Ultimate Rock Generator for Blender

Game-ready rocks in minutes: shape, erode, sculpt, texture, optimise and export without leaving Blender.

From a single pebble to a cliff face, stylized or realistic, every rock is non-destructive until you decide it is done.

New in 2.1

• Blender 5.x support. Tested on Blender 4.5 and 5.2 LTS, and it still runs on 4.0 and later.
• Installs as an Extension on Blender 4.2 and later: Get Extensions > Install from Disk.
• Fixed: Musgrave layers crashing on Blender 4.1 and later. They now use the equivalent Noise Texture setup.
• Fixed: errors when generating seams or unwrapping, and when editing Decimate Ratio, Target Faces or the Distorted Noise controls.
• Fixed: selecting sculpt brushes on Blender 4.3 and later, the Sun light deselecting your rock, and the Stylized material ignoring your sliders.
• Your custom material presets now survive add-on updates.
• New: Support (Discord) button in the main panel.

Upgrading on Blender 4.2 or later: remove the old "Ultimate Rock Generator v2" add-on first, then install the new ZIP.
