Curve-driven brushstroke particles in Blender for OSHI

~~A particle problem~~ A production tool for OSHI

Blender
Geometry Nodes
Instancing

Following the curve — The particles flow along a curve from the small character to the glowing sphere. Reshaping the curve reshapes the whole stream.

Challenge

For OSHI, Aranza needed painted brushstroke particles she could art-direct in Blender.

Approach

We built a Geometry Nodes setup where particles travel along a curve and each particle is an instanced brushstroke, with the key controls exposed as parameters.

Outcome

The system was used to animate the brushstroke particles in OSHI.

The work, step by step

01
Brushstrokes up close
Close to camera, each particle is an instanced painted brushstroke in blues and greens, matching the painted background. Instancing keeps this many strokes light enough to work with.

In Aranza's words

Recomiendo a Mario por su talento técnico y creativo. En OSHI ayudó en el desarrollo del sistema de partículas de las pinceladas de pintura, aportando una solución que me permitió animar las partículas de forma eficaz y acertada mediante la creación de nodos en Blender.
In English
I recommend Mario for his technical and creative talent. At OSHI he helped develop the particle system for the paint brushstrokes, giving me a solution that let me animate the particles effectively and precisely by building nodes in Blender.

Mentor's note

Aranza wanted to build a procedural system in Blender that allowed her to control particle motion easily, following a curve, with useful parameters exposed and leveraging geometry nodes and instancing for great performance.
