Geometry Node Particle System V4

This is an Geometry Node based particle system for Blender 4.1.

This is still a bit experimental, and will be updated over time.

Nodes Included:

Main:

• Particle Simulation V4
• Particle Instance
• Particle Trail
• Child Particle

Velocity:

• Velocity Edit
• Velocity to Surface
• Velocity to Curve

Extra

• Align Instances to Camera
• Self Transform (used for ignoring object transform)

Sub Groups:

• Set Particle Info
• Particle Solver (applies a frame's changes)
• Particle Size Collision (Uses Size)
• Particle Raycast Collision (Size ignored) (V1 and V2 being tested)

Named Attributes Used:

• Age
• Lifetime
• Life (normalized age)
• Mass
• Velocity (particle offset per frame)
• Will Delete
• Rotation (experimental)
• Size (Size of particle)
  

These can be referenced in the shader editor or other nodes.

*Collisions are WIP, suggestions welcome.

*Particle rotation is not ready.
