Rendered Normal map has artifacts

JostVice

The problem starts in 3Dmax, I have rendered to texture the highpoly model to my lowpoly model, and I get these weird artifacts (Look at the metal, top right) I've been told that they are bugs of using mirror in the UV of the axe:



I though my UV was correct at first place, so my questions are anyone knows what is wrong with my normal map, could it be the UV? is my UVmap Correct?

And well, The problem happens too when baking the texture in zbrush too.

Thanks

It could be the UVs or the projection. Post a screenshot of the model.

Have you reset x-forms on the low-poly model?

It is difficult to figure out what is happening there without more information.

edit: do you have overlapping UVs? Your post makes it sound like you do, but the UVs themselves look like they don't have overlaps.

Oh well, sorry. If you need any more information, tell me what you need!

And i'm going to try the xform now

Here is the lowpoly model.


192 polies

here is the cage, its just the original mesh (reset) with a push



Here is the subdivided sculpted, it sits on 119.424 polies

His axe UVs were not relaxed correctly. I had a try at his model before this thread was opened, and the parts having artifacts are reversed or flipped in the UV space.

When I remade the UVs of the axe from scratch problems were gone.
