This one actually contains baked-in geometry displacement for the ground plane, because Octane doesn't yet have support for micropoly displacement. There's a normal map helping the details on the ground plane too.
Oh, gotcha! Yeah, I really don't like being without micropoly displacement. BI and Cycles don't have it yet either, though I've seen some talk about it. With Blender you can do it like Zbrush (map + multires modifier), but that's just _so_ much less efficient than the displacement I've gotten used to in Poser. It's the one primary (for me) feature that might send me to Lux if I'm not rendering with Firefly. I mean, yeah, there's lots of general aspects, like speed, general quality, etc. that will influence my choice of renderers. And for a long time, GI, caustics, and SSS were the big features I was looking for, so it's amazing that I now have a _huge_ array of choices in terms of free or affordable renderers that can do all of those things. Even Firefly can do 2 out of the 3. So I can't complain. But I do wish micropoly displacement were a little more standard as a feature.
I know what you mean. I think Octane will implement it eventually, as it's definitely a much sought-after requirement for any modern render engine, and if they are to compete with other unbiased CPU engines like Maxwell or Luxrender, then they need to make it a feature. All other 3dsmax render engines support it, like MentalRay and Vray, but I don't like biased engines as much, even though in the right hands, you really wouldn't notice the difference.
