Fix Small Prims by Emma Nowhere

Now updated to use LLGetLinkPrimitiveParams.

In Second Life, no prim can be less that .01 meters in any given dimension (width, length, or height). When you try to resize an object, you often find you can't shrink it below a certain size. This is because one of the prims in the object is already at it's minimum size in one of it's dimensions. This script checks every prim in an object and slightly increases the sizes of the prims which are already at their smallest possible sizes, so that the overall object that the prim is part of can be scaled down. This usually lets you reduce the object in size by an additional 20%. You can repeat the process several times if you're not able to shrink the object enough on the first try.

In the instructions below, we'll refer to your object that you want to resize, such as a necklace or a tree, as a "linkset". We call it this because the object consists of a linked set of prims, rather than one single prim.

If you're not familiar with how prims and linking work, please read the following wiki pages:

How to use with menu:

  1. Install this script in the root prim of a linked set of prims (aka "linkset")
  2. Type /1fsp to show the menu
  3. Hit the "Fix" button to fix all the small prims
  4. Resize the linkset object to the desired size with the Editing Tools
  5. Type /1fsp to show the menu again
  6. Hit the "Finish" button to remove the script and finalize prim sizes


(Advanced) How to use with chat commands:

  1. Install this script in the root prim of a linked set of prims (aka "linkset").
  2. Type /1fsprun to fix all the small prims
  3. Resize the linkset object to the desired size using the Second Life editing tools
  4. Type /1fsprestore if you need to return them to their original sizes (you should only use this for no-copy objects, otherwise make a copy before you start)
  5. Type /1fspcleanup to remove the scripts from the linkset and finalize prim sizes


IMPORTANT: You should always make a backup copy of the object before using this script.
