Problem importing/exporting X2D files in Phocus

[ndwgolf]

After importing my X2D files into Phocus and letting Phocus do its magic and convert the files from .3FR to .FFF the file size goes down from say 230MB to 160MB (Perfect).
Problem is when I export them out of Phocus as 16 bit TIFF files to import them into Lightroom they increase to ~600MB,..........what am I doing wrong???
Thanks

°You can import the converted FFF-Files direct into Lightroom.
