The format remains as DDS and the skin templates remain at 2048 x 2048 pixels. So basically nothing has changed.
New models will not be a problem as no skins will have been released yet.
However, if an existing OBD model is updated, then there is a chance that the DEVS would need to revist all skins for that aircraft, in order to re-align certain areas that may have been altered. In that case any skins for that aircraft, created outside of OBD, would also need the same re-alignments.
As yet I don't believe any of the existing aircraft models have been changed externally to any great degree - the team are to busy creating new stuff
