Erosion Add-On
by NM-8
The Erosion Add-On brings flow-based erosion into Blender for custom meshes. Its algorithm goes beyond the standard 2D heightmap workflow, generating rivers, lakes, vertex groups, color attributes and shading data for terrain.

A clear painting workflow paired with a single settings panel makes Soft Body Painter approachable for setting up soft body zones without touching the original mesh.
Soft Body Painter is a Blender add-on from Blender Procedural for defining soft body simulation zones by painting them onto an object. You select your object, click "Select Simulation Area", paint the zone using weight paint mode, then click "Apply" to set up the soft body and play the simulation in the timeline. The painted area is tied to a vertex group, commonly named "edges", that controls where the simulation runs.
A settings panel gathers the soft body controls in one interface, covering stiffness, bending stiffness, damping, and push/pull forces. Collision options include self-collision, face collision, and edge collision for more advanced interactions. The "Weld Points to the Original" function anchors specific parts of the mesh so they stay fixed during simulation, and a "Follow Original Object" option blends the soft body's motion with the original mesh.
The workflow is non-destructive, applying soft body physics to duplicates while keeping the original object untouched. It works with Cycles and Eevee, supports Blender versions 4.0 through 5.0, and is released under the GPL license.
Soft Body Painter is best for blender artists who want to define soft body simulation areas by painting them onto a mesh with a non-destructive workflow.
Soft Body Painter is completely free to download and use.
Soft Body Painter supports Blender versions 4.0 through 5.0 and is listed as Blender Extension compatible, provided as an add-on. It works with both the Cycles and Eevee render engines, so it fits alongside either renderer in your project. The listing shows it was published about a year ago and released under the GPL license. For confirmation of the latest supported builds and current terms, check the developer's page before installing.
Soft Body Painter follows a short sequence: select your object, click "Select Simulation Area", paint the simulation zone using weight paint mode, then click "Apply" to apply the soft body setup. Once applied, you play the simulation in the timeline. The painted area is controlled by a vertex group, usually named "edges". The workflow is non-destructive, applying the physics on a duplicate while leaving the original object untouched.
Soft Body Painter includes a "Weld Points to the Original" function that anchors specific parts of the mesh so they stay fixed during simulation. Alongside it, the "Follow Original Object" option blends the soft body mesh's motion with the original mesh for smoother results. The settings panel also exposes stiffness, bending stiffness, damping, and push/pull forces, giving you control over how the simulated area moves and settles.
Soft Body Painter is listed as free in this catalog and is released under the GPL license. Because pricing and licensing can change, check the developer's page for current terms before downloading. The add-on works with both Cycles and Eevee and supports Blender 4.0 through 5.0, so you can confirm the licensing details there alongside the version and compatibility information listed for it.
