Default Uv projection is messed up...

I have a rather strange problem at the moment, I tried to texture my object and had all my lovely polygons selected. But it didnt go as planned, only a handfull of my polygons were textured, even tho I could see the polygons uv texture editor they turned invincible when mapped(I have no transparancy maps on the object)

Try opening the Attribute Editor for the object.
Under the Render Stats, make sure Double Sided is checked.

You might need to flip the offending UV's faces.

If your running maya 8.5 theres an option in there to colour your UV texture editor, where blue is correctley facing and red is flipped the wrong way.

Run the option gster stated and then do a normals > conform operation. this should get the nomals pointing in the right direction. If not its all by hand I am afraid.

How do I flip the offending uv faces?

And I'm using maya 6.5 so I cant do that. :/

And I think that the polygons that are defect were created by using "create polygon" and then cut.

OK,

Only thing left is to apply a new projection, I would use a cylindlical projection for an object like that.

Try this, select the faces that are not showing the texture, then go to polygons (in the UV texture editor) and there should be an option to flip the UV click that and give it a go.
