I decided to try this out. Copied the SAS Part file, changed some names, checked the log: (Filename: C:/BuildAgent/work/812c4f5049264fad/Runtime/ExportGenerated/StandalonePlayer/UnityEngineDebug.cpp Line: 43) Warning: Variable rotPower not found in SASModule Module! (Filename: C:/BuildAgent/work/812c4f5049264fad/Runtime/ExportGenerated/StandalonePlayer/UnityEngineDebug.cpp Line: 43) Warning: Variable linPower not found in SASModule Module! It looks like those variables are not attributes added to the ship as a whole, rather they are handled by the part's module and SAS doesn't do that. The resulting part worked like a SAS, but didn't have any additional characteristics. Nice probe design, BTW. I love it!!
