Warping With the SpeedBump Macro
This macro creates a nifty bump with a shadow on your title.
Utility Macros
The following macros let you address Maya’s Z-depth output, float elements used with
the screen node, and let you manipulate the DOD.
MayaZ Depth Macro
The MayaZ macro converts the -1/z values that Maya outputs for the Z channel.
ScreenFloat Macro
This macro lets you use the Screen function with float elements. You have to set the
high value. If you use the normal float, you get negative artifacts, both aesthetically
and numerically.
CopyDOD Macro
This macro copies, adds, or intersects the DOD between two images, and lets you set
the background color.
