It makes a difference if I use a DLL with extern functionality (no matter what) and if I use a dll which permits to use some acknex internals. But anyway if we can use it, it doesn't matter that much. I just wanted to write my opinion and say that it would be a bad move if acknex plugins which extend its funcionality would be restricted to use just for the ones who purchase a higher Edition. But if it is still possible to use them ( DLLs compiled with A* SDK) then just forget my words spent here
I just doubt that in future anyone who is able to real propgram with C++ etc., will spend his money before testing at all what is possible for him on the developing level, which goes further the normal use of this engine. I think it's nice for new user to see that this software is extendable and then they spend the money for higher version nearly automaticaly. It's the "welcome" factor which I wish more...
