Custom Render Feature script template to be added to a LWRP Renderer. Drag 'n Drop this script to your project, write the desired rendering code. It now it's available to be added to a LWRP renderer by clicking on the + icon under renderer features in the Renderer inspector.

// This method is called before executing the render pass.
// It can be used to configure render targets and their clear state. Also to create temporary render target textures.
// When empty this render pass will render to the active camera render target.
// You should never call CommandBuffer.SetRenderTarget. Instead call <c>ConfigureTarget</c> and <c>ConfigureClear</c>.
// The render pipeline will ensure target setup and clearing happens in an performance manner.
public override void Configure(CommandBuffer cmd, RenderTextureDescriptor cameraTextureDescriptor)

// Here you can implement the rendering logic.
// Use <c>ScriptableRenderContext</c> to issue drawing commands or execute command buffers
// https://docs.unity3d.com/ScriptReference/Rendering.ScriptableRenderContext.html
// You don't have to call ScriptableRenderContext.submit, the render pipeline will call it at specific points in the pipeline.

// Here you can inject one or multiple render passes in the renderer.
// This method is called when setting up the renderer once per-camera.
