2. Creating and displacing the ground mesh
Open modeler. Create a box object with the following settings:
Triple. Rename surface to Ground01. Check "double sized". Save
I usually number my objects, surfaces and whatever with serial
numbers 01, 02, etc. in order to have intermediate versions,
each being a bit closer to finishing. When i get back to the
scene later, it's easy to remember which one is i.e.. the finished
object. If i have different versions at the same stage i name
them 06a, 06b etc.
Open Layout. Import the Ground object. In the objects tab go
to displacement map.
U se automatic sizing, no pixel blending or tiling (To avoid
artifacts) and Y-axis. Amplitude setting of 3 seems quite ok
for our 30X30 m. ground, giving three meters of elevation where
there's white in our image.
I used .jpg in this case as i (Lazy ;-) use the same images
in this page. A grayscale .iff is better in actual work, saving
memory in LW and lacking compression artifacts.
In objects tab, save transformed as Ground02.lwo.
go back to the modeler for a while to finish our object.
