Fix Small Prims

About

Fix Small Prims by Emma Nowhere

Shrinking linked prims is difficult because no prim in the linked set can be smaller that .01 meters in any dimension. This script finds the smallest prims and increases their size slightly so that the link set can be sized down.

1. Install this script in the root prim of a linked set of prims (aka "linkset") 2. Type /1fspsetup to copy copy scripts into all the prims in the linkset 3. Take the linkset into inventory 4. Re-rez the linkset from inventory 5. Select the linkset and choose "Set Scripts to Running in Selection" under the Tools menu 6. Type /1fsprun to fix all the small prims 7. Resize the linkset object to the desired size 8. Type /1fspcleanup to remove the scripts from the linkset
