For those who don’t know the tool: Unity is a real time engine used for games, virtual production and interactive content. Polybrush was its in editor mesh and vertex painting tool. The new alternative is designed as a Unity editor extension for painting and modifying meshes directly inside the engine.
RealBlend Mesh Painting and Creation is an editor extension available via the Unity Asset Store. It is designed to provide mesh editing and painting workflows directly inside the Unity editor, reducing the need to round trip to external DCC applications for certain environment art tasks. RealBlend supports vertex painting, mesh sculpting and procedural geometry creation within Unity.
Vertex painting and layer blending
RealBlend enables vertex colour painting on meshes inside the scene view. Vertex colour painting stores colour data per vertex, allowing artists to drive shader blending, material variation or masks without additional texture maps. The tool supports multi layer blending across Unity’s render pipelines. Layer limits differ by pipeline. Up to five layers are supported in HDRP and up to three layers in URP and the Built in pipeline, according to the product description.
Sculpting and mesh editing
In addition to painting, RealBlend includes sculpting tools such as move, push and smooth. These tools operate directly on mesh geometry inside the Unity editor, allowing artists to adjust forms without exporting to modelling software. Because vertex density determines sculpting resolution, practical results will depend on mesh topology.
Procedural mesh creation
RealBlend also includes procedural mesh creation tools to generate planes, curved walls and custom surfaces procedurally. This positions the tool as more than a paint overlay system. It can be used to create base geometry and then modify or paint it in the same environment. The exact parameter controls for procedural generation are not described in detail on the Asset Store page.
Additional utilities
Along are utilities for mesh baking and a mask packer for RGBA maps. Mask packing typically combines multiple greyscale textures into different colour channels of a single texture to optimise memory usage. Procedural noise functions are also referenced for creating dirt and wear effects. These can be used to introduce variation without external texture authoring.
Pipeline compatibility and pricing
RealBlend is listed as compatible with the Built in Render Pipeline, URP and HDRP. The product is distributed through the Unity Asset Store. Pricing is 20€, currently discounted to 14.40€ (may vary by region and promotion – I don’t understand those pricing policies at all anymore, so you should consult the Asset Store listing for current pricing and licence terms. Do that HERE) No subscription requirement is indicated on the product page.
Production considerations
In editor mesh painting and sculpting can accelerate environment art iteration, particularly for blending materials, adding surface variation or shaping greybox geometry. However, tools that modify mesh data directly inside the engine should be evaluated for asset stability, version control behaviour and compatibility with existing shader setups.
As always, new tools and editor extensions should be validated in controlled conditions prior to deployment in active projects.
