Surface Blend earns its place for handling material transitions between assets and surfaces using geometry nodes and shader mixing rather than manual masking. The real-time follow and non-destructive workflow let you reposition assets and refine spread, strength, and noise without rebuilding anything.
Surface Blend is a free Blender add-on for blending an asset's material into a ground or landscape surface based on how close the asset sits to the surface. Geometry nodes drive the mask and shader mixing handles the transition, keeping the result non-destructive. The workflow runs in three steps: pick the surface, pick the asset, then hit blend and adjust spread, strength, and noise for a natural result.
Move or rotate the asset and the blend follows in real-time, with no re-baking or manual updates. You can stack multiple materials in a controlled 1→2→3 order using one-directional blending to build layered surface transitions such as paths fading into grass fading into dirt. Procedural noise breaks up clean, artificial edges, and you control its scale and amount for irregular borders.
Controls for Spread, Strength, Noise Scale, and Noise Amount update live in the viewport. Everything sits in Blender's N-panel sidebar under the MK Blend tab, with clear buttons to assign surfaces and assets. Surface Blend works with Blender 4.2 and up, including Blender 5.0.
Surface Blend is best for blending an asset's material into ground or landscape surfaces in Blender, including layered path-to-grass-to-dirt transitions.
Surface Blend is completely free to download and use.
Surface Blend works with Blender 4.2 and up, and that support includes Blender 5.0. The add-on relies on geometry nodes and shader mixing to build its proximity-based blends, so a Blender version in that range is what it targets. Once installed, its controls appear in Blender's N-panel sidebar under the MK Blend tab. If you run an earlier release, check the developer's page before installing to confirm it fits your setup.
Surface Blend places its controls in Blender's N-panel sidebar under a tab named MK Blend. The panel keeps things organized with clear buttons for assigning your surface and your asset, so there's no complex setup to work through. From there you pick the surface, pick the asset, and hit blend. Sliders for Spread, Strength, Noise Scale, and Noise Amount let you adjust the result, and each one updates live in the viewport as you move it.
Surface Blend updates the blend in real-time as you move or rotate an asset, so there's no re-baking and no manual updates to run. The transition tracks the asset's position and orientation automatically, letting you place rocks, props, and other assets and watch the ground blend adapt live. This live follow is driven by the same geometry nodes and shader mixing that power the proximity-based blend, and the whole process stays non-destructive.
Surface Blend is listed as free here in the catalog, and it's described as a completely free Blender add-on. For current licensing terms and any conditions on use, check the developer's page before you download. It also comes with documentation to help you get started, and the setup is meant to be quick: install the add-on, assign a surface and an asset, then blend. The full feature set covers proximity blending, layered blends, procedural noise, and real-time controls.
