Blender Hair Cards: The Grid-from-Scalp Method That Saves Hours

Hair is the part of a character that makes or breaks them. Get it wrong and your hero looks like they’re wearing a plastic helmet. Get it right and suddenly the whole model comes alive. This tutorial shows a fast, grid-based approach to building game-ready hair cards in Blender 2.8 using the Hair Tools addon - and the method is clever enough that you’ll wonder why you ever bothered with cube-based workflows.

The core insight here is simple: instead of starting with a cube and subdividing your way into a grid that vaguely matches the scalp, you extrude edges directly from the scalp mesh itself. Select your edge loops, extrude outward, separate the result into a new object, and you’ve got a grid that follows the head’s topology perfectly. No guesswork. No manual alignment. Just clean geometry that knows exactly where it came from.

Building the Grid from the Scalp Up

The presenter demonstrates this with a character model that already has a scalp mesh in place. The workflow starts in edit mode: select edge loops where the hair part should sit, extrude them outward into flat strips, then use P > Selection to separate those strips into standalone grid objects. Two grids get created - one for the front hair, one for the back - then marked as sharp and joined with Ctrl+J.

This is the moment where the Hair Tools addon earns its keep. Running Curves from Grid Surface converts that joined grid into hair curves automatically. The curves follow the scalp’s topology because the grid was born from it. No manual placement of thousands of strands. No pain.

From there it’s about organization. Layer 1 gets thick, opaque coverage with high strand width and lower strand count. The presenter edits the curve profile to control shape and thickness, adjusts root partition and uplift values, and uses subdivide on selected roots multiple times to increase control point density. Proportional editing gets used constantly - with “Connected Only” toggled on or off depending on whether you want to drag neighboring geometry along for the ride.

Layering for Realistic Volume

One layer of hair cards looks like exactly that: cards. The magic happens when you stack them. Layer 2 starts as a duplicate of Layer 1 (Shift+D), then gets its own material with Alpha Hashed blend mode for transparency. The presenter copies shader nodes from Layer 1, deletes the default material on the new layer, and pastes the nodes in. Quick, clean, consistent.

The UV editor comes into play here with an opacity texture - sourced from a free ArtStation asset pack by “Sin House” - defining which parts of each card are visible and which fade into nothing. This is where the flyaway strands happen, the loose hairs that break up the silhouette and sell the illusion of real hair.

Intersection between layers is the enemy here. The presenter spends time manually adjusting strand positions to prevent cards from clipping through each other. It’s tedious but necessary. Proportional editing with “Connected Only” disabled helps move roots without dragging distant geometry around.

Mirroring and the Center Part Problem

Once the hair is built on one side, it’s time to mirror. All layers get joined, duplicated, and mirrored to the opposite side with Object Mirror. But here’s where things get interesting: gaps appear at the center part line. The presenter fixes these by duplicating individual cards and snapping their roots to the head mesh using face snapping.

Speaking of snapping - roots should snap to the head mesh, not just the scalp. This gives cleaner placement and prevents that floating-hair look that screams “game asset from 2004.” The presenter also demonstrates thickening hair dramatically by editing the curve profile and pushing vertices outward. One layer with enough thickness can sometimes replace the need for multiple layers entirely.

Creating Hairlines and Final Touches

The tutorial closes with a quick demo of extruding a hairline directly from scalp edges. Same technique: select edges, extrude outward, separate, run Curves from Grid Surface. This extends the grid workflow to create widow’s peaks, recession patterns, and other natural hairline shapes without any new tools or workflows to learn.

Throughout the recording, the presenter is candid about the results. The hair “looks terrible” by the end, they admit. But the point was never the final render - it was the technique. The grid-from-scalp method is positioned as a faster alternative to traditional cube-based workflows, especially when your triangle budget tops out around 16K and you need game-ready hair yesterday.

The presenter also makes mistakes on camera and self-corrects, which is honestly refreshing. Too many tutorials pretend everything goes perfectly the first time. Real work involves false starts, Blender crashes (“Thundert likes to crash”), and computer lag. Seeing someone roll with it and keep moving forward is good medicine for beginners who think they’re the only ones struggling.

Level Up Your Blender Setup

Bottom line: If you’re building hair cards for games and you’ve been starting from cubes, try extruding from the scalp instead. The Hair Tools addon does the heavy lifting once you give it a grid that actually matches your character’s head. Layer for volume, mirror for symmetry, snap for clean placement, and don’t be afraid to let the results look rough while you’re learning the technique. Perfect hair takes practice. The grid-from-scalp workflow just gets you there faster.
