Viewport rendering problem - Normalmap seams
I'm trying to learn 3ds max for my internship and I encountered a problem. I tried some of my models in 3ds max to see how it works with materials and stuff but when I used normalmaps my uv seams were completely exposed. The shadow didn't went smoothly over the uv seam like it did in Autodesk Maya. In some way 3ds max doesn't render my normalmap good in my viewport. I think this is strange because it is the same model.
I also noticed some weird black lines over my model which i also didn't have in Maya.
Can somebody please tell me if there is a solution for this? I couldn't find anything on forums and I don't know if it has something to do with drivers, with the way I set up my material or if it has something to do with 3ds max.
All help is appreciated!

in your material editor the normal map should be in a normal bump material- the normal bump material should be set on 100 in the mat ed instead of the default 30
any chance of some images?

Thanks for your reply!
Here are some images of my problem:

Same model in max:

Hope the images are working good :|
I also took a look at the material editor and changed the normal bump material from 30 to 100 but that didn't make a lot of difference.

Play with the settings in the Normal Bump. You should be able to invert the red or green channels or swap them even.
Another thing is that max's gamma & LUT settings might be doing gamma-correction on the normalmaps. So you should turn that off

Thank you very much! The gamma & LUT setting were the problem. I also had to to switch the green channel to get the normals right. I have no seams or weird lines anymore :D
