There is a way to convert shader graph to shader code.
You can open the graph, right click the master node and select "Copy shader".
Paste the shader code to your shader file.
Example: Vertex Color Shader
Shader "Unlit Master" { Properties { } SubShader { Tags{ "RenderPipeline" = "LightweightPipeline"} Tags { "RenderPipeline"="HDRenderPipeline" "RenderType"="Opaque" "Queue"="Geometry" } Pass { Name "StandardUnlit" Tags{"LightMode" = "LightweightForward"} // Material options generated by graph Blend One Zero Cull Back ZTest LEqual ZWrite On HLSLPROGRAM // Required to compile gles 2.0 with standard srp library #pragma prefer_hlslcc gles #pragma exclude_renderers d3d11_9x #pragma target 2.0 // ------------------------------------- // Lightweight Pipeline keywords #pragma shader_feature _SAMPLE_GI // ------------------------------------- // Unity defined keywords #pragma multi_compile_fog //-------------------------------------- // GPU Instancing #pragma multi_compile_instancing #pragma vertex vert #pragma fragment frag // Defines generated by graph // Lighting include is needed because of GI #include "LWRP/ShaderLibrary/Core.hlsl" #include "LWRP/ShaderLibrary/Lighting.hlsl" #include "CoreRP/ShaderLibrary/Color.hlsl" #include "LWRP/ShaderLibrary/InputSurfaceUnlit.hlsl" #include "ShaderGraphLibrary/Functions.hlsl" struct VertexDescriptionInputs { float3 ObjectSpacePosition;
