Hello,

I have been scattering objects on objects for more than 20 years now, and for this I have used literally every tool and software that existed throughout the years.

Blender particles and vertex / face instancing were a half solution, a workaround.

The implementation of geometry nodes made it fun and pleasing to scatter things with Blender for the first time.
So I gathered all my scattering experience, favorite options, test cases and methodology and I made this geometry nodes setup :)

It can be used to scatter polygons on polygons. Abstract, plants, nature, rocks, buildings, antennas on buildings, whatever.

Current Features:

• object / collection instancing
• instances realized into real geometry
• instance minimum distance
• viewport optimization (number of instances displayed in viewport)
• viewport proxy instances (bounding box / convex hull)
• weight painted instance distribution
• slope angle distribution
• relative (base geometry) height distribution
• textured instance distribution
• complete instance rotation control with rotation snapping
• complete instance uniform and non uniform scale control
• wind effect on instances
  
• camera culling
• level of detail (lod) functionality, 3 levels
• raycasting control of instances
  
• additional tools to quickly and easily reset the origin of selected objects, select objects of similar size / volume and generate UV maps of selected material of selected object and set up dynamic weight painting of instances (brush) on base geometry (canvas)
  

And I plan on adding new functionality whenever I imagine any new trick.

enjoy :)

Installation:

For example scenes and tutorials check the ia scatter blendermarket documentation page or the iraisynn attinom youtube channel

version history:

version 1.82 (9 November 2022)

• added merge distributed points by distance (works better than distance min in most cases)
• added texture and weight affect scale option
• added reset origin (z=0) button

version 1.71 (29 september 2022)

• added convex hull geometry output
• added raycast target geometry input
  

version 1.64 (24 September 2022)

• added master on/off button
• added secondary wind
• added face camera (useful when scattering image planes)
• added make canvas and make brush menu buttons (for weight dynamic painting)
• fixed math in slope angle distribution
• fixed LOD error
• removed translation and distance from face as redundant. using random min and max values results in same behavior

version 1.58 (28 August 2022)

• added wind system

version 1.51 (19 august 2022)

• changed the scaling behavior. now uniform and non uniform random scales are simultaneous and additive
• cleaned up the geometry node tree

version 1.45 (9 August 2022)

New features:

• added distance and random distance from face along normal setting
• added buttons under ia tools for resetting the origin of the selected object (center and lowest point) with center finding method option
• added button under ia tools for selecting all objects that have similar size/volume to the currently selected object (with similarity tolerance setting)
• added button under ia tools for smart UV projection of selected objects selected material
• added option to modify the UI (split 3d viewport and open up geometry node editor) after ia scatter is added to the scene

changes:

• ia scatter button now adds a new copy of the geometry node group with randomized seed on the selected geometry
• added internal timing for each script operation for optimization and benchmarking purposes. the timing results can be seen in the console

version 1.34 (21 july 2022)

• fixed align to normal, rotation and scale math to respect transform/center/pivot change (based on user feedback)

version 1.32  (20 july 2022)

• added instance translation and random translation feature
• fixed rotation math for better z axis behavior when align to normal is selected
