LA4-6606: Content Doesn't Keep Playing If You Have Freerun & Restart During Crossfade Fadeout

Fixed an issue where jumping to Section 2 with a crossfade (e.g., 5s) caused the video layer from Section 1 to stop when Play mode is Freerun & restart. The video now plays through the transition as expected. Freerun play mode was unaffected.

Status: Done | Requesters: SUP

LA4-6604: Console.log Save Location

console.log is now saved in the Logs folder when launching LightAct, instead of ProgramData. This aligns with the console.log location used in project folders for consistent log management.

Status: Done

LA4-6603: Console.log Crash

LightAct crashes at startup if it cannot write to console.log.

Status: Done | Requesters: SUP

LA4-6590: Video Playback Issue In Rc1 Version

Fixed a playback regression in RC1 that caused delays of several dozen frames when looping and produced missed frames. The changes introduced between B2 and RC1 were reverted, restoring normal playback behavior in Masterdev.

Status: Done | Requesters: SUP

LA4-6589: Image Alpha

RC1 misrenders transparency for .png, .tga, and .tif assets. Areas that should be transparent appear as a solid, opaque color.

Status: Done | Requesters: SUP

LA4-6582: Fixtures In Canvas Maps Should Be Elevated From Legacy Back To Published

Fixtures have been restored to the non-legacy options in the Canvas maps window.

Status: Done | Requesters: SBA

LA4-6581: Autoblend Default Settings

Angle Cutoff is now enabled by default at 45°, with Linear mode turned on.

Status: Done

LA4-6572: Force Project Framerate Should Be Off By Default

Force project framerate is now off by default. Project framerate matches content, while application framerate follows the display refresh rate. When the display refresh rate exceeds the content rate, playback remains smooth, making forcing unnecessary. Note: this setting is effectively ignored once any output is enabled.

Status: Done

LA4-6568: Image Sequences Are Always Playing With The Same Framerate Regardless Of What You Set

Fixed an issue where changing the FPS of an image sequence did not affect playback speed. Adjusting FPS now correctly speeds up or slows down playback to match the selected frame rate.

Status: Done

LA4-6526: How Is Lightact Reading Png (and Tif And Jpg) Files

Color fidelity issue in LightAct when playing still images. 100% black PNGs lift, and 1px magenta/green borders appear gray in playback and export. Similar shifts occur with TIF and JPG. Now the colors are reproduced accurately.
