WorldBuilder 4 Tutorials - Volcano - Page 1: Getting Started

IThis is a pretty simple project.  It uses some of WorldBuilder 4' s more familiar tools, but in a slightly different way.

Note that this tutorial is designed to be used with the free downloadable Demo version of WorldBuilder 4.  Certain features such as file and rendered image saving are disabled in this version.  If you would like to compare your work with the scene created in this tutorial example *.awb files are available for download along with this tutorial.

Let' s start by opening WorldBuilder 4.  The default scene includes the basics for creating our environment: a Camera, a Parallel Light source, a Landscape and a Compound Sky element.

Note: To speed up rendering, the AltoStratusClouds2 and SunDiskWithHalo1 components have been hidden.  They can be ‘unhidden' at any time by right-clicking on them in the Scene Tree.

Add a Skeleton Line set from the Library.  Choose volcano3 from the skeletons group and drag it into the Scene Tree. 

Render the scene in the Camera Viewport, to observe how our Skeleton Lines are deforming our landscape.

Note: the camera and light angles in this tutorial is different from the one in the default scene file. See the example scene file volcano_tutorial.awb for precise camera and light Location & Direction property coordinates.

Now let' s fine-tune the geometry of the landscape.

For Landscape0, use a Settings > Points value of 1024.

Enable Cast Shadow (so that our mighty Volcano throws a mighty shadow) and Shielded Polygon Culling (so that WorldBuilder' s rendering engine will ‘ignore' those parts of the landscape terrain mesh which are not visible to the camera, thereby saving render time).

Note: The light source(s) in this tutorial use the Shadow Map feature. For more information about Shadow Maps see the WorldBuilder Basics tutorial.

Under Landscape0' s Skin property, set Evolution to 70; this will give our volcano a relatively smooth slope angle.

Now set Roughness to 93; this will keep the slope surface itself from appearing too smooth and featureless.

Render the scene again.

Our volcano may look a little strange at this stage.
That's because we're not quite done with adjusting its geometry.
