After creating your Maya x-ray cameras and loading undistorted video into Maya, you can use this set-up to manipulate the scene. Alternatively, you can use the Pan and Scan tools for Rotoscoping.
1. Type "camControl("camera_name")" in the command line, where "camera_name" is the name of one of your x-ray cameras. This creates a control panel in the channel box that allows you to move around and zoom in and out in that camera view.
2. Select all of the "camControls" in the channel box. If channel box is not visible, locate these tools (upper right side of screen): The one located to the right will reset the channel box back to normal.
3. Type "ac" in the command line. This creates an "attribute collection" window that allows you to change the camera controls without being in the channel box.
4. Do the same for the second x-ray camera view. You should now have an attribute collection window with the controls for both x-ray cameras.
5. Select one of the bones that you want to rotoscope and assign a new material. Select the new material in the attributes window to change the color if desired. The bone shade we often use has the following values: Red = 1, Green = .945 Blue = .753. We usually use a lambert or phong E texture.
6. Go to windows, rendering editors, hypershade. In the hypershade, select the new material.
7. With the new material selected, type "transControl" in the command line. This creates a control for the transparency of the bone.
8. To move the control for transparency, select the control in the channel box, then go to the attribute collection window, go to edit and select add new attribute. This adds the transparency control to the attribute collection.
9. If you have multiple bones that you want to rotoscope, you can apply the material you created to other bones by assigning "existing material".
