This dialog window displays the existing motion effect rows for a preview prop or preview group. The motion effect rows are listed in the table on the left, and the prop's pixels are shown on the right.
Motion effect rows do not have to apply to all of the pixels in a prop (or group). Using this dialog, you can specify that a motion effect row only applies to a rectangular subsection of the prop's pixels.
If you click on a row in the table on the left and the selected motion effect row uses a subsection of pixels, then the subsection will be graphically represented on the right.
Within this dialog you can:
•Manually Specify a Subsection
•Copy/Paste the Motion Row Configuration
The Motion Effect Rows Dialog
Add A New Row
Clicking the "Add Row" button will add a new motion effect row to the table. The new row will use all of the pixels in the prop or group (the Subsection field will be unchecked).
Change Row Name
By default, motion effect rows are named "Effects 01", "Effects 02", etc. You can change the name of a row by clicking on the name in the table, and then typing the new name.
Add Rows By Subdividing
Using the "Subdivide" button, you can divide the pixels into rows and columns, creating a separate motion effect row for each section.
The following picture shows a 12x50 pixel tree subdivided into 2 columns and 2 rows. There will be 4 new motion effect rows created, with each subsection being 6x25 pixels

After clicking "OK" in the Create Subsections dialog, this is the result. Notice that clicking on a row in the table graphically displays the subsection on the right.

Manually Specify a Subsection
While the "Subdivide" button is very convenient for creating equally sized subsections, you might have need to manually specify subsection. You can do this by making sure the "Subsection" box is checked for the motion effect row, and then manually typing the values for left, top, width, and height.
Copy/Paste the Motion Row Configuration
You can copy the contents of the motion effect row table to the clipboard, and then use the paste button to append the data into the Motion Effect Row dialog for another prop. This can be useful if you have several pixel-based props that have the same dimensions.
