I NEED TO CONVERT MY WGS COORDINATES INTO MY LOCAL ONE. I NEED TO USE NAD83 / FLORIDA WEST (FTUS) + NAVD88 HEIGHT (FTUS). EVEN THOUGH I CAN CHOOSE THIS OPTION IT SAYS ITS NOT SUPPORTED. I MADE SURE TO DOWNLOAD GEOID 18, CONTERMINOUS UNITED STATES
NAD83(2011) (EPSG::6319) TO NAVD88 HEIGHT (EPSG::5703) FROM AGISOFT WEBSITE AND PUT INTO MY GEOID FOLDER, I ALSO RESTARTED METASHAPE AND PC AND NO LUCK

Hello Talon AS,

in my case, it works I have the us_noaa_g2018u0.tif geoid copied in Geoids folder and I define the CS as in 1stattachment. Note take care of 7 parameter TOWGS84 parameters to ave accurate transformation. In 2nd attachment you see the coordinates of point 1 printed in NAD83(2011)_Florida West and WGS84....

The following prj gives the CS definition that you can import into Meta...

It should work...
Best Regards,

If the desired coordinate system is based on NAD83 opposed to NAD83(2011), then it is required to convert the downloaded geoid file from NAD83(2011) to NAD83 coordinate system and then use via Add Geoid button (though Datum Transformation Settings dialog), once the desired compound coordinate system is selected.
