If i upgrade to 4.5, it sounds like i’ll have to load all my scenes in and resave them in the new format?
Probably. But it shouldn’t be a problem to go one by one, as you need to.
[quote author=“BlitzMan” date=“1353899074"That will be interestng with 60+ scenes to resave. I assume my saved material presets will still work ok right?
They should. I didn’t notice anything that changed that would affect the materials.
[quote author=“BlitzMan” date=“1353899074"I’ve got a considerable amount of scenes built up using 4.x. Does the 4.5 upgrade auto un-install 4.x?
It’s supposed to, but depending on system configuration, version Windows and so on…it may not.
