Substance Designer 6 Now Available

I found this thread through Google, and I just wanted to add here (although it has nothing to do with Unreal) that when exporting an SBSAR from SD6 and importing it into Unity I experience the Unity version of this exact same error. It is: “Failed to retrieve a single SBSASM file in the archive… Did you use the Substance cooker to generated the archive ?”. This could suggest something changed in the archive format that makes the plugins no longer able to read it?

I have also tried the compatibility modes and so on.
