Introducing Poly Gen

PolyGen is a Blender add-on that transforms retopology and remeshing into a fluid, simulation-driven process. Built on a point-based simulation, it dynamically reshapes your mesh topology by scattering, evolving, and connecting points across surfaces—delivering clean, customizable quads and triangles in real time. Perfect for refining high-poly sculpts, optimizing game assets, or creating smooth, organic forms with ease.

FEATURES:

Adaptive Retopology: Paint points or draw guide paths to dynamically reshape topology, snapping agents to your mesh with raycast accuracy. Smart Meshing: Generate quads and triangles from agent positions, enhanced by optional subdivision and shrinkwrap modifiers for a polished finish. Customizable Dynamics: Fine-tune quad size, repulsion, and attraction via an intuitive sidebar, with auto-generation for hands-free updates. Minimalist Workflow: A clean UI with a progress bar and toggleable help overlay.

HOTKEYS:

ESC: Exit the simulation. RET (Enter): Generate the mesh manually. LMB: Add points (Points mode) or draw guides (Guides mode). RMB: Remove the hovered point. Ctrl(hold): Show the OptionsBar Z: Undo the last action. H: Toggle the help overlay.

Documentation:

PolyGen is a simulation-based tool for remeshing and retopologizing 3D models in Blender. It uses agents to dynamically create and connect points on a surface, forming a new mesh that adapts to your input.

Follow these steps to get started.

Installation:

Download the polygenv01.zip file In Blender, go to Edit > Preferences > Add-ons > Install from disk, select the file, and enable "PolyGen." Find the PolyGen panel in the 3D Viewport under the Simulation tab.

Workflow: Setup:Select a mesh object in Object Mode (this will be your target surface). In the 3D Viewport, open the Simulation tab and click Start in the PolyGen panel to begin the simulation. Drawing Agents:Points Mode: Left-click (LMB) on the surface to add dynamic agents that move and connect. Hold LMB to draw multiple points. Guides Mode: Hold LMB and drag to create static guide paths that influence the mesh layout. Switch modes by holding Ctrl and clicking Points or Guides in the pop-up bar near the cursor. Adjusting Behavior: In the PolyGen panel, tweak settings:

Quad Size: Controls the target distance between agents (default: 0.3). Max Speed: Limits agent velocity (default: 0.05). K-nearest: Number of neighbors for meshing (default: 10). Repulsion(Rep) / Attraction(Attr): Balances push/pull forces (default: 1.0/0.5). Clamping: Restricts agent movement range (default: 0.0, off).

Generating the Mesh: Press Enter or click Generate Mesh in the panel to create a new mesh from the agents. Enable Auto-Generate in the panel for continuous mesh updates as agents settle. Toggle Enable Subdivision for a smoother result with a Subdivision Surface modifier. Finishing: Press ESC or click Stop in the panel to end the simulation. The generated mesh ("Mesh_Patch") appears in your scene, shrinkwrapped to the target surface(Note: A shrinkwrap modifier will be added after mesh generation) Tips:

Help Overlay: Press H to toggle a hotkey guide in the viewport (default: on).

Resetting: Click the Reset(x) button to clear all agents and start fresh (warning: removes everything).

Performance: K-nearest if the simulation lags on complex meshes.

Mesh Generation: If there's missing faces you can increase the K-nearest value or go into edit mode and hit F key to fill.
