studios like to use stable(not constantly being modified) or proprietary softwares

back in highschool i started with an autocad program that was "highend" for the time but was still only 2d, i was using it to design mechanical parts for heavy construction equipment. while in college a friend showed me a fledgling opensource program that was so unstable that it was pittifull but i stuck with it, that was the original beta for blender

i started playing with it and it because normal, not long later i got my hands on pixars software and stared playing with that as well

it seemed like every week or so a new for blender hit the web while everything else was only touched once a year or so

i messed with bryce until daz got their hands on it and ive tried poser, silo, mudbox, carrera, hexagon, sculptris, argile, and alot more and keep going back to blender but just like i do most people learn one software and never leave it
