Warning: Viveza 3 is NOT backwardly compatible with Viveza 2 when applied to Photoshop Smart Objects. When opened, a Viveza 2 Smart Object layer, the layer inactive and cannot be edited. I suspect that Silver Efex Pro is similarly affected.
I think the new NIK collection would contain sufficient legacy code to at least open Viveza 2 layers and read the various settings to convert to the new version. I’m rolling back to maintain editability until NIK fixes this.
