Hartface

ClothDrop Reborn is a single-click cloth simulation add-on for Blender that drapes cloth over any object in seconds. Select a plane and drop it, or draw one directly in the viewport.

Aiming Helper is a Blender add-on from Hartface for visualizing and aligning sights on weapon models. It lets game asset artists verify that eye, rear sight, front sight and target line up correctly directly in the 3D viewport.

Mesh Filters is a Blender add-on from Hartface that provides a combinable filter stack for selecting faces, edges, and vertices in Edit Mode. Filters can be stacked together, and the process is non-destructive.
