Keyshot?

Does it render hairs, micro and nano meshes, zbrush noramlRGB material, framer materials? Noice as a displacement?

How speedy and convenient it is comparing it with Octane or Redshift ?

Does it work in orto projection?

It renders geometry if those features are converted to mesh, or normal maps where applicable. It handles “medium high” (single digit millions) polycounts pretty well. It can do approximations of most of the ZB default materials, but as it’s an entirely different engine, they’re not a one hundred percent match. Frankly, in most cases they’re better because unlike ZB matcaps in which the lighting is baked in and static, they become real shaders in KS that react to lighting.

Actual rendering speed is only one aspect to how quick and easy something is to use. No CPU based renderer will match a GPU based render in terms of sheer rendering speed. However, it doesn’t matter if you have the fastest renderer in the world if it takes forever to set up to get quality output with. Keyshot is a reasonably timely renderer, with great ease of use, accessibility, and set up time for the quality of results you get. It’s an experimentation-friendly program.

There is a downloadable demo on the Luxion site. It doesn’t feature any of the Zbrush interactivity, but it should answer many of your questions without relying on anyone else’s opinion.

Thanks for the info

I’m an octane user myself (using a titan black and a gtx 680 in tandem). With those cards Octane is faster - at least when the direct light kernel is used. That being said Keyshot is doing quite well and delivers good hard-edge renders out-of-the-box. I have yet to try out how it handles specularity and SSS and all that good stuff, but i’ll say that it is good value for money - even if you’re not going to make your final render from it.
