Blender Geometry Nodes Scatter Asteroids


A Simple geometry node setup to scatter asteroids instances. I have been using those rocks many times for space and sci-fi pictures. 

Updated for Blender 3.1.2 and more. 

How to use it:

choose your emit (plane and volume are set by default), starting from a plane of volume is only about the result you want to achieve, the Node tree is the same. 

move up the selected squares you want into the Selected_Rocks Collection. They will randomly be scattered on your geometry surface.

 If you want instance more frequently than others, duplicate it the appropriate number of times to increase its probability (I am working on a node for this) and add it to the same collection. 


Density: number of instances, density is relative to the surface so if you raise or shrink it, the total of instances will follow. 

Seed: Change all random values 

Min_Scale: Minimum size of instances

Max_Scale: Maximum size of instances

Magnitude: Global scale factor

Scatter: ratio of scattered instances, 0 is none, 1 is full scattering

Distance: length of scattering


About 20 small and medium rocks and three big ones. They all come with UVs but not very good, and a procedural shader with bump. 

A Fog Box collection, to add a volume shader to your scene. 

Improvements to do:

a probability node by type

a delete by volume function
