XMP files can contain camera profiles, tone curves, or matrix-based transforms. Many online tools only handle the “LUT1” or “LUT3D” tags. If your XMP includes a complex DNG profile, the conversion often fails silently, producing a blank or corrupted Cube file. The Ultimate Guide to Converting XMP to CUBE
