I had a big kick off about this here with lots of testing/examples which were easy to set up. If you can, please vote for it on the issue tracker here
** Also how can I nondestructively use this edited shader in a project with URP? I tried overwriting the original with it in Package Cache folder and it gets overwritten by the editor always. If I put it in another folder it just errors out and says that it can’t access Speedtree7Passes.hlsl.
