[PixelScript] Texture changer HUD [FULL PERM] Version 1.1

Important

This system does not use link numbers.
The Receiver identifies each prim by its name.
Make sure every prim you want to control has a unique, correctly spelled name matching the name used in the HUD script.
Renaming a prim will break the connection, but link order changes will not.

Requirements

Some basic LSL scripting knowledge is required to set up and edit the scripts, such as naming prims and editing texture UUIDs.
If you need assistance, you can always contact me for help with setup or customization.

A simple, efficient LSL system for building texture-changing HUDs.

With one HUD script and one Receiver script, you can control textures, materials, and faces across multiple linked prims.

Features

• Ready-to-use example setup for quick learning
• One HUD script controls unlimited buttons

• Works with multi-prim and multi-face objects

How It Works

The HUD script sends texture change instructions when a button is clicked.
The Receiver script listens on the same private channel and applies textures to prims by name.
Each button can change multiple prims and faces in one click.
