PixelCharStudio3D is a complete, Blockbench-style workbench for creating, painting, rigging, and animating low-poly anime and PSX-style 3D characters - directly inside Unity!  

Designed specifically for indie devs, JRPGs, retro games, and procedural crowd generation, it combines parametric mesh sculpting, a decoupled pixel-art UV atlas, in-editor 3D painting, 2-bone analytic IK posing, and one-click exports to rigid Humanoid/Generic prefabs, FBX, or Blender/Mixamo formats.  

💡 Ultra Lightweight: Typical output is ~560 triangles with a 128×128 skin sheet. The PSX mode drops down to ~300 tris for a true 90s retro silhouette!  

📸 Showcases & UI Breakdown

Full-featured Unity editor workbench: Parametric sliders, real-time 3D viewport, and 2D skin sheet painting in one layout!

🛠️ Key Features

1. Decoupled Fixed Atlas (Paint Once, Morph Anything)

The Core Concept: Geometry dimensions and UV layout are completely decoupled.  

Drag sliders to tweak height, head scale, leg girth, or hip flare - your painted skin PNG never stretches or distorts. 

Resample skins across different detail levels (16px to 128px per part) without losing your art

2. Parametric Bodies, Rounding & Clothing Shells

7 Presets: Chibi, Chibi F, Standard, Adult F, Adult M, Tall, and PSX

Selective Rounding: Interpolate box parts into smooth ellipsoids without opening gaps at joints.  

3D Clothing Shells: Separate geometry for Shirts, Sleeves, and Pants that conform automatically to body shapes and curves.  

Hats & Accessories: Add procedural hats (Witch hat, Beanie, Caps) and 2D billboard accessory slots (wings, badges, weapons) with mirror-pair support

3. Built-In 3D Texture Painter

Paint directly onto the 3D model in the viewport or edit the flat 2D skin sheet.  

Full Pixel Art Toolset: Pencil, Eraser, Bucket Fill, Eyedropper, Tile Clamping, Mirror X, and Shade Brush.  

Sculpt Hair by Erasing: The hair shell wraps over the head. Erase pixels to cut custom hairlines, fringes, and cuts - what you erase reveals the face underneath 

Expressive, anime-style facial features and hairlines painted directly on the mesh.  

4. Animation Suite & Analytic IK

Dedicated Animation Workbench: Built-in timeline window for posing and keyframing.  

Analytic IK: Drag hands or feet and arms/legs solve automatically with elbow/knee pole controls.

20 Generated Starter Clips:

General: Idle, Walk, Run, Wave, Jump, Bow, Cheer, Cute, Sit, Death.  

Combat: Attack, Defend, Cast, Use Item, Injured.  

Life-Sim / RPG: Till, Water, Craft, Gather, Fish.  

Engine-Friendly Baking: Bakes continuous Euler rotations - no weird 358° rotation flips when importing into other game engines or Blender

📦 What's Included?
