Marmoset Mirrored UV issue

Ghostman511

Hey PC for some strange reason I'm getting an issue when mirroring my Uvs for a particular part of my model. I'm doing a Tar-21 (http://www.polycount.com/forum/showthread.php?t=121771 )

after scouring the forums for a resolution I found a method of offsetting your mirroed uvs and that worked great for all the other mirrored parts of my gun but for some reason the picatinny rail won't mirror correctly without the normal map becoming inverted and a massive seam cutting it in half. here are some pics.

Please help!!! Any advice would be greatly appreciated!!!

You can try flipping the normals on those red shells. So they turn blue instead of red.

Also, ensure that you have the correct normal settings on your obj export options. I've ran into similar problems like this before.

check to make sure both sides are triangulating correctly

How are you importing to Marmoset? From Max, I need to uncheck "tangents and binormals" when exporting an FBX to avoid mirroring issues.
