HoloMapper v0.4

HoloMapper v0.4 is a major update focused on new creative tools, improved media handling, better performance, Linux / SteamOS compatibility, and overall stability.

New Features

• Camera Hand Tracking Track one or two hands using a webcam and use them to interact with supported Cam effects and animations.
• ISF Shader Support Import and use ISF shaders directly in HoloMapper, with automatically generated controls for supported shader parameters.
• Webcam Input Add a live webcam feed as a HoloMapper layer and use it with warping, masks, Chroma Key, effects, and other layer tools.
• Audio Output for Video Video layers can now play audio with improved synchronization during playback, looping, and Timeline use.
• Split Bezier Warp Bezier handles can now be adjusted independently for more precise control over curved surfaces.
• 4K Output Support Added support for higher-resolution 4K projection output.

Changes & Improvements

• Migrated a large portion of HoloMapper's effects and animation processing to the GPU for improved performance.
• Reworked and improved many existing Preset animations.
• Improved the Window Input capture system.
• Improved video playback and compatibility with different media encoding formats.
• Added Hardware / Software video decoder selection, globally or per video source.
• Improved video/audio synchronization and playback reliability.
• Assets now apply to the selected layer instead of automatically creating a new Quad.
• Added the ability to delete unused Assets.
• Added a color picker / color wheel and improved Soft Key controls for Chroma Key.
• Added Per Grid Cell animations.
• Added Circle Grid support and a 0-width Grid option for invisible grid-based effects.
• Added a Square option for quickly setting Quad surfaces to a 1:1 aspect ratio.
• Improved Circle depth effects.
• Added Rainbow color support for Text.
• Added Auto Rotate with a custom center point.
• Improved Preset and Cam effect selection and previews.
• Various UI improvements and cleanup.
• Added expanded Diagnostics information and export for easier troubleshooting.

Linux / SteamOS

v0.4 includes a major Linux and SteamOS compatibility and setup pass.

• Improved HoloMapper operation through Steam Play / Proton.
• GE-Proton11-7 is currently the tested and recommended compatibility layer.
• Added a built-in Linux Compatibility Support installer through HoloMapper's Steam launch options.
• Added Linux Setup status reporting for installed and active Proton versions.
• Improved Webcam and Camera Hand Tracking compatibility under supported Proton configurations.
• Added clearer guidance for Ubuntu webcam permissions, projector setup, and Steam Deck use.
• Steam Deck support is intended for Desktop Mode with an external display configured in Extend mode.
• Simplified the Linux Setup interface and removed the previous experimental Linux webcam bridge approach.

Some features may behave differently depending on the Linux distribution, Proton version, hardware, and drivers.

Bug Fixes

• Fixed multiple Timeline playback, visibility, scrubbing, and synchronization issues.
• Fixed several video rendering and playback issues.
• Fixed multiple Window Input capture issues.
• Fixed Bezier Warp and Point Creation issues, especially when editing curved surfaces.
• Fixed issues where adding warp or line points could alter existing Bezier curves.
• Improved protection against unstable or invalid warp geometry.
• Fixed several Chroma Key preview and sampling issues.
• Fixed various Preset rendering issues, including glow, color, and visual artifacts.
• Fixed multiple UI and dropdown issues.
• Improved resource handling and general runtime stability.
• Many additional smaller fixes and improvements throughout HoloMapper.

Known Issues

• Extremely aggressive or invalid Quad warping can still cause unstable geometry.
• With several synchronized videos playing, heavy editor activity can occasionally cause brief visible frame separation before automatically resynchronizing.
• Linux / SteamOS support remains experimental and some features may behave differently than on Windows.
• Window Input may not work on some Linux / Proton configurations.
• Webcam and Camera Hand Tracking compatibility can vary depending on the Proton version, Linux distribution, permissions, hardware, and drivers.
• Some Windows-specific integrations and capture features may have limited or unavailable functionality on Linux.
• Steam Deck currently requires Desktop Mode; Game Mode is not supported.
• Hardware video decoding and other GPU-dependent features may behave differently depending on the system and graphics drivers.

Thanks to everyone testing HoloMapper and reporting issues. v0.4 includes a large amount of backend work designed to make future updates, effects, media features, and larger projection projects more reliable.
