A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

- Fixed the parts/monitor selections so that they don't change their drawing order accidently when changing other parameters at the view's top limit. - Output render now ceeps more precise track of frames and time rendered. Also rendering buffer queue is now visible for larger resolution rendering that will cause queuing.
Larger update for 2023 New feature: - Change the parts drawing order in any of the multi part module pages (Figure, Arabesque, Source) by dragging the monitors at the top middle monitor view. Changes: - Noise oscillator rewritten: now noise has more possible resolution and actual effects on the Figure part parameters. - Source parts show some file/stream/cam information before turning them online. Bug fixes: - Figure parts importing .gif files now reads alpha/invisibility correctly. - Figure frame size change now safe while rendering the part. It shouldn't crash the app in any case. - Frame sn
This update makes the recursive Arabesque parts multi-threaded; Each part is now processed in it's own thread, without affecting the overall framerate even with heavy recursions - given that enough CPU cores & power is available.
Audio device selection is now split to two; device for input and device for output. This should solve problems with devices with only input ports or only output ports, and make all sorts of audio routing setups possible.
Fixes back Spout video sharing library functionality. Tested only in Windows 10.
- GIF file loader rewritten, gifs with transparency also work now. - Performance optimization (Windows max stack size increased)
Fixed microphone / audio input permission request to macOS.
Quick fix for library link error that caused crash
Preventing some startup crashes.
This menacing issue had been reported to occur only in some mac systems: Now a corrupt settings.ini file should not crash the app. Changing any render settings or loading any external files will overwrite the settings file with a valid one. You might still lose your default video/picture/gif/project/etc search paths.
Updates most linked libraries to the latest (NDI, Spout, etc) with some new features and changes from user feedback: Audio Device selection added to init screen (you can now select the device or start without audio features) Oscillator maximum frequencies increased to 25Hz (especially for noise oscillator) MIDI devices are now activated by selecting them (the app won't hijack all available MIDI devices automatically anymore, but only those selected from the device list) Parameter value tooltip now draws differently and less glitchy on some systems. New render mode (Rough Pixels vs Smooth Pixel
There was a very common crash issue with opening any USB cameras or most encoded video files on macOS Catalina, because the app used older Qt and OpenCV libraries that had no idea of the new safety protocols in macOS. The fix got delayed because of numerous other issues that came with Catalina.. Catalina is pain, really. For some funny reason they removed support for all old video libraries and nothing works, unless you deploy everything yourself, and what's more funny is that the currently "required" app notarization cannot be done for any included pre-built third party libraries. So the app
Update with fresh libraries. Mac version should now ask camera permissions from macOS, and not crash when opening camera stream to a Source part.
Big update that makes the Windows version of Cathodemer 64-bit with fresh OpenCV & NDI libraries. Lots of UI tweaking and bug fixing for Windows. Most things look a lot better and run faster. Note that Steam should replace ALL installation files, so if there's any trouble running after update, remove all local files and reinstall. Windows 10 64Bit is now the primary development platform instead of MacOS.
New: - Internal video feedback amount (found at OpenGL Settings on Extra tab) Changes/Fixes: - Init screen has now option for renderer mode (Pixel or Texture) as some rare crashes might be due using Pixel mode, so the app can now be started with Texture mode. - Figure frame max size increased to 512x512. Large image edit view also made more clear and optimised. - Arabesque pattern and fractal modes now align seamlessly on screen. - Hopefully some stability issues fixed due patches on Qt libs.
