DepthOfField error using 5.4

Getting the following error

Assets/Standard Assets/Effects/ImageEffects/Scripts/DepthOfField.cs(94,74): error CS0117: UnityEngine.ComputeBufferType' does not contain a definition for IndirectArguments’

have not done anything (as far as I know) related to DOF, but was tinkering with the terrain, any ideas?

It’s also possible (at least it was for me) that you are opening a 5.4 project in 5.3.5. Go back to 5.4 and it works fine (again, at least it did for me).

yet another thing that was fixed by closing and then re-opening Unity. All’s well that ends well.
