Quote - Question for Paolo. If I stay with 4.37 do I need to update to 2.5 and if I do will it affect anyting in 4.37?  I guess it prolly would not but figure ask to be on the safe side..

That would be 4.0.3.47, aka 4.0. If you do you cannot upgrade to 2.5. DAZ's SDK for Studio is not backward or forward compatible. This means that plugins made for 4.0.3.47 don't work in 4.5 and plugins made for 4.5 don't work in 4.0.3.47. 

Reality 2.5 is only for Studio 4.5 and the reason for it is only to support 4.5, there are no new features. More precisely, there is new support for the .duf format but that is specific of Studio 4.5.

Hope this helps.

Paolo
