started with unity 2018.1.13, got the errors in console, thought that probably this is a bug of beta, but then tried with 2018.2 and again got the errors, I don’t think nobody noticed it yet, so probably I’m doing something wrong.
STR:
create a new 3D project
in the Package Manager install Render-pipelines.light
Result:
Errors in console: Shader error in ‘LightweightPipeline/Standard (Physically Based)’: failed to open source file: ‘LWRP/ShaderLibrary/InputSurfacePBR.hlsl’ at line 117 (on d3d11)
You created a 3d project so you don’t have the correct renderer assigned for SRP.
Fix
1 - To fix your problem you need to create a render pipeline asset and assign it. You can see how to do that here - Feedback Wanted: Shader Graph page-8#post-3411230
Future Projects/Creating a Project
2 - From what I read it seems like you are creating a new project to use the Lightweight Pipeline. You can just create a project with the Lightweight Pipeline Template and everything will be set up for you.
