How do you think they achieved this?
I learned 3D on Lightwave which, in 2002, was a contender with Maya and 3D Studio Max. Because it was free, I downloaded Blender back then, took it for a spin and was a bit disappointed. Because it was open source and community driven I filed it in my brain alongside Ubuntu Linux as “wait and see”. I had a look recently and have to say, I’m impressed.
