Texture Repeater
Texture Repeater. Observes textures and texture parameters on the prim. As soon those have changed, updates other prims in the linkset to repeat the changes. This allows the user to texture the covered or hard to aim faces of that prims.
The script copies the texture UUID and parameters given the face 0 to the face 0 on of every other script in linkset. Than the texture UUID and parameters of the face 1 to the face 1 of other script and so on until the face 5. Further faces are not repeated but that is easily extensible.
The script was created for my GlassBox mesh tutorial – where we create mesh prims with faces that cover others completely and make them quite hard to texture inworld on regular way. The script was published here in hope it is also usable other wise, but also to keep my blog post shorter.
Usage
Create a box (or other appropriate form) via build tools and put the script into - this turns the prim into repeater tool. Now you can prepare the prim faces by texturing, or just link it with all prims you want bulk-texture. The face textures are copied immediately by linking. If needed you can now texture the repeater prim – all texture parameters are copied to other prims than.
The repeater must not be the root prim of the linket. You can also use two or more repeaters (not recommended), the script copies only changed parameters and avoids so a permanent texture updates by multiple repeaters.
After usage, click the repeater, the script will ask for link permission. If you accept, the repeater will unlink and destroy itself, but leaving back the textured linkset inworld (if you doubt prim loss, please comment out the llDie() command.) If you put something into the repeater prim, like a notecard, texture or another script, the repeater script skips self-destroying to prevent loosing that unexpected content.

// The lists allow to terminate a ping-pong change of textures // when two repeaters are linked by mistake, but also prevent // change of values that are always changed. To do so we fill // up the lists by dummy values that are never something used // for texture settings. This way the script will notice the // difference between the set texture and stored dummy value.
