Sculpt Tool Kit is an add-on that introduces a suite of workflow improvements for sculpting. It includes boolean operations with line, polygon, and freehand slash tools for slicing objects. The add-on provides specialized masking tools allowing users to extract geometry, split masked areas, decimate unmasked regions, and add temporary rigs for posing sculptures. Additionally, it features an envelope builder for generating base meshes from armatures and a simple remeshing system for creating quad-dominant meshes.
