blender is free for a reason. there is no support, they can break compatibility, drop a feature, not document stuff, translate or resolve major bug, basically they can do as they like, there is zero safety there to lean onto if you are a professional. whenever you see fast development, rest assured that is rushed, poorly tested and code is likely not refactored and optimized. Last time I tried it I failed to miss what the hype is, it was terrible. from my pov on C4D, Maya and Houdini are complete 3D packages. hate AD for what they did to xsi so no Maya, Houdini is too techy td tool with long turnaorund times, and C4D snapped right away
