Petik - Retopology Patch Maker is a retopology add-on for Blender that helps you build low-poly quad meshes. Instead of placing one polygon at a time, you click on a high-poly surface to define geometry patches, letting the tool fill in the space. Each patch supports up to six sides and a variable number of vertices per side, and you can build a mesh from scratch or connect new pieces to preexisting geometry.
Version 2.0 introduces multi patch, so you can create and control multiple patches at once. Place the control lines and Petik works out the rest: Ctrl+Right Click selects the active control point, then you click for a new point or Right Click an existing vertex to draw a control line between them. When the control lines form loops, a patch is created automatically. Scroll to set the vertex count on each new side, drag corners to adjust features without pinching or stretching, and press H to hide the UI.
Version 2.0.4 adds Petik Line, a stand-alone feature that treats a control line like a lattice for edge loops, smoothing multiple vertices from a few control points. Documentation and Discord support are available from the developer.
