If I open a model made with skp 2013 and an earlier version of UV toolkit(and TT_lib) and try to edit the UV-mapping in Skp 2015 with the most recent UV-toolkit and TT lib , will the UV-mapping get messed up?

I know this thread is kinda old, but I Just came across this and it really made my day. Exactly what I was looking for! Saved me from some long a** hours of line drawing! Thanks a lot

Hi, I'm using UV toolkit with FredoScale for game modelling.
I've noticed that when I export the model(to dae), I get one texture for each quad face. I'm making a city model and this results in thousands of textures... Is this just how the plugin works or is it something I can do about it?
Edit: Never mind, Just found out that the faces has to be triangels...
