• Sculpt Bridge Tool v1.0 (SuperhiveMarket) is a Blender sculpting helper built with Geometry Nodes that lets you connect two areas of a mesh by generating a “bridge” (strand) or carve a tunnel/“punch hole” between them—super useful for creature/character sculpting when you want to quickly form connections without manual modeling. It includes several shaping options (listed on the product page as Bridge Tool / Squeeze / Gravity / LDiv), plus a Symmetry mode (your mesh needs to be perfectly symmetrical—using Blender’s Symmetrize operator beforehand is recommended). It’s compatible with Blender 4.0+ and is positioned as a fast, ZBrush-style workflow for bridging forms while staying in sculpt mode.
