That IS the big question, wether or not they have manpower to actually upgrade the software beyond making them running 100% stable on AOS4.x (and other Amiga related platforms).
Doesnt it run already?
Would actually be intresting to hear a general comment about what plans they have with the different programs/utilities.
I am sure they wish to develop it further. But it is quite large package and developing such beast is more like full time job. Then it would not hurt if you had some interest to modelling and rendering and have knowledge about other similar packages what they can do.
It is tough.
Reason why development of these software packages was stopped... not enough demand, not enough users, not enough money. H&P claim they sold 15000 AmigaOS copies in late 90s. Now try to relate that figure to this day, 15 years later and you see it has not get better in that regard. User base is smaller than it was when this software was maintained.
