In Object mode, 3Dview > Add (Shift + A) > Mesh > LowPoly Rock
Options
Number:
Number of rocks to create.
Size:
Rock size.
Size Ratio:
Rock proportion along x, y, z axis.
Midlevel:
Displacement mid level.
When you set one of Size Ratio too low, you would get weird rock shapes.
Setting this parameter lower might solve the problem.
Noise Center:
Center position of voronoi texture used inside this addon.
Affect base rock shapes.
Simplicity:
Reduce poly count and make meshes simple.
Sharpness:
Make rocks sharper.
Edge Split:
Add edge split modifier and apply shade smooth.
This option would prevent unpleasant shading on tessellated Ngons in rendering.
Random Settings:
You can set Size Range and Size Ratio Range as well as Random Seed.
Size of auto generated rocks varies between these ranges.
Advanced Settings:
Display advanced menues.
Keep Modifiers:
Don’t remove modifiers.
With this option on, you can see what this addon does behind the scene.
You know it would be really great if you could add the option of auto-generating several different types, the user could select how many and the detail level, for example. These could then be used to “fill” scenes with Rubble or particles. Even if they had a sort of seed value to give slight variations with no user input, unless of course you wanted it.
Love the script. it is great for when you are just testing out ideas and need something to populate a scene.
Ok I just tested this out with 2.74 it works fine for generating one rock. My question is where are the options. I looked in the toolshelf and in the N-key pop out but I cannot find anything related to it.
Never mind I found it it was under the toolshelf but I had the bottom of the toolshelf shrunken so far down I did not see it.
Has anyone tested this with 2.78c. I have used it with 2.79 and it works just fine. But when I used it with 2.78c I get on rock in the 3d Viewport but I cannot for the life of me find the settings panel in the toolbar. This might be my fault since I have used the change categories script to consolidate a lot of toolbar panels and get fewer tabs so that they all fit into one window. But let me know if anyone else has the problem.
I know it is on the toolbar but what tab IN the tool bar???
Never mind I found it. After setting the change category plugin to get less tabs in my blender editor window certain plugins diappeared but I just switched to a different scene layout and the interface for this plugin reappeared
