Grey border on edges of my color texture

[mitchell-snary]

I am getting a thin grey line on the top and bottom edges of the texture image that I am using for the color of my material. Outside of maya the image has no grey borders. I have tried to import the image as .iff, .tga, and .tif file formats, and all formats import with these grey lines at the top and bottom edges of the image. If I increase the resoulution in the texture file attributes (under "Extra"), the grey border lines shrink.

I am using this image to texture one surface of a stiched character. I am fairly confident that it has nothing to do with the geometry, but if any one has any insight it would be greatly appreciated.

Hi,

You may want to check off the Wrap U and Wrap V of the 2d placement node of your texture, or set the texture filter to off (but I think the wrapU & V is the cause of your troubles..)

Hope this helps

Hi, Thanks Emanuel. But I have checked off the Wrap U (it only occurs in the U direction) in on the 2d placement node. This does make the grey line smaller, but it is still there. I also tried turning off the filter but that made no difference. I have posted some images of the problem at :

Both of these renders are with the Wrap U off. The top render is a standard render. The bottom is a Hardware Render, where you can see the problem more clearly. There are patches above the grey line (just under the arm pits) where other textures are working seamlessly, as you can see.

Hi,

Well, the mapped object is one surface or a trim or something (but multiple objects)?

It seems (to me) that its a (bad?) edge of your model, but I can't tell you more.

If you want, send me the scene (just with the object AND its texture fiel (jpg)), I'll try to have a look on it, because it's (sorry) hard to tell you what goes wrong with your obejct/ texture...

just try paint texture tool on edge of brand new plane (nurbs or poly) and you'll see thin stripe of color on oposite side..

alpha channels in images can sometimes be the cause of this error. If you have alpha, save it as a seperate image, and use hypershade to link it to the shader as a seperate FILE node.
