Title: Best way to distribute grass on a custom terrain
Post by: jorgensen on May 24, 2012, 08:06:16 pm
Hi

I wonder which method would be the best for distributing grass objects over a large imported terrain?

Or is there a other way to make a terrain looking overgrown?

Thanks :-)

If you use Lumion vegetation you need to place batches by hand and randomize them afterwards. this works.

Also if you want to use your own grass models you can use some scatter plugin and automate. I use Forest pack Pro for such things for example.

I'm still waiting for paintable vegetation system in Lumion. :D

seems like an immense pile of work :-(

I use revit as modelprogram - and I don't think that adding plants inside Revit is the best solution.

I really hope that Lumion, in some time, will support custom terrain the same way as Lumion terrain :-/

You could render a heightmap of your terrainmesh, then import that as terrain into lumion
and drape your own mesh over it. This way adding grass is a tiny bit easier.
Figuring out the best settings for rendering a good heightmap for Lumion should only take
you approx. halve the week so most def. a lot faster!
Hey, how am I doing in the assistance department?  ::) :-[

If you hold down Ctrl and place an object it will place 10 copies of the object in random rotations.  So if you use a large patch of grass it will place 10 of those.  It should be able to cover your terrain pretty quick.

It only works on Lumion terrain :-(

Actually it works on imported terrains as well - the only problem is that randomizing the inserted instances will not work on imported terrains (it will drop everything down to the Lumion terrain).

Heightmaps may be a solution IF you do not need very accurately built terrain AND IF you do not want to have some extensive structures over them like roads or streams running in accurately modelled valleys etc.

Tested CRTL + Left mouse. It won't work on my custom terrain, only the first object, the rest is placed on the Lumion terrain  |:(

Ah, already then! Too bad.

Yes, this is also my biggest wish in Lumion (although the custom terrain material and saving / re-applying my custom materials had been competing with it until the latest update).

It would be interesting as a short term stop gap maybe if the Lumion terrain could be manipulated to conform to the shape of your imported model terrain. Then maybe you could drop your imported terrain out and just use the Lumion. Maybe that's a bit crazy though.

That's weird because it worked on my terrain just fine.  I created it in Sketchup and imported as .dae.

Ctrl-placing foliage on custom terrain has never worked.
It places 1 item correctly, the rest is placed on the Lumion terrain.
So, good for perfectly flat terrain, useless for anything else.

funny, I could SWEAR that I had already ctrl placed foliage over a custom terrain without any trouble. Maybe a false memory then...

I had exactly the same. Had to check it with Morten to make sure  :-D

Not crazy at all. At least from a user's point of view (not from the programmer's). Something like the "stamp tool" we are using in SketchUp. It's somewhere buried in the wish list section when I was contemplating on these things, too.
