Textures/UV's not working for some objects

I'm using exactly the same procedure for my objects, but some work and others don't.

In Hypershade, I created a lambert, connected a FILE node to its COLOR and used a targa image as the file. This is the network I'm using for all my objects however the strangest thing is that it works for some and not for others.

When I use the same non-working shader network onto another object that was working with another shader network, it works. Similarly, if I use a tested working shader network onto the non-working objects, it doesn't work. I might be wrong but because of this I feel it's the object that is the problem.

Please help! I have my student project due in a few weeks. Thanks in advance.

Best to show a screen shot of whats happening but it might be your norms try turning in your panel/lighting/two sided light off, if the norms are wrong should show as black.........dave

Many thanks for the reply, Dave. I forgot to mention that I tried reversing the normals as well. I tried again just now while turning 2 sided lighting off as you suggested and it's the same (please see attachment). Flat color, no texture.

(When I reverse normals only then does it turn black indicating the normals were originally the right side up)

I also tried loading it up in both windows and mac. Same problem.

It works when I recreate the object from scratch using similar UV's, the same shader network and the same image file. I guess this means it's definitely a problem with the object itself. However there are dozens of objects that are not working and I don't have enough time to sit and recreate them all. (The deadline looms)

Thanks again. I appreciate your help.

Have a look in your UV editor to see if your UVs are flipped, click on highlighted button (blue good, red flipped).............dave

Is it possible to upload one of the problem objects?

UV map and object file are attached.

Thanks all for your time.

They are not UVed correctly, for a simply thing like this just use auto map that should fix it...............dave

Edit:one of the parts does not have any UVs that I can see

Hi, could you tell me where I went wrong. I used an automatic planar map.

The only part that was meant to be UV'd was at the front. The back side is not UV'd (yet).

Could be that you UVed first then did a extrude?..............dave

Edit:planer will only do 1 side projection

I started UV'ing after completing the entire model... so no extrusions after the fact. Also tried with other objects. I just need the UV projections on one side (the front) hence the planer mapping. As you said it's a very simple object with a simple automatic UV so I don't see where I'm going wrong.

Update! I exported the problem object as an .obj with `materials`, `smoothing`, and `normals` set to `off`. Imported the obj back into the scene and it worked! Just thought I'd give you the heads up.
