Blender 4.5 and newer. It is installed as a Blender extension (Edit > Preferences > Get Extensions > Install from Disk).

The live material works in both EEVEE and Cycles, edge highlights included. Baking textures always uses Cycles, which the add-on switches to and back automatically.

Yes. Rocks are triangulated, have a clean UV map and come with baked albedo, normal, roughness, AO and edge textures. The normal map is OpenGL (green up): use it as is in Unity and Godot, and enable Flip Green Channel in Unreal.

Yes. The rocks and textures you generate are your own work and can be used in any project, commercial included. The add-on itself is released under the GPL license.

Every rock is driven by a seed. The same seed and settings always rebuild exactly the same shape, and the material has its own seed too.

Yes, but changing a Rock Generator setting rebuilds the mesh and replaces manual edits. Finish the shape with the settings first, then edit the mesh.

Baking renders five textures with Cycles. On a CPU a 1024 px bake takes about one to three minutes. Lower the resolution or samples, or enable your GPU in Preferences > System > Cycles Render Devices.
