"These nodes make the procedural workflow easy"

Extra Nodes:

Falloff Nodes:

• Fourteen falloff nodes provide straightforward control over the field based on the falloff.

Utility Nodes:

• There are utility nodes: Loop Node, Integration Node, Selection Based on Attribute, 3D Viewer Node, Vector Viewer Node, Index Viewer Node, and Guide Curves node (NEW, for Blender 3.5x or higher).

Procedural Particle System with Forces Nodes:

• It is an advanced Procedural Particle System based on the Simulation Nodes of Blender 3.6x and Blender 4.0x. It has 17 forces to control the dynamics of these particles, and many advanced features (Demo Video).

Falloff Tracer Node:

• It generates lines based on any field's 2D/3D Curl or Gradient. You may also use Field Nodes for further control.

Memory Falloff Node:

• It stores attribute value with time. The stored attribute can be animated with a Factor or Time Duration. It is based on the Simulation Nodes of Blender 3.6x and Blender 4.0x.

Field Nodes:

• There are seven field nodes to generate fields based on Mesh, Curve, etc.

Bake

The Blender 3.6x (or higher) has the baking feature for the Simulation Nodes of the Geometry Nodes. To bake: Select the Object having the simulation nodes -> Physics Tab -> Simulation Nodes (Bottom) -> Press Bake. It will bake and store the cache next to the project file.

About

This tool is made with geometry nodes and can be used in Blender 3.3x, 3.4x, 3.5x, and 3.6x. The Procedural Particle System and Memory Falloff node are only for Blender 3.6x.

License

You can use this tool in any of your projects (non-commercial or commercial).

You may not redistribute the geometry node group itself, for free or commercially.

Happy Noding... :)

Updates

15/08/2023:

• Released the Extra Nodes for Blender 4.0.

• Fixed the Mesh Face Falloff node.

• Improved Mesh Volume option for Procedural Particle System.

07/07/2023:

• Released the Procedural Particle System v2.1 for Blender 3.6.

• It has Mesh Surface Factor and Mesh Volume Factor in the Particle System Output node for the smooth projection of particles.

• The Collision Force node has a new Stick To Surface feature, which allows to stick the particles to a collision surface with the help of the new Set Stick Position node.

• Generalized the Emitter Velocity, now it will work in both emitter modes: Start-End Frames and Continuse. The Emitter Velocity is renamed as Animated Emitter. The Animated Emitter along with the Emitter UVMap are moved into the Emitter Setting.

• Added new Particle Action node. It outputs the action (a boolean) when the particle is born or gets dead. It also outputs the Current Time (time starts when the particle is born) and After Time (time starts when the particle gets dead).

27/06/2023:

• Fixed the particle emission when emitter geometry does not have UVMap.

24/06/20223:

• Released the Procedural Particle System v 2.0 for Blender 3.6.

• It has many new features: Frames / Continues (density) particle emission, easy workflow, and new forces nodes.

• Multiple Particle Systems are possible with the same object.

• Particle Tracer and Particle Info Nodes.

  
  

05/06/2023:

• Guide Curves node: No need that input fur/curves should be pointing in +z-axis.

04/06/2023:

• Added Guide Curves node which can direct the fur/hairs with the curves (input fur/curves should be pointing in +z-axis).

  
  

25/05/2023:

• Released the Particle System v1.1 for Blender 3.6.

• Fixed the velocity issue. It may break the old files, be careful.

• All forces consider the particle mass.

• Added new Particle_Particle_Force. Particles can repel or attract each other.

• Make the node setup more efficient.

  
  

01/05/2023:

• Updated the files for Blender 3.6 experimental build on 1st May 2023.

22/03/2023:

• Added Memory Falloff node based on the Simulation Nodes of Blender 3.6 experimental build.

• Updated the Particle System for Blender 3.6 experimental build.
