I have Affinity photo latest v of 1.8 and DxO labs / nik collection 3.0
What are the proper steps / How do i create a smart object using Nik filter in Photoshop Elements so i can re-edit the Nik Fillter in Affinity Photo? I assume the smart object has to be created in a photoshop like app.
What I've done so far 
- Opened a raw file in Elements 2019
- Applied a Nik filter (say Analog - Camera 4)
- Saved the file as a PSD file
- Dragged (not open) the psd file to the affinity photo software - blank page 
- I selected the layer, then Affinity filter - Nik - Analog
- The Nik app opens for further editing but the the settings are not the same as the Camera 4 (or any filter preset) but is close. I can re-apply stuff and/or perform further edits
- But it is not the same as double clicking the nik filter layer and re-edit the exact same preset settings w/in the Nik filter tool the 1st time around; Doing a Nik filter in Affinity photo and re-selecting for edit does similar behavior
- The goal is to re-edit the exact same nik filter settings again (e.g., i want to make some subtle changes based on the print) 
- Since Affinity Photo 1.8 supports smart objects and since all of the Nik webinars show doubling clicking the Photoshop Nik filter as a smart object to make changes to the existing applied Nik filter, there has to be a way to do similar (re-edit the same Nik Filter settings) in Affinity Photo .. whether i have to use a photoshop tool ish (elements) or something else to get this to work
