3ds max seam issue

barnesy

Hey Polycount,



I am having an issue with seams of the head at the moment. For some reason half of the face is much darker and there is a annoying bright chunk to the right of the seam.

I have tried resetting the x form, adding a normals modifier, checked the directions of the normals in edit mesh, re imported/exported, offset the UV's, deleting half of it and re mirrored/welded the model :S

Is there any other techniques that I could try?

Thanks

What Max version? 2013 and 2014 are a bit troublesome.

Is that how it looks in the realistic viewport? How does it look when its rendered?

What does it look like if you turn off the diffuse and normal map?

What does it look like if you turn off Gamma correction?
(Main menu > Rendering > Gamma/LUT Settings > Disable)

If a normal map is being gamma corrected it will throw the colors/calculations off and give you a seam. In older versions of max it was off by default, in newer they turned it on by default which throws normal maps into chaos because it gamma corrects them and alters the colors, unless you counteract the gamma on a per map basis...

If that's the case either leave off gamma correction or re-assign your normal map and in the file explorer window use the Gamma settings to counteract the gamma correction. It's next to "devices", most people don't realize that is where you have to go to set the gamma settings and only is accessible when picking the map, which is kind of retarded on autodesk's part. They should have put that in with all of the other settings where it won't be so easy to miss.

Damm I forgot to mention the version again!

I am using 2012 which is working much better than the 2013 version. I might switch back permanently switch back to 2012.

Thanks Mark, I turned the Gamma on, then back off amd restarted max which has sorted it out

I would have never thought of that!
