Artifacts in model in unity

jose.fuentes

I imported a model made in Maya and Zbrush, and I am having some issues with some sort of artifacting on the model

This is the model with no textures applied, this is where the problem is most apparent 


This is the model with textures  Diffuse, Normal, and Glow Maps Applied



this is the normal map

You rendered a object-space-Normalmap. For unity you will need a tangent-space-Normalmap.

sweet, ill make sure to update that, but what about when i bring in the model with nothing added (the first picture) there is some artifacting going on

Do you have custom vertex-normals applied to the model?

In Maya or Unity? I'm actually not familiar with this

In Maya you can bend the vertex normals. http://wiki.polycount.com/wiki/VertexNormal

This error might also be caused by bad triangulation. Try triangulating the model before exporting from Maya.

That first picture looks like your Normal map is not marked as one in Unity Texture import settings of that file. Have you marked it? 
You can also share the model file, for a much quicker problem identification...
