In RenderMan, it has the ability to render your scenes faster and manages to get the job done when it comes to animating, motions, may be the most popular renderer than the other renderers, and much more True or False
Renderman was once the most powerful renderer - developed by Pixar - but it was so expensive to buy and so technical to use fully that it never became “the most popular renderer”.
It was used mainly for Film and Feature Animation by larger studios.
No, Renderman is still not the most popular renderer, even though the price is much lower now.
As for speed, it depends on what you are rendering. Why don’t you try Renderman yourself?
RenderMan is fast, and can handle extremely heavy scenes. These two factors made it the leading tool for high-end projects for a long time. However, it’s very fussy to set up; it takes a lot of time and know-how to get even a basic scene looking good. Newer render engines get similar power into a more user-friendly package, so many studios are moving away from RenderMan.
