View Full Version : Various Approx. statements at a time

05 May 2003, 09:29 AM
I want to control NURBS Tesellation through Approximation editor but it isn´t able to apply more than one at a time.
I tried to assign the same criteria for two or more objects at a time using MEL but when I assign one through the Aproximation editor no MEL scripting appears in the Script editor, I check if "echo all commands" is ON and it is, but no MEL appears either, is there any MEL command to apply an approximation criteria for two or more objects at a time?

Thank´s in advance!

hello joie, i`m larry from

try it with the attribute spread sheet

Qué pacha Larry...

Hi, But..., does Atribute spread sheet contain MR ray attributes like those?, mmm, I think not, but I need to check it.

This annoys me since I don´t know why some kind of MR Attributes doesn´t appear in script editor, that´s all.

Thank´s anyway

well, this is a basical script to change the attributes in thenurbs you have selected

at this time you can only set the u, v and sharp values

y must do a interface for easy use

the sintas is

fvTeselationMental uValue vValue sharpValue

// mel script to set the teselation of the nurbs surfaces in mental ray
// Fernando Vizoso Martinez
// 05-12-2003
// is a basic script for select the surfaceApprox nodes

//to do
// an interface to control all the attributes of the node

global proc fvTeselationMental( float $u, float $v,float $sharp)
string $lista[];
$lista=`ls -sl `;
string $elemento;
string $listaMental[];
int $existe;
int $conectado;
string $listaTemp[];
string $shapes[];
for ($elemento in $lista)
$shapes=`pickWalk -d down $elemento`;
print ($elemento+"\n");
$existe=`attributeQuery -node $elemento -ex miSurfaceApprox`;
print $existe;
if ($existe==1)
$listaTemp=`listConnections ($elemento+".miSurfaceApprox")`;
print ($listaTemp[0]+"\n");
for ($elemento in $listaMental)
setAttr ($elemento+".uSubdivisions") $u;
setAttr ($elemento+".vSubdivisions") $v;
setAttr ($elemento+".sharp") $sharp;

change it to work as you want

WOW, you´re amazing!, surely you have to put this MEL in the MAYA FAQ section in here, people will thank you for a lifetime

Just curious..., how did you get that MR mel syntax?, just curious...
