I have been using smart objects for my Nik edits since about 2009 or '10 in pretty much every instance of using a Nik filter - it seemed like the correct way to go and was fully supported by Nik, Google, and DxO up to Nik 3, and of course was consistent with the non-destructive editing workflow in Adobe. In fairness, I did not install the trial first, so it was competely my fault for not doing my due diligence - but who knew I had to: to my knowledge, DxO did not warn anyone about this omission. I purchased and upgraded to Nik 4 only to find out later that it did not honour Ps Smart Objects created for Nik 3 or earlier (for SEP2 and Viveza 2 only in Nik 4).
