Step 9. Play. The character now has a fully fledged flowing cape
complete with secondary animation. The final character is shown
in Figure 3.21 .
The cape model used in the previous workshop was a freely available
model from Turbosquid. The original file had too many polygons to be
used for cloth rendering. It slowed down the processor such that the
application ran at a snail's pace. To reduce the polycount, the cape model
was opened with Blender, and with the object selected and placed in
Edit mode, the Poly Reducer was used as shown in Figure 3.22 . Running
this script several times reduced the cape down to fewer than 2000
