STL Renderer 1.1.0

A big under-the-hood update: everything that was documented now actually works, files that used to fail now load, and the app no longer needs anything extra installed.

Download

  • STLRenderer-Setup-1.1.0.msi – installer. If you have 1.0.0 installed it gets replaced automatically.
  • STLRenderer-1.1.0-portable-x64.zip – no install needed, just unzip and run. Settings are kept in that same folder.
  • SHA256SUMS.txt – checksums.

Drag-and-drop works exactly as before: drop one or more STL files (or a folder!) onto STLRenderer.exe and you get <name>_png.png next to each one.

What's fixed

  • Command line options now work. -c, -bg, -a, -o and -s were documented but ignored. They're validated now, and there are new ones: --width, --height, --transparent, --opaque.
  • The PNG uses the resolution you set. Saving from the GUI used to export at the window size.
  • The exported image looks like the preview. The lighting used to be different.
  • Images with odd widths no longer come out skewed.
  • More STL files load: binary STLs whose header starts with solid (common from some CAD exporters) used to fail. Broken/truncated files are rejected safely instead of misbehaving, and a failed file no longer wipes the model you had loaded.
  • Folders and filenames with accents or ñ now work everywhere (open/save dialogs, drag-and-drop, command line).
  • .STL in uppercase is no longer ignored.
  • Consistent output names: always <name>_png.png, no matter how you opened the file.
  • Batch errors are reported: the exit code is 0 if everything rendered, 1 if any file failed, 2 for invalid options.
  • No more Visual C++ Redistributable needed: the exe runs on a clean Windows install.
  • The app now installs as 64-bit.

Good to know

  • Settings now live in %APPDATA%\STLRenderer\config.ini (the install folder isn't writable). Your old 1.0.0 settings aren't carried over.
  • Command line options only apply to that run and don't change your saved GUI settings.
  • Requires Windows 10 or newer and an OpenGL 3.3 compatible GPU.

Command line examples

STLRenderer --width 1920 --height 1080 -c 0.9 0.4 0.1 --transparent parts/
STLRenderer -o preview.png -a 45 bracket.stl

Run STLRenderer --help for every option.
