multiple nurbs surface extra tesselation attribute

[blackbox]

Hi

Is there a way to apply the Vray Nurbs tesselation attributes to multiple nurbs surfaces?

Also is there any updated documentation on the specific attributes

thanks

This is in our 'to do' list.
For now you can use a Mel Script:
A have attached an example, which will apply NURBS Attributes to all selected object except the ones that already have it applied.


global proc vrayCreateNurbsAttributes(int $staticGeom, int $tesselationDepth, float $curvatureThreshold) {
string $selectedNodes[] = `selectedNodes`;
string $nurbsShapes[];
int $i, $j = 0;
for ($i = 0; $i < size($selectedNodes); $i++) {
string $shapes[] = `listRelatives -shapes $selectedNodes[$i]`;
for ($iShape = 0; $iShape < size($shapes); $iShape++) {
string $objType = `objectType $shapes[$iShape]`;
if ($objType == "nurbsSurface") {
$nurbsShapes[$j++] = $shapes[$iShape];
}
}
}

print($nurbsShapes);
print("\n");

for ($i = 0; $i < size($nurbsShapes); $i++) {
string $node = $nurbsShapes[$i];
if (!`attributeQuery -exists -node $node "vrayAsStaticGeom"`) {
addAttr -ln "vrayAsStaticGeom" -at "bool" -dv $staticGeom $node;
}
if (!`attributeQuery -exists -node $node "vrayMaxSubdivDepth"`) {
addAttr -ln "vrayMaxSubdivDepth" -at "long" -dv $tesselationDepth $node;
}
if (!`attributeQuery -exists -node $node "vrayFlatnessCoef"`) {
addAttr -ln "vrayFlatnessCoef" -at "float" -dv $curvatureThreshold $node;
}
}
}

Hi
has this issue been resolved.
I have a lot of Nurbs curve to render and I can't find a way to add the "rendereable" attribute to all my curves.

Could we have the equivalent of object property node for nurbs (curves and surfaces).

Thanks,

Yannick

For curves yes, this has been solved in the latest nightly builds. Select the curves and go to Create > V-Ray > V-Ray Renderable Curve. Still working on the NURBS node.

Best regards,
Vlado

Thanks Vlado.

I'll have look at the nightly
