Making
Snow in WorldBuilder - Introduction
In
this tutorial, we will create a snowy landscape. We will use Material
Property tools to create snow on the ground, and we will edit
the characteristics of the Compound Sky. We’ll also
utilize WorldBuilder’s Rain/Snow tool to create the
falling snowflakes.
NOTE:
The tutorial is designed to be used with the downloadable demo version
of WorldBuilder 4. Some features such as scene and rendered image
saving are disabled in this version. An example scene file is available
for download.
| Let's
get started. Open
Worldbuilder and the default scene. Several necessary elements
of our scene are already loaded, including a Landscape mesh
object.
|
|
In
order to view the entire scene, let’s ‘zoom
out’ our view. Select Landscape0 in the Scene
Tree, and then -in the View Tools- click on Zoom Extents
All Selected button.
|
|
|
To
create some interesting landscape features, let's use a Skeleton
Line set from our Demo Library.
You
can open the library two ways:
- click
on the Library Window button at the lower left of the
WorldBuilder interface; once the window is open, right-click
to open DEMO.ODB.
- click
and pull down to WorldBuilder Demo Library.
In
the Library window, select reef03 from the skeletons
group. Drag reef03 into the Scene Tree.
|
| Open
a new Camera Viewport by double-clicking on Camera01
in the Scene Tree. Using
the Move manipulator, drag the camera in any of the 4 viewports,
checking the image composition in the Camera Viewport.
|
|
 |
We
want to include more of the scene within the camera frame.
This is like using a 'wide angle' lens with our camera.
In
the Property Tree, select Projection and increase the FOV
(Field of View) parameter from the default value of 48
to 60.
|
Because we're going to be simulating a diffuse overcast lighting scheme,
position the light high in the scene. Be sure to leave enough areas
in shadow so that the scene is not lit too ‘flatly’.
Check
your lighting position by using Smooth OpenGL rendering in the Camera
View. |
