problem with the normal map

[ClatoVerata]

Hello,
I´m making a game character, but when I export the normal map from Z-Brush (HiPoly mesh) to 3DsMax (LowPoly mesh) and rendered it have an strange behavior, it makes some strange shadows along de seams. I should had made something wrong, because the normals direction seems to be bad. I Attach a picture for a better understanding.

How can I solve this? I don´t Know in which point I had made a mistake.

Thanks for your help.

flip green chanel. then before exporting in zbrush there is a seem overpaint option in texture menu. use it to overpaint a few pixels to hide the seems. and in max there is a blur optionin texture winow in the coordinates rolldown there are blur and blur offset - set blur to 0.01.

thats not the channels, its 3d max gamma settings, when you import it into max make sure to "overide gamma exposure".

wait, il post a pic, just a sec

Thanks very much for your answers. I´ve been looking at those options. The green channel was already flipped, but I havent found the "seem overpanit option" and the way to paint with it on the normal map in ZB.
I also changed the gamma settings in the Max preferences. I´ll make render to look the behavior and show you.

Thanks.

You may wanna try using xnormal. Its what I use and I don't seem to run into these kinds of problems.

In the new model I´m working on I´ll try Xnormal.
Thanks.
