sorry face for the misunderstanding, we are talking of the same thing :)
anyway instances are perfect for grass and the hair module is already ready for instancing export.

@ Mayan:
you are completely right about the bad maxon policy for pricing and modules suddivision :(

Probably I will sometimes anyway use Blender because of e.g. trees, people and cars. I dont think that trees from 3Dwarehouse (Sketchup) would look great in Octane. I have some good free and some bought libraries that I will try to get to Octane. Maybe only via Sketchup import/export (it would be nice), but probably via Blender (import SU scene to Blender, add trees, maybe grass and export to Octane)...
But something like hair/grass shader would be nice and most fast in Octane, useful also for rugs, carpets..

Can anybody tell if grass created in Blender via particles/hair (I am very new to Blender) can be rendered in Octane? I hope that instancing will work also.

What trees and bushes and bunches of grass do you guys use in your archviz renders and what is your pipeline? Do you go via Blender or some other app? There are so many so BEAUTIFUL images of villas with plants in Octane gallery and the most seems to be 3D, no postwork! I really wonder.

Here is the nvidia standalone hair test software.. if it's open source like nvidia is nowdays, there should be a way to program it into something else - it's realtime like playing a game, so I guess this particular code isn't 100% integrateable into octane.. but looks there is a way in .. this is about a year old technology

http://downloads.guru3d.com/NVIDIA-Hair ... -2541.html




I guess, the hair module could possibly work like a shader, using the area of the material and normals as the base of the hair growth.. and have various modes of placing it.. maybe by using a noise shader to distrubute hairs on the area, or distribute by polygons or vertex. Have some basic settings like length, width, curly whatever..
But I don't see how the instancing part would work. Or how would you "brush" the hair, maybe something like a fur plugin in c4d works at simple settings..

Well the technology is here in some way.. now when the programmers at nvidia manage to develope an open source code for the real time renderers such as octane, then everyone will have it :)
That is all brand new technology and everytime someone makes a new code it's a sort of a small revolution going on in there. The early starters often become the mainstream on the market.. like 3d max was and is now, started over 20 years ago and now it's the most popular piece of software. And we hope to get everything developed in a couple of weeks/months time. We need some Nikola Teslas in the programming world..?

Nice find, also includes source code and instructions on making other hair styles and sims.

Wow, this is wonderful. Thanks. I hope that there will once be this kind of shader in Octane. As far as I know, no other unbiased render (Maxwell, Indigo, Luxrender, Arion) have hair/fur/grass shader. Many of us have to find workaround via other sw and i/o, ram etc. issues and Octane could have big advantage with this shader.
