See Tutorial 8, “Working With Macros,” in the Shake 4 Tutorials for information on
making macros interactively or in a script.
Scripting Controls
To generate a test script, go to the
Tutorial_Misc/truck/ directory within the
Tutorial_Media directory. Enter the following command to create a script and save it as
start.shk:
shake truck.iff -outside sign_mask.iff -over bg.iff -savescript
start.shk
The truck is composited over the background, with the sign mask as a holdout mask,
and a script named start.shk is saved. The composite itself is unimportant, but the tree
structure is important. The following image shows how the script appears in the
interface.
To test the script result from the command line, type the following:
shake -script start.shk
The image of the truck is composited over the street image. The following is the code
for the script itself:
SetTimeRange(“1”);
SetFieldRendering(0);
SetFps(24);
SetMotionBlur(1, 1, 0);
SetQuality(1);
SetUseProxy(“Base”);
SetProxyFilter(“default”);
SetPixelScale(1, 1);
SetUseProxyOnMissing(1);
SetDefaultWidth(720);
SetDefaultHeight(486);
SetDefaultBytes(1);
SetDefaultAspect(1);
SetDefaultViewerAspect(1);
SetTimecodeMode(“24 FPS”);
SetDisplayThumbnails(1);
SetThumbSize(15);
SetThumbSizeRelative(0);
