Upgrading Unity versions, I noticed that taking the absolute of the Normal Vector produced different results. It's likely that this is causing my shader look different than before. I'm not proficient enough in writing shaders to solve this so I resorted to a workaround where I export the shader result from 2018.3 and use it in 2019.2. Obviously this is not a very maintainable workaround so in the meanwhile I would like to understand how I can get Shader Graph to export the same result once again. Thanks!
