I really want to try shader graph in Unity 2018 but I can’t get it working.

Unity 2018.4.3 LTS, Shader Graph 4.10

I created a graph in project file viewer by click Create->Shader->Unlit Graph, then after rename it, and I tried double click, it throws null object reference exception, and an empty window is opened.

[Exception] Exception thrown while invoking [OnOpenAssetAttribute] method 'UnityEditor.ShaderGraph.ShaderGraphImporterEditor:OnOpenAsset (int,int)' : NullReferenceException: Object reference not set to an instance of an object

I noticed that shader graph has not been updated since a few months ago.

I need help.

Shader Graph was considered ‘preview’ (essentially alpha/beta) for 2018 versions and isn’t going to be maintained any further on that version, unfortunately. The maintained versions of the package are 2019 and above.

OK, but can you tell me which version of shadergraph is usable in Unity 2018 LTS?

alright, forget it, I purchased Amplify Shader Editor, I’m happy so far.
