Problems with wings -suddenly blue facets can't triangulate

[MysticRain]

I've got a problem with Wings 3D.
I created a shelf and when I went to triangulating and mapping I noticed blue facets of which I didn't know where they came from. Normally blue means they are hidden, doesn't it? I didn't do anything like this, I just created the object as always.

The blue facets also show up untriangulated in UVmapper although I triangulated the whole object.


Can someone give me a hint?

Try playing around with the materials. I'd have to play around with the actual mesh to be sure but it looks like you might have some of your faces set to "hole."

Yep to what Amber said. Select the mesh, right click, material, select material (hole is the other option)

The problem is, I already gave them a material named wood and it shows up in UVmapper as you can see in the pic. It's the yellow squares.
I never used the hole option on any surface in this mesh :\

I'll attach the mesh so maybe someone finds the fault...

Well, this is very odd! It appears perfectly fine when I load it in Wings. Hmm...

Wings has those inset faces assigned to _hole_ in Outliner (rt+click/select). Just because you mapped them to a specific area in UVMapper, I don't think you actually changed the material assignment.

In Outliner, rt+click/select on _hole_, in Geometry window rt+click/.Material. and choose which material you want assigned to it. If you then rt+click the _hole_ in Outliner you will see it is no longer assigned to your inset faces.

What I wanted to say with the material was that I had already given the facets a material like all other ones, too... However I fixed it somehow; I selected the faces which flashed blue sometimes and deleted them. THey weren't the ones which were blue, they lay over the ones which were blue. I then selected the real blue ones and gave them a normal material.

It worked but I still don't know how I got them in the first place.
But I noticed them in the next mesh, too when I exported it from UVmapper without selecting "export as single group"... I don't know why facets become holes through this but I think it has something to do with it.

Oh, I've had that sort of thing happen once or twice, I should have thought of it. :/ I think that happens when you've got two layers of polygons very close to each other and one of them that's supposed to be hidden behind the other winds up showing through instead. Highly annoying.
