OT-Dev Alpha — 2026-09-20

Unofficial OT-Dev alpha build for review and testing.

Build

• Source: main at e8c43df4e922d5268d0acf69a398093c1f9aafed
• Windows portable package built and tested by GitHub Actions
• Build date: 2026-09-20
• Package SHA-256: a9f67a0fdbdb394227d8cb8a3f8c14a0fc588b714e7a4f43e33a3243193304e6

Highlights

• Animated SVG export, with external or embedded raster frames and an option to render the scene first
• PDF loading as raster levels through a configured pdftoppm converter
• Multipage raster PDF export for the selected full-color raster level or the entire rendered scene
• Type Tool history now preserves font, style, and size, with improved canvas-click placement and shaped-text baselines
• Configurable default tools for startup and new scenes
• Tape Tool stroke-direction preservation with an optional remembered confirmation
• Crash fixes for empty LUT activation and missing PLT/TZP color metadata
• XDTS scene-initialization, restored room sizing, vector-thumbnail, Darker-theme, and numeric-roller fixes
• Scientific-notation support in expressions
• Current OT-Dev 3D FX, GLB rendering, lighting, 3D LUT Bake, build branding, and opt-in session recorder

Notes

This is an experimental pre-release, not an official OpenToonz release. Back up production work before testing.

PDF loading requires pdftoppm.exe to be configured under Preferences > Encoder/Decoder. PDF export uses Qt directly and does not require Poppler.

Animated SVG export is appearance-based when raster frames are used. Embedded frames can substantially increase the SVG file size.

The session recorder remains disabled unless the user explicitly enables it.

OT-Dev Alpha — 2026-09-17

Unofficial OT-Dev alpha build for review and testing.

Build

• Source: main at cec4f3543dffab6bc0a737e88e86e0300266fc0d
• Windows portable package built and tested by GitHub Actions
• Build date: 2026-09-17

Highlights

• Editable Type Tool text history stored in typetool.ini
• UTF-8 plain-text and Markdown source import for the Type Tool
• Unicode-safe Type Tool input, history recovery, editing, and glyph generation
• Emoji and combined-character editing as grapheme clusters with system-font fallback
• Current OT-Dev 3D FX, GLB rendering, lighting, and 3D LUT Bake work
• OT-Dev build branding and opt-in session recorder

Notes

This is an experimental pre-release, not an official OpenToonz release. Back up production work before testing.

Full-color emoji output is not included. Vector output uses available font outlines, while Toonz Raster output renders resolved glyphs as grayscale ink.

Markdown files are preserved as editable source in this alpha. Applying Markdown styling to generated Type Tool glyphs is planned as a follow-up.

The session recorder remains disabled unless the user explicitly enables it.
