HDRP Shader Graph - generate shader code from Graph - ArgumentNullException

In ShaderGraph 3.0.0 (HDRP 3.0.0) and U2018.2.0f2, when I right-click Unit Master node and select "Generate Code" I get the following error:

ArgumentNullException: Argument cannot be null.
Parameter name: source
System.Linq.Check.SourceAndPredicate (System.Object source, System.Object predicate)

Did you ever get an answer for this? I've got the same issue in LW-SRP as well. It seems not so much whether it's LW or HD, but the Shader Graph itself..

 

Same here. Could you solve it?

 

Right-click, select Copy Shader and paste into a text editor.

 

Hi,

We have fixes for this in PR that we are currently trying to get into the main branch. Until then please follow @sstrong 's advice and use "Copy Shader" to copy the full shader to clipboard.

Thanks for your patience.
