文档介绍：Effects (build, wave, particles)
es with some nice animation effects that can be applied to meshes. These
effects can be used to create wave effects, things appearing, fire, smoke, sparks, clouds,
shooting stars, fireworks, etc. The list is only limited to your imagination. For any of these
effects to work well, you usually need a high number of verticies. You can get this by using
the mand in edit mode.
Build Effect
The build effect is nice for simulating something building linearly along time. Text is a
good example of something you may want to use with a build effect. Blender generated
text cannot be built, but EleFont text can used.
The first step in creating a build effect is to have a mesh
that you would like to build. For this example, we will use
this EleFont text. A high vertex count is usually needed for
a nice effect. Notice the location of the object’s “center”
point. You may need to move this to get the effect you
desire depending on what you plan to do with the object
(discussed in the basic editing chapter). When bringing text into Blender from EleFont,
the letters will all be separate objects. Be careful when joining them together. You need to
join them together in a straight sequence (hold down the shift key and start at one end and
select the letters in sequence-don’t jump around). After all letters are selected, press “Ctrl”
and “J” to join them. Jumping around when selecting them to join will cause it to build
oddly.
With the object selected, go to the Object buttons, select the Effects tab, click the “New
Effects” button, then choose “Build” from the list of effects. You will have 2 things to set- the
Length and the Start Frame (how long do you want it to take to build and when in the
animation do you want it to start).
Length of the build When to start the build
Don’t be alarmed if the object disappears when you select build. You will only see the
amount of it that should be there on your c
