When Fixed Resolution is turned on, objects that are in the group but outside of the
Canvas are cropped to the size of the group defined in the parameter.
When enabled, the Fixed Resolution parameter crops the group to the size specified in
the Fixed Width and Fixed Height parameters. This means that if the group’s anchor
point is offset, the cropping may not occur around the edges of the Canvas, and
objects may become cut off.
To fix the resolution of a group:
1 In the Layers tab (or the Timeline layers list), select the group.
2 In the Inspector, click the Group tab.
