Permablend earns a place in the Superhive library for handling proximity-based material blending without manual painting or node setups, with full Cycles and Eevee support.
Permablend is a Blender add-on from Egret Studios LLC focused on proximity-based material blending. It generates transitions where objects are near each other automatically, so there's no need for manual painting or complex node setups. The effect updates in real-time, giving direct feedback as you work.
The add-on supports both Cycles and Eevee with full rendering support, and provides real-time viewport preview. Version 1.1.0 adds several controls: Invert Blend flips the blend direction on any object, a Vertex Group Mask lets you paint exactly where blending happens, and a Normal Direction Filter restricts blending to surfaces facing a specific direction — suited to snow, moss, and dirt. Displacement Blending blends displacement between two materials, and Custom Blend Style exposes dedicated controls for amplitude, threshold, and radius.
This release also resolves banding artifacts, so sharp stripes are gone and blends transition smoothly across geometry. Permablend is a Blender Extension listed under the GPL license and is compatible with Blender versions 4.0 through 5.1.
Permablend is best for blender artists who want automatic material transitions between nearby objects across Cycles and Eevee.
Permablend is completely free to download and use.
Permablend is compatible with Blender versions 4.0 through 5.1. It is offered as a Blender Extension and lists as Blender Extension Compatible, so it can be installed as an add-on. Because it covers this range, it works across several recent Blender releases. Check the developer's page for the current published details before installing, as version support and packaging can change between releases of the add-on.
Permablend lists full rendering support for both Cycles and Eevee, and it provides real-time viewport preview for feedback while you work. The render engines used are Cycles and Eevee. This means the proximity-based blending is available in either engine rather than being limited to one, and the viewport preview gives you a live look at transitions as you set up the effect on your objects.
Permablend generates transitions where objects are near each other automatically, so no manual painting or complex node setups are required. For finer control you can add a Vertex Group Mask to paint exactly where blending happens, use the Normal Direction Filter to restrict blending to surfaces facing a specific direction, or invert the blend direction. Custom Blend Style also exposes controls for amplitude, threshold, and radius when you need precise adjustment of the effect.
Permablend is listed as free in this catalog and is distributed under the GPL license. For current licensing terms and any purchase options, refer to the developer's page maintained by Egret Studios LLC. A demo video is also available if you want to see more about the add-on before deciding, and the developer's page carries the most up-to-date information on availability and support.
