Thank you Jimmy. The info regarding 18.104.22.168 is what i was looking for. Whenever an upgrade like this happens i don’t know how to find out about it and have to resort to the forums to find out. Also because i dont have much a memory, i dont remember how to upgrade me existing version, so if you could tell me how i would be grateful. Always assuming that it is sensible to or possible to upgrade to a beta version?
As for the question of prime, i knew about saving as scenes, but that seemed too simple. I am curious about file types myself, for example obj. files and so on, is there some information i can read about these and how to work with them. This may well be beyond my brain power, but who knows?
Thank you again
