Maya & zbrush displace ( Urgent)

[hakanpersson]

Did you import the meshes from zb before rendereing, or just a displacement along with the original mesh? You should grab the one from zb, since its softened after being tesselated by zb.

In case you already knew all that, this script is from Scott Spencer aswell, to solve issued with maya 2008 (or mental ray 3.6 more like it) and the cmc tesselation method. Havent tried if it, but thats basically what everyone recommends whenever somethings doesnt render accurate.


//COPY THE SCRIPT FROM HERE
// mental ray Subdivision Approximation script
// by scott spencer
//scott@scottspencer.com (http://forums.cgsociety.org/)
//converts all subdivision approximation nodes in the scene from CCMesh to subdivision surface as well as sets the option
// to use maya style alpha detection
optionVar -iv "miUseMayaAlphaDetection" 1 -sv 1 1; //sets maya style alpha detection - mthe same as
// checking the Alpha is Luminance box in the file node but this works for all displacements in the scene
string $selected[] = `ls -type mentalraySubdivApprox`; // selects each subdivision approximation node in the scene and adds to an arry
int $size = `size ($selected)`; // creates the counter variable
for ($a=0;$a<$size;$a++) //increments thru the array
{//beginning of loop
string $name = $selected[$a]; // this variable accesses each element of select using $a as an index
addAttr -ln "miExportCCMesh" -at bool $selected[$a];
}
//END OF SCRIPT
