Title says it all I guess.  My notes from years ago don't say much.  'Dart.  Tut.  World Creator.  Import grayscale.'

Carrara can use grayscale to make 100m to 1000m ground plane, or was that Bryce?   

PS: Not seeing any topics other than an announcement & Wendy's sharing an animation.  "Browse archives" doesn't seem to do anything.  Normal or got wiped when forum was closed?

Thanks.  Lot of content to scroll through.   Bound to be something.  ; )

Not aware of any tutorials on the subject, but.....

Yes, Carrara can use Grayscale images to create terrains.  Start with an empty scene, then drag in a Terrain object via the tool icons or front the Insert Menu drop-down.

That will get you into the terrain editor, from where you have lots of options in creating a terrain using the tools in the editor.  If you're not comfortable with the painting tools of the editor the you can Clear the canvas using the 'Clear' button and 'Import'  a height map  or displacement map available from numerous sources on the Web to generate a terrain, real world or otherwise.  First thing I would do though, is READ the MANUAL.  I know the documentation sucks, but even the Carrara 6 Manual that comes with Carrara 8 has a wealth of info that will help

Hmmm...  Feels like an empty tavern.  Where is everyone?  I guess they've moved to social media, or...  More about that later.

Anyway, after plowing dozens of different ways to phrase search terms, Google did have the link I remembered.   Many thanks to "Dartenbeck."
