grass question

[ewong]

Hi,

I've been playing around with TG4 a bit more recently; but have only with the default scene and
figuring out what each setting does.  Haven't really done much in terms of understanding things
(I seriously hope someone writes a book on this, coz, as I think I've mentioned awhile back,
TG has certainly a steep learning curve).

I've tried to figure out how to create a landscape pic (using the default scene + some changes),
and while I remember it's something to do with displacement and setting max and min altitudes,
I can't remember which shader used it.  So I went and tried adding a grass population, but
can't figure out where I added it (since I can't find the clump in the render of the attached scene).
I'm guessing it's out of the camera view.

What exactly is the right way of creating a grassy-mountainous landscape?

Thanks

Right click on the 3d preview window and click "Select object or shader". Then from the list choose "Grass clump 01".
Then u will see where is your grass.

The grass needs to be population, not a single object, as you did. But it's best to use on relatively smooth country. And populate it close to and in front of the camera! Or the population will be too huge and your populating takes forever.

OR just use Dune's Parkwood grass.

I can't seem to be able to move that grass and have it touch the surface of the terrain.  Moving the
coordinate origin in 3D is confusing.

I finally discovered 'drop to terrain'.  Though I'm confused with the result since it looks more like a small
green lake than a clump of grass.

Well, you also have a lake in there 
If you want to see the grass, you have to populate. Once done, you see all the clumps appear. There is something weird about it though, the strange stripes. And I think it's because your population is way off 0/0/0. Usually it's best to locate any terrain you want to make near or one the central location. Or you will get into trouble with trees slanting and such.
