Recommendations to others considering RenderMan:
Like a lot of render engines, each one is slightly better at certain aspects and end up catering to certain products. Renderman has been around for decades, but has been used mostly in-house by Pixar for rendering top quality stylized feature animations. It performs beautifully and achieves pretty realistic results but overall will have a cartoonish, vibrant look to it. Getting absolutely photo-real is sometimes a miss -if you're going for something more sterile, architectural it's not the best use, since the render output leans toward renders with vibrancy, contrast, and a slightly plastic-y simplified finish on surfaces. However it is a very good render engine especially for its price. Review collected by and hosted on G2.com.
What problems is RenderMan solving and how is that benefiting you?
We are able to look develop a lot faster, use directional lights with falloff which helps fake better lighting in big outdoor/outerspace scenes. Renderman has fewer complex controls in the Render Settings and faster IPR which allows you to see the final color results even while its still resolving the resolution which beats VRay's older versions which would make you wait until it was 100% finished to know what the colors/values actually looked like.
As a junior employee, its faster for me to try something with Renderman now, and not worry to much about increasing resolution parameters and complex technical settings in the Render Settings. Its also easier to get in the ball park in terms of the speed and simplicity of the render. Review collected by and hosted on G2.com.
