Quote - Unbias render engines are slow if you want to generate realistic animations particularly if it involves complex scattering like SSS. The examples I've seen  for Octane were fast but  had used simplier materials (don't know what version was used). I've seen a few interesting videos on Keyshot but they have all involved environmental lighting so possibly its optimised for that. The other thing you need to consider is how will you get the animation into the Render engine, if its from Poser you'll need to use an existing plugin or be a good programmer as manual importing obj and assigning materials takes a long time.

Octane is different than most other unbiased render engines in that it comes with more than one render kernel (algorithm).  You can use Octane in Path Tracing mode, which is basically the same as Luxrender, only much much faster.  However, you can also use it in a slightly biased, Direct Lighting/Diffuse mode, which is more like Brute Force GI in biased render engines like Vray.  The quality is still astoundingly good, but render times can be dramatically improved over Path Tracing, for very complex shader structures like SSS for skin.  So, depending on the kernel you use in Octane, SSS may or may not present a significant hit to render time, like it can in other unbiased engines.  That's a big plus in regard to flexibility, and quality vs time considerations.
