How to remove the background in USRBIN 3D plot?

Dear FLUKA experts,
I‘d like to know how to remove the current background in USRBIN 3D plot, it would be better if I could get a pure white background.
Furthermore, is there a way to export the 3D plot to .png files in flair? ( I used to get .png files through screenshots.)


The checkered background of the 3D view in the Flair interface cannot be removed or changed. However this background becomes white when exporting the viewport to an image.

To export the viewport into an image, click the export button of the geometry tab. Then make sure you have selected the correct viewport. For an export to PNG format, select type “Image” then choose a file name and finally click “Export”.

I have successfully exported the image,thanks.
