| Building and Animating a Two sided Newspaper by James White |
 |
While working on Spoonman ([Tens de ter uma conta e sessão iniciada para poderes visualizar este link] I was given the task of putting together a newspaper that was double sided but also paper thin. The problem was getting the two different sides to not pass through one another during animation. The end result was relatively simple but effective. Step One: Create a rectangular polygon using the box tool in the desired size and give eight segments using the numeric panel down the X and Z axis. (These segments will be used later in animation). Name this “Top” Step Two: Copy and paste the polygons into layer two and flip it. Name this “bottom” Step Three: Now cut layer two and paste it into layer one. You now have a one poly thick double sided sheet of paper that will allow both sides to be textured and not cross through to the other side during animation. (A1)  If you plan to animate this paper you should now create a bone setup in an X shape from corner to corner. (A2)  Adding Realistic Creases (optional). The paper I put together needed to look as if it had been folded several times to give the appearance that it had been kept in the main characters pocket. First: Select the different point lines on the left half of the paper shown in the picture below. (A3)  Second: Move these points up the Y axis just above there original position. (A4)  Third: Repeat this with the other side now moving the points down the Y axis. (A5)  Fourth: Now select the middle horizontal points moving the top half up and the bottom half down. (A6)  This process can be repeated to give the desired number of folds as needed. If more realistic folds are desired you can make very close knife cuts to where you plan on making the creases. This will give you more maneuverability with the folds. You are now ready to move your paper to Layout for texturing and animation. Note: Don’t forget to save often.  Animating your paper. Animating the paper is relatively easy. Many different movements can be used to make your project come to life. For Spoonman the paper needed to simulate the look of being dropped from a rooftop. This was accomplished first by doing some research on how a piece of paper would actually move if dropped in a semi windy environment. A piece of paper was dropped over and over in front of a large fan to capture the movements. I suggest using this method of research for the look that you are going for. I found that the easiest way for me to animate this paper was to first get the paper in the starting position and set a key frame and then move it to the end position and set another key frame. After this is done you can move the paper to follow whatever path you need (B1)  Once your motion path is set you can start putting movements to your paper. To go for a subtle realistic look you should change the shape of the paper by bending the corners in the direction that the wind is supposed to be blowing it (B2)  To give it the look of being suddenly blown in another direction bend the corners in the same direction to give it a parachute look. (B3)  The most important thing to remember is to keep the direction of the folds and bends in sync with the direction that the wind would be blowing. This tutorial should give you the basic tools to get you animating paper right away!
