Exporting to PLY

I have noticed that many versions of Blender do not have importing of COLLADA format.

In MKI3D I have implemented exporting to  PLY - Polygon File Format,
which is supported in more versions of Blender.

Mki3dgame on Flathub

https://flathub.org/apps/

Mki3dgame is now available as a Flatpak pakage on Flathub.

If you have flatpak installed on your Linux, then io.github.mki1967.mki3dgame can be installed on your system with the command:

flatpak install --from https://flathub.org/repo/appstream/io.github.mki1967.mki3dgame.flatpakref

or it can be installed locally in your user account:

flatpak --user install --from https://flathub.org/repo/appstream/io.github.mki1967.mki3dgame.flatpakref


(On Linux Mint, Flathub is now integrated into the software manager.)

After installing,  you will probably find the icon on the desktop menu for starting the programs (should be in the games section).
You can also run it from the command line:

flatpak run io.github.mki1967.mki3dgame


Thanks to Flathub people for creating org.freedesktop.Sdk.Extension.golang and to  developers who helped me in  preparing the metadata for the flatpak-builder.
