Use Click+Shift+click (click, and then Shift+click) to choose several
contiguous files, and Ctrl+click to choose non-contiguous files.
5 Choose the BIP files you want the software to use for motion synthesis,
and then click the OK button.
The files are added to the graph as clips. Each clip is automatically named
after the file from which it's derived.
NOTE For best results, especially with simulations in which bipeds are to turn
at different angles, use as many different turning clips as possible. A minimal
setup would include separate left-turn and right-turn walks at angles of 45,
90, 135, and 180 degrees.
The next step is to add transitions among the clips so character studio
knows which actions can proceed to and from other actions. You can do
this manually for greater control, but for initial testing, you can save time
by letting the software add and optimize transitions automatically.
6
Click the Synthesize Motion Flow Graph button. This uses the first
30 percent and the last 30 percent of each motion to create transitions.
The graph now shows arrows to and from each clip, as well as from each
clip to itself. If you like, delete transitions that obviously don't belong,
such as the ones from the stop and start clips to themselves.
Alternatively, you can use Create Transition to set up a custom
graph.
7
Optimize the transitions. See Transition Optimization Dialog on
page 4571.
When you solve the simulation, Crowd automatically generates a motion
flow script for the biped, based on this graph. When you have a graph
with multiple clips, as in this case, it chooses the starting clip for the
script from one or more clips you designate as random start clips.
If you want to check the integrity of transitions before continuing, do so
now. See
Customizing Transitions on page 4525.
8 Click the Select Random Start Clips button, and then click a clip.
