The top half of the image looks really good. :) Keep working!

Thanks Oscar. You are right.
Another attempt.
The terrain becomes from houdini inside C4D. Sadly I can not spread instances objects over the mesh linked to houdini and I need to export the mesh :roll:. The multifractal function from houdini is very versatile.
A patch of 5x5 km with 32 mill. of poligons and over 100000 trees So, hard to work...

The general test for a landscape.
Probably I start a new thread called "landscapes" for the next one in a weeks.

Hi

Congratulations on the excellent scene!

A question; I understand it's been used Houdini for the mountains but for vegetation perhaps Surface Spread?
The choice of using Houdini + Indigo instead of the known modeling software landscape has its own reason?
You have a very powerful computer to handle the millions of polygons of the scene?

Thank you very much. Really apreciated the feedback.
Contegufo, I use houdini for the landscapes because is at the moment the one that allows me to extend the space. I try large landscapes since the beginning and the multifractal asset that I found in a course of CMIVFX is very powerfull for this purposes. For the vegetation I´m using Surface Spread, yes.

Now, please Ono, teach me how to use the internal scatter of indigo or I can´t go further. The scene reaches an amount of ram in C4d that don´t allow me to export a large number of instances. It´s not a question of time because run out of memory. I feel that with the scatter of indigo I can go over two millions of instances (enough for now).
So please, post a simple scene with some teapots in a plane or something...

10x10 km. Not enough grass ...

It would be a very nice animation bird's but perhaps the calculation is very heavy?

Hi contegufo, flock of birds for more over... (maybe). It´s planed and now with the connection of C4D and houdini is easier to do.

OK. I got the code of the scatter installing sketchup and doing an exportation.
The first test goes more or less good (there are a lot of different plants but I see only the big patch). More than 6 millions of instances in 25 seconds and two minutes of installation. Very good!

Then I try to take the last scene and things go odd. :lol:

Some sketchup user can help me with the scatter numbers? I try with some values and I get 0 instances or this :) .
Thank you in advanced. And sorry for the personal request Ono ...

Here is an example showing mixing of two different scattered objects, with different weights so that one is more likely than the other.

You do know Ono made some significant scattering optimisations for version 4 right? :)

So many thanks for the example Ono. Now multiple objects works and I can go to near 20 millions of instances. This is so good for landscape attempts... But a last question, I can´t find a meaning of slope in the scatter. Is it possible in any way?
Thanks for the info Oscar, I have no idea about the optimisations. I will change to v4 soon. :)

P.D.: near twice of speed in v4.
There is a "material" option for the scatter, but it don´t works if you select a material that is part of a blended one. It would be great that this work for a subcomponent material (because the meaning of slope is given by the material). Only an observation :) .

Hi,

Sorry for the late, but I had a problem with my internet during a long time, the cable suffered corrosion and had to be replaced...

First, great renders man!

I had made a few tests to get the god rays through the clouds but I failed on each situations.
I tried with more or less fog, I tried with different altituds for the clouds, I tried with both materials the one without haze and the one with the haze, and I tried with extra atmospheric and a real life sized sphere with an SSS to simulate the atmosphere.

I guess my render is in the subject of the post since it is a country landscape, and actually a real one not very far from my home, that I tried to recreate. It's still a work in progress though. A lot of objects scattered here and I use sketchup; I've got other scattering tests from sketchup if you would like yonosoy..
