Can we export this grass and carpet as real 3d objects into Artlantis, or it works only in Cinerender.

AFAIK Cinerender was optimized so that you could keep working on your construction documents or doing design development while it was rendering the views. If I understood correctly at a minimum AC will leave 1 core for the OS, will use 1 for itself so you can keep working, another for PBC-section/elev generation and the rest for rendering.

A standard material library, tuned for CineRender, comes with AC 18.
Not to sound negative, but in the past, I would not describe the materials to be tuned for Lightworks or Archicad.
Your increasing my expectations and hopes. Looking forward to it.
The grass thing sounds cool. Does it only do common grass or can it be manipulated to look like similar forms of ground cover?

As Eduardo pointed out, it is a procedural shader thing... generated by the rendering engine itself, so cannot be seen in OpenGL, nor saved as an object, etc.

Renders happen in the background, so you can keep working in AC as they happen.
See attached for AC 18 with a CineRender running on my 8 core Mac. In the shot, CineRender is using about 6.6 cores and AC is using about 0.5 cores, leaving about 1 core for the OS and other stuff at the moment the screenshot was taken.
Responsiveness - mostly due to Mac OS X - is very good. While rendering, Mail checked for new messages and downloaded them, and CineRender utilization temporarily dropped to 550%, giving more processing power for Mail to finish its job, then returned to 665%. Switching to the 2D window and working, I'm not aware of anything slowing me down.
And, my Mac is 6 years old!

Maybe 3dsmax has set for itself the highest priority (I didn't check) but for me it's fine, it means that it is finishing faster the rendering and have to wait *only* 3 hours instead of 4

Procedural grass... probably using displacement? Displacement is usually CPU and memory hungry and increases a lot the rendering time... i'm curious how does it look and how fast does it render...

Background rendering is huge for architects... you can continue working on details, layouts, other parts of the building, whatever, while a render generates. When you say "when I finish the model and only after it's finished, I'm ...rendering"... well, that's how rendering specialists work... it's not how (most) architects work. It's fine if the background feature is of no use to you... doesn't hurt you in any way to have it.

Renders happen in the background, so you can keep working in AC as they happen.
Open your task manager and under Tasks, for the specific program, Right-click, and then select 'Set affinity' to turn off a particular core (or more) for a program, if you don't want it to use 100% of all your cores leaving your computer unusable.
Of course it will render slower (in the case of rendering), but as soon as you're done doing whatever else you're doing, you can set the affinity of the rendering program back to 100%.

But not setting the affinity was the idea. I was saying that if the rendering engine isn't using all the CPU cores at 100% then it means that probably it isn't using the computer at its maximum and this leading to longer rendering times.
@Karl Ottenstein, i think every architect has his own workflow. For example, at the time I do the sections,details, etc. there's no point of making renderings as the client already knows how the building looks. I'm using renderings only in the early stages of a project. What if the client doesn't like how the building is looking in my renderings and wants me to change, i don 't know, something, and I have finished all the sections, details, etc, even my structural engineer has finished his part of work?

But this is my scenario, probably everyone has his own and it's better to have a new feature rather than not having it.
