Maya Scripts

applyClothPresetToMultiple.mel was used in the gif.

 Some MEL and Python scripts to improve daily tasks in Maya.

sortByPolyCount.py
Add to maya shelf, make a selection, click.
Console will print the name and poly counts of the heaviest objects.
You can then easily isolate the selection (ctrl+1), or keep the selection in the layer it creates.

def sortByPolyCount(top, layer):
    objects = cmds.ls( selection=True )
    tri_list = {}
        
    for object in objects:
        cmds.select(object)
        tri_count = cmds.polyEvaluate( t=True )
        tri_list[object] = tri_count
    
    sorted_names = sorted(tri_list, key=tri_list.__getitem__, reverse=True)
    for name in sorted_names[:top]:
        print("{} : {}".format(name, tri_list[name]))
    
    if(layer):
        cmds.select(sorted_names[:top])
        cmds.createDisplayLayer(name='top')
    else:
        cmds.select(sorted_names[:top])
    
    return tri_list

sortByPolyCount(5, True)
 

applyClothPresetToMultiple.mel
Add to maya shelf, make a selection, click.
This script will apply a saved nCloth preset to all selected cloths.
You will need to replace “inflate1” in the code to the name of your preset.

//select all cloths and run
//to apply same preset to all 

string $cloths[] = `ls -sl`;

for ($cloth in $cloths){
    select $cloth;
    string $clothShape[] = `listRelatives -s `;
    print $clothShape[0];
    select -r $clothShape[0];
    applyPresetToNode $clothShape[0] "" "" "inflate1" 1;
    
    //dynExpression -s ($clothShape[0]+".pumpRate = rand(0.5, 1.25);") -rbd $clothShape[0];
}
 

setAiOpaqueMultiple.py
Add to maya shelf, make a selection, click.
This script will set the ‘aiOpaque’ property to false on all selected.
This is useful when you have several objects that all need to be rendered as transparent in Arnold.

import maya.cmds as cmds

objects = cmds.ls( selection=True )
for object in objects:
    cmds.setAttr(object + ".aiOpaque", 0)
 

seanSplicer.mel
Add to maya shelf, click.
This script will slice n’ dice models. 

// create a GUI
            window -title "Sean Splicer" -menuBar true -width 100;
            
            // add a help menu
