hello, Thanks for your answer.
In conclusion, I succeeded in exporting in .mhd format. By applying the ‘Resample to image’ filter, it became possible to save in *.mhd format.
However, a problem arose. Color coordinate values are not represented when entering this data type into Unreal Engine. Unreal plugin used ‘Raymarcher’.
Is there an option to extract color coordinates when saving in *.mhd file format?
