Viewport colors problem...a lot of pink

[evanerichards]

So I have a model that I am working on that up until two days ago displayed fine in the viewport. Now all of a sudden all the colors are messed up.
In this first picture, all those panels are panes of glass. There is nothing pink about them. And yet they are pink and some have even started to turn red.


In this second picture the green material on the roof should be the same as the material on the building. And yet the building is white (it was pink until an hour or so ago) and the windows are pink (with the exception of the one pane even though it is an exact duplicate of the other windows. Also the flags on the building are just black even though they have photos mapped in the diffuse slot.


Any idea whats going on?
I should mention everything seems to render out properly this is just a viewport issue.

Which Maya version is this? Do you use Viewport 2.0?

Best regards,

This is maya 2012.
I do not use viewport 2.0 but the regular viewport has been working all along up until two days ago. And its halfway working because it is displaying the proper colors on some objects but not on others.

If it's not an issue, the fastest way to find the problem is to send us the problematic scene.

[evanerichards]

Ok. I'll send you the scene.
Thanks

There seems to be some kind of materialInfo mess in your scene. I don't know the reason. Your materialInfo expects a texture from some materials, but they don't provide it. To fix this, find the problematic shading groups. And type:
listConnections blinn12SG.message
One of the connections will point to a materialInfo node. Select it - something like:
select materialInfo26
There will be a texture attribute that points to a material. You can manually disconnect it with something like:
disconnectAttr FenwayGreen.message materialInfo26.texture[0];

That is tremendous. Thanks so much. I appreciate your expertise. Do you know how to keep this from happening in the future?

[ivaylo.ivanov]

No idea how this could happen... I see it for the first time.
