Tutorial 2 Intermediate Skills 71

Note: Generally, it’s better to define motion blur settings for individual transform

nodes. You can set motionBlur to 0 in the Globals tab to temporarily turn off all motion

blur calculations, and thereby speed up your workflow. Just remember to reset the

global motionBlur parameter to 1 when you need to preview the effect in the Viewer or

render final output.

The first two motion blur parameters in the Globals tab are multipliers of the motion

blur settings for the individual transform nodes. Entering 0 for global motionBlur, for

example, internally multiplies all the motionBlur settings in the transform nodes by 0,

which effectively disables all motion blur. On the other hand, entering a global

motionBlur setting of 2 doubles the values. Set the global motionBlur to 1 to restore

motionBlur settings on the individual nodes.

Importing Photoshop Files

Shake handles several different file formats. The FileIn node is the standard method for

“reading in” (importing) images into the Node View. However, Photoshop files are

handled a bit differently. You can use the FileIn node to read in Photoshop files, but if

your file has multiple layers, it’s better to use the import feature designed specifically

for Photoshop. Give it a try.

First you’ll use the FileIn node to read in a Photoshop file. Then you’ll compare the

results to the Photoshop import feature.

To import a Photoshop file using the FileIn node:

1 Create a new script by choosing New Script from the File menu.

2 Add an Image–FileIn node.

3 Browse to the $HOME/nreal/Tutorial_Media/Tutorial_02/images/field_wawas directory,

then double-click the background.psd file.

Shake inserts the Photoshop file as a single image.
