After I’ve updated to HDRP 7.3.1 (Unity 2019.3.13f1), almost all materials on scene are gray. And, I cannot fix this error. I’ve searched the web for a fix, but… nothing. so?
Library\PackageCache\com.unity.render-pipelines.high-definition@7.3.1\Runtime\RenderPipeline\HDRenderPipeline.LookDev.cs(6,45): error CS0535: ‘HDRenderPipeline’ does not implement interface member ‘IDataProvider.Cleanup(StageRuntimeInterface)’
