Select object one by one and do some operation on it?

[Anonymous]

I'm not familiar with MEL but i'm sure this is pretty easy and can takes me way less time than doing by hand this.

In my case I would select one object and do a combine on it (polyUnite). Then selecting the next one and so on...

The problem is that when I use MEL it select all the objects. Can you help me making it easier ?

Thank you !

you cant combine on just 1 object, so im abit confused.
can you provide an example?

as for looping and performing actions you typically use

string $mySel[] = `ls -sl` ;
for($sel in $mySel){
   //do command on $sel
}

To be more precise my objects are transform objects that have multiples shapes. (It's a CAD files I'm using).
To clean the multiple shapes into 1 shape and 1 object I need to combine it.
But I wish to keep the transform separate to each other so I don't combine 2 objects, only the shapes.

It results an error :

string $mySel[] = `ls -sl` ;
for($sel in $mySel){
polyUnite -ch 1 -mergeUVSets 1 $sel
};
// Error: }; // 
// Error: Syntax error // 
// Error:  // 
// Error: Syntax error //

this should work then.

string $mySel[] = `ls -sl` ;
for($sel in $mySel){
    // get shapes of object
    string $children[] = `listRelatives -s -fullPath $sel` ;
    // combine and store new objects
    string $newObject[] = `polyUnite -ch 1 -mergeUVSets 1 $children` ;
    // delete old transform node and rename new to old
    delete $sel ;
    rename $newObject $sel ;
}

Thank you for the tip !
It works wonderfully !

But the mesh generated miss something that I need to set a new shading group otherwise I only see the edges when I higlight it.

I seems like that it happen when I use the rename script. So I get rid over this part 🙂

Thank you so much 🙂

Can I ignore error message that make the script stops ? It happens because some of my objects don't have multiple shapes in it so it fails to combine and result as an error.
