[QUESTION] Does rescale factor also modify the radial attachment point ?

Does rescale factor also modify the radial attachment point so I don't need to modify it or not ?

Yes. However, rescaleFactor is only safe if you do not use a MODEL node on the part.

[Greys]

rescaleFactor impacts only the MODEL node, coordinal fields in PART (such as node_), and transforms used by PartModules. It does not impact NODE nodes. This is problematic because MODEL.scale does not impact anything which does not use a transform such as node_ definitions and old style FX definitions, creating a dynamic where if you use MODEL you need to be very careful with rescaleFactor, and if you use NODE, rescaleFactor Must be 1. Additionally, as of 0.25, NODE definitions Could Not define a part's SrfAttach node, suffice to say that the stock game was simply negligent in this regard. I've not inspected the more recent releases but I see no reason to believe this has been fixed. I have previously made a plugin which corrects this situation, you can find it on KerbalStuff as SrFix, but I am not currently in a situation to update it. I do find it doubtful that it needs to be fixed, a recompile is likely all that is required at worst, and it has a very open license.
