📖 Quick Start Documentation

1. Importing the Node Groups

• Open your project file.
• Go to File > Append, navigate to Dissolution_Particles_Suite.blend or Dissolution_Mesh_Suite.blend, open the NodeTree folder, and select:
  • Dissolution_Mesh_to_Particles
  • Dissolution_Objects_to_Mesh
• Alternatively, mark the node groups as Assets to access them directly from your Blender Asset Browser.

2. Applying to Target Geometry

1. Select your target 3D object and add a Geometry Nodes modifier.
2. Select the appended dissolution node group from the dropdown.
3. If using an animated or rigged character: ensure the Geometry Nodes modifier is placed below the Armature modifier in the modifier stack so deformation is evaluated first.

3. Shading & Transparency Setup

• For Particle Dissolution: Assign the included M_Dissolution_Blend material to your object. The node group exports an attribute named dissolve_fac (0.0 to 1.0) into the shader editor to synchronously drive transparency/alpha alongside the particle spawn.
• For Mesh Dissolution: The node generates native polygonal geometry on output. Assign any standard material directly to the modifier.

4. Driving the Dissolution Progression

• Manual Keyframing: Keyframe the Dissolve Threshold / Progress slider from 0.0 (fully intact) to 1.0 (fully dissolved).
• Spatial / Controller Empty: Connect the location of an external Empty object into the Controller Location socket to dissolve the geometry interactively as the Empty passes through the mesh.
