Normal Map Artifacting

ZBrush Usage Questions
#1

Hello,

I feel like I’m missing a setting or something on this problem. Here goes:

I’m creating a skull with the applications, 3dsmax, Zbrush, Melody ( Nvidia’s Normal Map Generator ), and Photoshop.
I’ve meshed out and UVWunwraped the low poly skull model in 3dsmax and skulpted a high poly version of that model in ZBrush.
Now, the problem I believe lies in a setting from Zbrush or perhaps melody.
When I produce the normal map from Melody using the high poly (zbrush model) and the low
(3dsmax model), yet the normal map is artifacting. Here a picture of the artifacting

Any Ideas?

Thanks

the raycast settings aren’t high enough. The rays are stopping before they find a face.

you can fix by either
A.
making the lowpoly better conform/fit to the highpoly

B.
increasing the raycast settings inside of melody.

Hope that helps.
