8.1 Clothing on 8

I'm sure this has been covered SOMEWHERE but doing a search got me hundreds of pages of unrelated information so I'm hoping someone here quickly knows an answer... Why doesn't clothing made for 8.1 work on 8? Why isn't Genesis 8 an option in autofit when trying to use 8.1 clothing on 8? How do I get it to fit correctly? And why are so many products for 8.1 not labelled as such and therefore not wanting to work on 8?
Comments
No adjustment is needed, just cancel the AutoFit and it should work. The auto-conversion of (many) assets like materials was added when 8.1 was released, since at that point most things would have been for 8, but they didn't implement the reverse (as is fairly typical). You can edit the Scene Identification of the base figure to avoid the AutoFit dialogue, but then it won't warn you when aplying 8.1 things like materials or shapes that may well not work at all (if they use the 8.1 UVs or shapes).
Aww [goodness]! Thank you! I wish I had known this hours and hours of rendering ago!
Another way to solve the situation is to edit the metadata to Genesis 8 (Female or Male depending on the gender for which the clothes were made) to the allowed Compatibility.
I don't know if there is side effect and it'll not make products based on geoshell work on the incorrect figure, due to surfaces changes between G8 and G8.1
