Hi Mark, yes there is a flip command in v2. But there is no icon set up for it yet, to use it you need to set up a keyboard shortcut for it, or type it in by hitting the tab key first and then typing flip.

But usually the best way to avoid flipped surfaces is to try and make your model made up of solids rather than open surfaces.

When a model is a closed solid, then MoI is able to automatically determine an inside and outside direction and you should get things all oriented.

When things are just open surfaces, then there isn't an automatic way for MoI to determine which side is supposed to be the "outside".

Also another thing that can help even if you have open surfaces is to use Edit/Join to glue together any surfaces that touch at common edges. Pieces that are joined will all have a consistent normal direction between them and even if it needs to be flipped (if it is not a solid) it will be easier to manage larger pieces instead of all individual small pieces.


Also probably the absolute easiest way would be to alter the Kerkythea material to be a two-sided material rather than one-sided. Usually with renderers there is an option for that and with that set up you would not need to worry about it.
