For those who don’t know the tool: Wafer is a focused 3D texture painting app that sits next to Uniform and CozyBlanket, now stretching from iPad to Windows with a stylized, hand-painted vibe.

Windows gets a new paint box

Wafer now has a free open beta build for Windows. The app started life as an iPad-only release, and this beta marks the first time the tool shows up on a platform outside iPad.

The target is clear: stylised, hand-painted, and NPR texture work. The feature set also aims higher than the word beta sometimes suggests. The app includes multi-channel painting, meaning a single brush stroke can update multiple channels at once, including colour, roughness, and metalness. The beta build on Windows aligns with the current iPad release and includes new features introduced in the Wafer 1.1 update, such as a Smudge tool.

The familiar stuff, in the right places

Wafer leans into an illustration-style workspace, then applies it directly to 3D surfaces. Brushes, layers, and masks sit at the centre of the UI concept. The toolset includes brushes, lasso clips, gradients, wet painting, and blur, all intended to operate directly on 3D geometry.

Layers follow a full layer system approach: paint layers, fill layers, editable masks, blend modes, and opacity. The workflow stays non-destructive.

Symmetry covers both 3D and 2D use, with configurable independent pivots, and mirroring across any axis. That matters for stylized assets where mirrored motifs can be a feature, not a shortcut.

Wafer also keeps 3D and 2D views in sync. You can paint on the 3D mesh with unlit, shaded, or physically based preview modes, or work directly on the 2D texture, with both views side by side.

Multi-channel painting without the busywork

Multi-channel painting is one of the headline capabilities. A single stroke can paint color, roughness, and metalness simultaneously. Wafer also supports custom channel layouts for NPR and stylized shaders, letting you define channel setups beyond the standard trio.

On the production side, the appeal is not just fewer trips between tools. It is fewer chances to drift out of alignment when a material style depends on more than one channel moving together. If you have ever tried to keep painterly color breakup and matching roughness breakup locked in step, you already know the pain. If you have not, congratulations on your serene past life.

That said, multi-channel painting only helps if it matches the rest of your pipeline and shader expectations. New tools and innovations should always be tested before use in production.

Projects, materials, and exporting with intent

Wafer supports projects containing multiple meshes, materials, and texture sets at once. That matters for anything beyond a single prop, and it also matters for stylized characters where separate materials often carry separate rules.

Asset browser built into the app

Wafer includes an integrated Asset Browser meant to keep texture resources close at hand. The browser covers stencils, triplanar mapping textures, brush alphas, HDRIs, decals, and stamps. The pitch is that these assets stay organised and accessible in a single panel, ready to apply as you work.

Within that set, stencils project patterns onto surfaces, triplanar projections wrap textures across 3D geometry, brush alphas provide custom brush tip shapes, and decals and stamps place detail textures with precision.

Performance claims, labeled as claims

The app describes extreme optimization intended to run smoothly on low-spec, older devices. It also states it can push modern hardware with up to 64K resolution per layer. These are marketing claims. It also claims brush and tool performance stays stable and predictable, with minimal impact from texture resolution, layer count, or stroke speed.

For compatibility, Wafer requires no special GPU or CPU features and targets any compatible device from the past 10+ years, listing 256 MB of RAM and OpenGL 2.0.

A published memory table provides approximate peak memory numbers for RGBA 8-bit textures with four layered materials: 150 MB at 4K, 350 MB at 8K, and 900 MB at 16K. It also notes that resolution scaling uses tiles and that available memory is the limiting factor.

One practical wrinkle: the Windows beta can be downloaded directly from the Wafer website, based on an update dated April 3, 2026. The Wafer product page itself currently shows a message that desktop downloads are coming soon.

If you are evaluating Wafer, treat the beta label like it means something. Keep a backup plan, keep your assets versioned, and do not bet a delivery date on a tool you have not run through your own texutre pipeline.

Pricing, or the lack of it

Wafer on Windows is free during the open beta period. A stable release date has not been announced, and official pricing for the stable release has not been announced either. A license server is described as suggesting the Windows version will be priced slightly higher than the iPad release, but no official price is stated.
