Overview

Hybrid 2D/3D animation: draw in 3D space, model, rig and render straight to MP4.

PapaiArt Animation Studio combines 2D and 3D animation in a new way. Think of the look of Spider-Man: Across the Spider-Verse or Star Wars: Maul – Shadow Lord, where hand-drawn lines live inside dimensional scenes. The program aims to become the dedicated tool for that style.

The closed beta is over and the open beta is free for everyone. Version 1.0 was the first big milestone, with a new FBX pipeline, multi-material and multi-UV support and a GPU-buffer based renderer. The free period ends once all 1.5 features are ready.

Made something cool with it? Send a screenshot or video that can be featured, and the Open Beta watermark will be removed for you. You also get a free key when the program launches on Steam.

Features

What's inside

01 / 04

Drawing in real 3D space

2D drawings sit inside the 3D viewport, with cameras, depth and lighting. Vector strokes stay editable.

  • Drawing tracks and clips with exposure-sheet logic
  • Onion skinning with customisable ink colours
  • Pencil, Pen, Calligraphy and Rough brushes with pressure and tilt
  • Independent stroke and fill for flat-design styles
  • Drawing Layers: lines, shapes and images as separate sub-layers

Non-destructive 3D modelling

A clean hierarchy and a real-time modifier stack, with the hotkeys Blender users already know.

  • Mirror and Subdivision Surface modifiers refresh instantly
  • Interactive Bevel and Knife tools on the mesh
  • Multi-material objects and multiple UV channels with a rewritten UV editor
  • Modal G / R / S transforms with axis locks and typed values
  • A pivot dot that shows exactly what you rotate and scale around

Rigging and animation

Enough rigging to handle complex character animation, without leaving the program.

  • Inverse Kinematics, TrackTo, ChildOf and Limit constraints
  • Timeline with keyframes, and infinite undo/redo
  • Bone, skinning and animation export to FBX
  • Dockable panels: Inspector, Viewport, Timeline, Hierarchy

FBX pipeline and one-click render

Move assets in and out of other tools, and render the timeline without an external editor.

  • New FBX exporter with Blender-style presets: axes, scale, apply transform, triangulation
  • Diffuse, normal and emissive maps, PBR scalars and per-face multi-material
  • Texture path modes: absolute, relative, strip, or copy next to the FBX
  • Built-in H.264 MP4 and PNG sequence export at FHD or custom resolutions

    This is the bigger one: we added modal transforms, just like you're used to in Blender. No more dragging gizmo arrows — one key press and a mouse move, and you're transforming instantly. The basics: G – grab (move) R –…

  2. v1.0

    Papaiart Animation Studio 1.0

    We have reached the first milestone. Version 1.0 is already a highly useful tool for animators and game developers alike. What is an even bigger step forward: FBX export — brand-new system (the biggest item) New…
