Build 2022.29530
Oct 19, 2022

New Features

Bug Fixes and Improvements

• Panel opacity was not behaving consistently across panels, the following improvement have been made
  • Table COMP - Now 'Opacity' parameter works correctly.
  • List COMP - Now follows parent opacity.
  • Panel Borders now work with 'Opacity' parameter.
  • Panel opacity now works on all panel elements (OP Viewers, scrollbars, etc).

• Geo Text COMP - Fixed cases where instancing wouldn't appear in the node viewer.

• Engine COMP - Fixed Engine COMP's file parameter works correctly with VFS and URL locations
• Engine COMP - Custom file and folder parameters on the loaded component are now evaluated relative to the project, not the component. See Backward Compatibility below, this changes behavior if you have projects which use relative paths for custom file or folder parameters on an Engine COMP. This also enables VFS usage for custom file or folder parameters on the Engine COMP.
• Engine COMP / TouchEngine - Fixed crash which could occur in low memory situations with large DAT inputs.

• Text COMP - Fixed a bug with text position when only the top padding was updated.
• Text COMP - Font alpha is now correctly premultiplied when using the Specification DAT.
• GLSL MAT - Fixed crash that can occur when loading certain shaders.
• GLSL TOP - Fixed crash that would occur if an atomic counter was declared in the shader before it was defined in the parameters.
• GLSL TOP - Fixed uTDPass not being filled properly for compute shaders.

• Notch TOP - Fixed updating of Exposable Array size when Num Transform changes.
• Optical Flow TOP - Added 'Gain' parameter and improved the units output in the pixels. A value of 1 in red means the movement is from left edge of the image to the right edge of the image in 1 second. Works in non-realtime mode as as well.
• Ouster TOP - Fixed a crash when running version 2.4 firmware.
• Ramp TOP - Fixed extend left/right behavior.
• Render TOP - Fixed time reported for GPU operations being incorrect.
• Time Machine TOP - Fixed crash when input was 2D Texture Array or 3D Texture.
• Video Device In TOP - Allow cameras named 'Blackmagic Design' to be used with AVFoundation on macOS. Other Blackmagic devices should still use the 'Blackmagic' Library mode. This is needed for the Blackmagic ATEM device, which doesn't support the SDK and instead is only used via webcam interfaces.
• Video Device In TOP - Fixed hang/crash that can occur when changing cameras when using Media Foundation library.
• Audio Device In CHOP / Audio Web Render CHOP - 'Active' toggle now completely stops cooking in these operators when switched to 'Off'.
• Audio Oscillator CHOP - Fixed white noise from stopping when base frequency was left at 0.
• Object CHOP - Sample rate now matches project fps.
• OSC Out CHOP - When sending timeslice format, rate values are now sent to delineate timeslices to avoid a random number of channels appearing.
• Pattern CHOP - Fixed 'Length' parameter disabling when input operators are deleted.
• Speed CHOP - Fixed use of me.chanIndex in parameters.
• Timer CHOP - Fixed cases of skipping callbacks when leaving a zero-length segment.
• MQTT Client DAT - Fixed crash from publishing while DAT is inactive.
• Render Pick DAT - Fixed a crash that can occur in some cases.
• TCP/IP DAT - Fixed behavior of onConnect and onClose callbacks, they would trigger even if a connection was not established.
• WebSocket DAT - Fixed connection issues when using ports other than 80 or 443.

• Export Movie Dialog - Fixed checkbox state on first opening and fixed drag and drop issues with the 'TOP Video' and 'CHOP Audio' fields.
• Fixed Privacy dialogs to show password text as hidden when unlocking.
• Potential fix for hangs occurring in Nvidia 516.xx and newer drivers, particularly on laptops.
• Small fix to entries in the Help menu on macOS.
• Automatic turning on of parameters when Alt+[ or Alt+] shortcuts are used in addition to menu selections.
• Alt+MMB and Alt+RMB network zooms again, instead of creating annotates which is now restricted to only Alt+LMB.
• F10 shortcut now works properly on overlapping panels
• Fixed exporting when switching between different CHOPs and the parameter wasn't in export mode.
• Fixed panel layout order with similarly children names ie. ui1 vs ui1_1
• Allow grabbing scrollbars when panel resize edges are used.
• Fixed issue with OP Create dialog closing after pressing the tab key.
• Fixed a crash loading https://github.com/theexperiential/nodeo
• Fixed crash which could occur opening a very large window, such as a viewer for high resolution TOPs.
• CrashAutoSave.toe files will now attempt to be saved when Vulkan device errors occur.

Operator Snippets

(click Newest button in Snippets)

• JSON DAT - outputting tables now more robust and complete.
• Optical Flow TOP - flow-field example using more rational units.
• Blob Track TOP - blobs table example with timers tracking blobs that disappear and reappear.

• Geo Text COMP - example of adding text labels to dots in 3D renders.
• Text COMP - new examples for editable mode, word wrap as well as an example of Material Design Icons usage.

Backward Compatibility

• BACKWARD COMPATIBILITY ISSUE - TOX files with no file extensions will no longer load. Additionally, TOX files will always be saved out with an extension of .tox now.
• BACKWARD COMPATIBILITY ISSUE- Engine COMP - Custom file and folder parameters on the loaded component are now evaluated relative to the project, not the component. This changes behavior if you have projects which use relative paths for custom file or folder parameters on an Engine COMP. This also enables VFS usage for custom file or folder parameters on the Engine COMP.
