Shader (PBR) does not work

[benmetz]

When trying to compile the op "Shader (PBR)" there's the following error in the tooll console:
"Failed to update operator Shader (PBR)Func. The operator has been disabled.
error CS0103: Der Name 'SetupPbrPointLightsStructuredBufferForEffect' ist im aktuellen Kontext nicht vorhanden.
51 in " SetupPbrPointLightsStructuredBufferForEffect(context, "PointLights", ref _pointLightsBuffer, ref _pointLightsSRV);"
