I still have a question about the normal direction.
It's not that I'm completely stupid, but my english level don't help me sometimes to really undertand some technical thinks.

Let's say that an object looks right when I do the meshing, I mean I can clearly see the polygons, the backface curling work well ... however when I open
the .obj in my rendering software (actually modo), the normals are inverted. Is it something that happends sometimes and I have to deal with ? or it's also something
I can call a bug :) ... the problem actually is that I can't really flip the normals in modo because the vertex normal map is not inverted, so I still have something wrong.
I can only force to render everything in 'double side' mode, and that can be a problem later with some transparency surface.

Hi PaQ - if your object is a fully closed solid like your example here, then that is a bug.

But if your object is not a fully closed solid (if it has some edges that are open and not attached to another surface), then that is not a bug - it isn't generally possible for MoI to automatically determine an inside and outside type region from an open surface.

Can you please report this to the modo developers? When you perform a flip in Modo they should also just flip the vertex normals as well instead of leaving them the same.

I had previously assumed that MoI did not need flipping functionality inside of it because it seemed to me that programs that specialized in polygon editing should be able to handle a pretty basic operation like flipping orientations without messing stuff up....

But that has turned out to be a problem in Modo and Cinema4D as well.

So I would like to add in something to let you see the orientations of open objects and flip them around, I have not quite figured out where to put that yet.

Ok now I get it about the fact the object has to be closed.

Sure I will !
