Nvidia Bug. Earlier versions of UVLayout were not loading files for some hardware/driver combinations on Nvidia GPUs. One user noted that drivers up to version 516.59 worked OK for them, but 531.61 and above crash out. Releases of UVLayout since 2024 have fixed this problem.
Download and open the ZIP file below to install the Demo version of UVLayout for Windows platforms. If Windows Defender blocks you from running the EXE, click More info to enable the install. See Installation_Guide:_Windows for full installation instructions

After installation, you can run UVLayout by drag’n’dropping OBJ files onto the “UVLayout Demo” icon.
