hey, sweet model!! sometimes inverting the green channel in the normal map works for me (also, check your normals before trying anything) good luck

You mean get normal maps to show in your viewport?
In your perspective window go to Renderer->High Quality Rendering

(michael milano) iv tried flipping the green channel in zbrush when making the normal maps but it hasn’t made the normals maps work in maya any sergestions ?

(sadamhu) i can get the normal maps to look ok in the perspective view but when i render the scene the normals are messed up as shown in the maya renders i posted

thanks for looking c and c welcome

hey cardinalsin,

The only ways I know to fix the normal map is

  • check the geometry’s normals, often ‘set to face’ under the normals tab in maya will fix anything weird
  • make sure the bump node in maya is set to ‘tangent space normals’ and not bump and
  • invert the green channel in the map and save it out.

Also, if you have overlapped uvs for symmetry can typically cause problems with the normal map, I typically try not to do it unless needed. good luck hope you figure it out
