It reduces file size of f3d files after export.

Flare3D files can be compressed so as to speed up file download and save space. This compression involves no loss and allows for perfect reconstruction of the original objects after decompression.

You will achieve best results when compressing 3D objects and animations, as textures in JPG and PNG formats come pre-compressed.

F3D files can be compressed at any time, even after being exported, by right-clicking the F3D file and then selecting the “Compress” option. This action can also be performed from the “File” menu of the “Flare3D Explorer”.
