Hair Card Studio earns its place for consolidating hair card creation and rendering into one menu, with version 1.5 adding a fully overhauled UI and Normal, Specular, AO and Alpha map outputs.
Hair Card Studio is a Blender add-on from PixelicaCG for making hair cards. A single menu gathers the controls in one place, letting you build different hair cards and render them in a few clicks.
The strand controls cover hair amount, strand points for resolution and curvature, and independent root and tip thickness for a tapered look. You can set a fixed hair length for uniform styles or vary it for an organic feel, adjust spread for volume and distribution, and clump strands at the root or tip. Hairline shape, frizz with a scale and frizz curve, and curl and roughness add further variation. Material options change all hair colors at once, create root-to-tip gradients, and tune glossiness and sheen.
Rendering offers Low, Mid, High and UltraHigh resolution presets plus a transparent background option, along with Normal Map, Specular, AO and Alpha outputs. Lighting can be adjusted by source size, location and intensity, and presets can be saved. Version 1.5 brings a fully overhauled UI, the added map outputs, bug fixes and support for newer Blender versions. It works with Blender 3.6 to 5.1 using Cycles and Eevee.
Hair Card Studio (Hair Card Creator Addon is best for blender artists creating hair cards for character hair who want strand shape, color, lighting and map outputs handled from a single menu.
Hair Card Studio (Hair Card Creator Addon is completely free to download and use.
Hair Card Studio supports Blender versions 3.6 through 5.1 and is listed as Blender Extension compatible. It renders using the Cycles and Eevee engines, so you can work within either of Blender's built-in renderers. Version 1.5 added support for newer Blender releases along with an overhauled UI and bug fixes. If you run a version at the edge of that range, check the developer's page to confirm current compatibility before installing.
Hair Card Studio can output Normal Map, Specular, Ambient Occlusion and Alpha maps, which were added in version 1.5. For rendering, it offers Low, Mid, High and UltraHigh resolution presets and a transparent background option. Lighting can be adjusted by source size, location and intensity to see how the hair reacts before rendering. These outputs and presets are reached through the add-on's menu, so you can render results in a few clicks.
Hair Card Studio is listed as free in this catalog, and it carries a GPL license. Licensing and availability can change over time, so check the developer's page for the current terms before you rely on it. The add-on comes from PixelicaCG, who notes support for questions and problem reports. A demo video is also available if you want to look at the add-on beforehand.
Hair Card Studio lets you save your presets so you don't lose progress. The workflow centers on a single menu that gathers the strand, material, lighting and render controls, letting you build different hair cards and render them in a few clicks. Version 1.5 reorganized this into a fully overhauled UI. Saving a preset means a hair setup you like can be reused rather than rebuilt each time you return to it.
