Nurbs Surface Problem - 2 side things don't work

[lite4ya]

Here's some images.



As you see, mapping onto Nurbs model(Alias Work) doesn't work.
I tried to search for the solution 'bout that, found one - Double Sided Material Type thing, and that didn't work, too, as you see in the last two images(flipped faces changed...)

I experience these situations occasionally when I do the modelling with Rhino, Alias and etc. Using 'Normal' Modifier - unify on, flip off - in Max works, but the faces change little awesome...

Comments please.


ps. Sorry for my English

Anybody who has a comment about this...?
The setting in the image was wrong... or something...

Max seems to have some problems with meshes imported from other programs. Do a search for Rhino and you will find some solutions.

I have the same problem when I duplicate an already grouped object.

Delete your node before duplicating or delete node after and group again.
This will resolve your problem (in my case it work... I hope it will be the same for you).

Can´t you just select those parts of the surface and flip their normals ?

[natty]

i think thats all thats needed here ... have turned show normals on ?.... you need to unify them .. so they are going all in the same direction

[eltioseba]

he can, but max transform the nurbs to mesh when fliping.

Not the greatest solution but you can transform the surfaces to high quality mesh, then unify/flip them. Its not a clean solution but is something.

I have the same problem here.

[samuel_bubat]

It normally doesn´t need to be transformed to a mesh when flipping nurbs
normals.

If you are lucky (depending on the import/export) Then you can
select these flipped surfaces (not faces) on subobject level and just flip their normals.
It´s very unlikely that some normals are flipped within a single nurbs surface. But you never know what the importer does

The only solution I ve found is to flip the normals once you've transformed the nurb into a mesh. If you need to change it you have to come back to rhino... You can check the surface orientation in rhino though, to make sure it's ok before you import it..
