Installation

The required free disk space for the installation is given in parentheses.
The installer will only create shortcuts, register supported file extensions and thumbnails in Windows Exporter, but otherwise the application is fully portable.
All installation packages can be optionally open and extracted manually via 7zip, WinRAR or similar software.
If you want to manually register the supported file extensions (without running the installer), run the following command (⊞ Win+R):
Windows 64-bit
installation_dir\x64\register_ext.exe
Windows 32-bit
installation_dir\x86\register_ext.exe
If you want to manually register thumbnails in Windows Explorer (without running the installer), run the following command (⊞ Win+R):
Windows 64-bit
installation_dir\x64\register_shell.bat
Windows 32-bit
installation_dir\x86\register_shell.bat
The main executable is called lib3, although advanced users have few more applications that can play with:
sceneconv is command line utility to import lib3 or third party formats and output lib3 or json files.
imageconv is command line utility to convert and process images.
denoiser is command line utility to denoise rendered images.
ior is command line utility to convert complex IOR tabulated data to artistic friendly base and tint color.
sysinfo is command line utility that can display system information.
lz4cli is command line utility that can work with LZ4 archives.

Uninstall

Run the following command (⊞ Win+R). Or just find and execute this file within Windows Explorer:
Windows 64-bit
installation_dir\x64\deregister_shell.bat
Windows 32-bit
installation_dir\x86\deregister_shell.bat
Delete the installation folder.
