What is rock_wall_builder?

Rock Wall Builder is an addon for Blender 3.6 and newer that generates rock walls for game environments. An addon is a plug-in that adds extra tools to Blender, the free 3D modelling software widely used by game artists and hobbyists. Instead of placing individual rocks by hand, one at a time, you configure your wall parameters and the addon assembles a wall from rock assets stored in .blend files, which is Blender's native format for saving 3D objects and scenes. You can work in either procedural mode, where rocks are placed and varied algorithmically, or prefab-based mode, where you use hand-crafted asset combinations you have prepared in advance. The workflow lets you reseed or update the wall in real time, adjusting random scale and rotation for each rock as you go, so you can quickly try different looks without starting over. This randomization helps avoid a repetitive, copy-pasted appearance across a long wall, which is a common problem when reusing the same few rock models. Wall dimensions use metric controls, letting you work in real-world units such as meters when deciding how tall or long a wall should be. Once you are satisfied with the result, the addon merges all the individual rock meshes into a single optimized object, which is the recommended approach for keeping a game scene light and fast, since many small separate objects can slow down a game engine. The README for this project is short and does not go into installation steps, screenshots, or how the addon's controls appear inside Blender's interface. It also does not mention a license, so it is unclear under what terms the addon can be used, modified, or shared. Anyone interested in trying it would likely need to look at the source files directly or contact the author for more detail.
