Index Card - Strange lines in render

rabscuttle

I'm creating an index card and I'm getting some thin grey lines in the center of the image in my render. I double-checked my color map and my bump and it's not in those image files. Maybe it's something in the geo? Here's my mesh and my render. Any advice would be helpful. Thanks, everyone.

I'm no expert, but have you tried applying the sub-D so you can manually check the generated geo/Uvs? That seam is right where the central split would probably end up.

Hi.This can be because of the missing of the padding, or because of the mipmapping.

Check the unwrapped UV ?
