Voxel Heat Diffuse Skinning earns its place in the superhive library for tackling a case that stops Blender's built-in bone heat weighting: non-seamless characters built from separate components. Rather than replacing the built-in tool, it pairs with it. The developer's page hosts a full tutorial and a demo video.
Voxel Heat Diffuse Skinning is a Blender add-on from Mesh Online aimed at three skinning problems: the 'bone heat weighting: failed to find solution for one or more bones' message, body parts or accessories that get ignored and need manual vertex weight fixes, and results that stay unsatisfactory after long manual work.
Traditional heat map diffuse skinning only handles watertight meshes. The voxel heat diffuse skinning algorithm converts a non-seamless character into a solid statue and diffuses heat through it to produce natural vertex weights. Because traditional heat map skinning handles detailed areas such as fingers and toes well, the add-on combines both approaches. The voxel grid is built with ray tracing technology, and a physically based energy attenuation algorithm drives the result.
After selecting all sub-meshes and the armature, the interface appears in the animation tab of the tools shelf, where one mouse click completes the skinning. Built-in Joint Alignment Tool, Surface Heat Diffuse Skinning, and Corrective Smooth Baker add-ons round out the package.
Voxel Heat Diffuse Skinning is best for rigging characters assembled from separate, grouped components that are not watertight and cause Blender's built-in bone heat weighting to fail.
Voxel Heat Diffuse Skinning is completely free to download and use.
Voxel Heat Diffuse Skinning is built for exactly this case. Traditional heat map diffuse skinning only handles watertight meshes, which often fails on characters assembled from separate, grouped components. The voxel heat diffuse skinning algorithm converts a non-seamless character into a solid statue and diffuses heat through it, producing natural vertex weights. It addresses the 'bone heat weighting: failed to find solution for one or more bones' message, body parts or accessories that get ignored, and results that remain unsatisfactory after long manual weight fixing.
Voxel Heat Diffuse Skinning appears in the animation tab of the tools shelf once you select all the sub-meshes and the armature. From there, one mouse click completes the skinning. The add-on also includes a Joint Alignment Tool for positioning joints: select the armature, enter EDIT mode, rotate the viewport to a proper angle, switch to orthogonal view, and move the joints to their proper positions on the current 2D view plane.
Voxel Heat Diffuse Skinning bundles three built-in add-ons: a Joint Alignment Tool, a Surface Heat Diffuse Skinning add-on, and a Corrective Smooth Baker. It also uses a physically based energy attenuation algorithm and builds its voxel grid with ray tracing technology. Together these make up what the developer describes as a complete skinning solution, combining the voxel method with Blender's built-in heat map diffuse skinning for results across both broad forms and detailed areas.
Voxel Heat Diffuse Skinning is listed as free in this catalog. For current licensing terms and any details on distribution, check the developer's page on superhive, where you will also find a full tutorial and a demo video. The developer notes that maintenance work on the add-on is very minor, so it does not take part in the 'Support Period' plan.
