This is a fork of PolyQuilt by Sakana3, the original addon can be found here: https://github.com/sakana3/PolyQuilt
Its a tool to help speed up the process of manual hand retopology, similar to tools like Retopology Flow and Quad Draw.
For a faster and easier way to toggle retopology overlays/custome retopology themes, snapping settings and more, this add-on can be used: https://extensions.blender.org/add-ons/key-ops-toolkit/
Fixed some space drag operations that would result in a error, also its set to None now by default.
This extension does not require special permissions.
Best Retopology tool on the market.
The only problems are that the knife tool is broken when using it with mirror functionality selected (not modifier). And when using the mirror modifier with clipping enabled, the vertices still go through to the other side.
