1. Let's create some bangs. A series of tassel-shaped objects are placed next to each other in this tutorial. These objects have not been changed into triangular polygons because doing so increases the number of substructures and a large number of substructures require more calculations. Nevertheless, objects are eventually converted into triangular polygons for rendering. Surfaces are split into a hair root section, which will be fixed, and a tip section, which will be in motion.
The boundary between these two sections is made uneven so that the tips will not move identically. Hfront.lwo is the example, along with the head object face.lwo.
2. Add a motion to the object in Layout. A turning motion has been created. See mdc04mox.lws.
3. Once the motion is completed, open LW_MotionDesigner
from Plug-in Options panel under "Generics". Select the bangs object hfront.lwo from the Object
panel, and switch Target ON. This will import the object from Layout
as well as the keyframed motions.
4. Set the parameters required for each surface
on the Surface panel. Set Fixed (for b0, the root section) to ON, and enter
a value of 500 for the substructure.
5. Use substructures for b1 (the tips of the hair) and
adjust each parameter while watching the motion. The spring coefficient
is set to a small value (100) to achieve a flexible motion. To
prevent abrupt bending at the connections to the fixed section,
enter 3 for Smoothing. This will perform the smoothing process
three times on the areas between the spring coefficient values of
500 and 50 to prevent bending.
6. Let's set the wind and the gravity. Since
these variables are not necessary at this time, enter zeroes. The scene file that reproduces the settings from 3 to 6 above
is mdc04.lws.
7. Start the calculation. If you are satisfied with the result, save the data in a file. Specify the filename by SAVE MDD button, and save the data. H.mdd is the sample.
8. Go back to Layout and open the Object properties panel of the bangs object. Select MD_Plug as the displacement map plug-in and load the saved file. Also, select Key-Move=OFF at this time. See Mdc04.lws.
9. Manipulating the time slider should animate the bangs. Render as desired.
