Andres Stephens, known as Trinumedia, has released Smart Mesh Blend, a Geometry Nodes-powered add-on for Blender and Bforartists. It blends surface normals across multiple mesh objects within a chosen collection, using proximity as a guide. The effect is applied via a setup wizard triggered by dragging the asset from the Asset Browser into the scene. This removes the need for manual, object-by-object configuration.

The tool offers displacement at intersections, adjustable blend distance and blur strength, and retains existing materials or material overrides. Post-setup, settings are available in the modifier stack, or the underlying Geometry Nodes network can be edited directly. A bake option joins the geometry and writes normals into the mesh.

Version 1.0.0 is available now via Gumroad starting at US $5.

What Blending Multiple Mesh Objects Means

In 3D graphics, each mesh’s vertex normals determine how its surfaces respond to light. When separate meshes meet, their normals often differ sharply, producing visible seams in shading. Blending normals averages these vectors along the boundaries, giving the appearance of a single continuous surface without altering mesh topology.

Traditionally, this requires either manual vertex normal editing or merging the geometry through boolean or remesh operations. Smart Mesh Blend automates the process across a whole asset collection using Geometry Nodes, enabling rapid previews of seamless shading. This can save time when experimenting with complex assemblies such as terrain patches, mechanical kitbashes, or organic character parts, before committing to time-intensive clean-up and retopology.

The Bforartists Connection

Smart Mesh Blend works with both Blender and Bforartists, an open-source fork of Blender designed to improve usability for artists. Bforartists retains Blender’s complete 3D toolset—covering modelling, animation, simulation, rendering, and compositing—but changes the interface approach. The fork emphasises a mouse-driven workflow, replacing Blender’s dense menus and hotkey focus with a cleaner, icon-rich UI, left-aligned labels, improved tooltips, and customisable toolbars. It also includes a simplified keymap for complete viewport control via mouse input, though Blender’s default keymap remains available. Importantly, Bforartists maintains file and add-on compatibility with Blender, so projects and extensions work identically in either application.

Test Before You Commit

As with any third-party extension, artists should test Smart Mesh Blend in controlled conditions, verifying results under production lighting and rendering before deploying it in live pipelines.
