download the .zip

 

I bet you are right, that you were able to download a good bit of it via ZIP but need to download the whole thing via LFS Support:

"IMPORTANT: This project uses Git Large Files Support (LFS). Downloading a zip file using the green button on Github will not work. You must clone the project with a version of git that has LFS.
You can download Git LFS here: https://git-lfs.github.com/."

Taken from -> https://github.com/Unity-Technologies/FPSSample

 

Did you launch the sample correctly with the Git LFS ?

 

Yes, it works fine.
