Hey guys, this is probably a really easy problem but I'm just jumpin into the mel stuff...


I have :

string $da[]=`ls -sl`;
string $material = `shadingNode -asShader blinn -name godRays`;
string $SG = `sets -renderable true -noSurfaceShader true -empty -name godRaysSG`;
connectAttr -f ( $material + ".outColor" ) ( $SG + ".surfaceShader" );

defaultNavigation -source godRays -destination $da -connectToExisting;


when I run it, it brings up the connection editor asking me what to hook up...
can anyone help me get it so it makes the default connections for all the objects in $da?


thanks

your $da variable is an array.

you need to walk through it using a loop


for ($item in $da)
{
defaultNavigation -source godRays -destination $item -connectToExisting;
}

is the way to do what you want.

cheers

Assuming you've got the objects in an array , e.g. $objects = `ls -sl`;

for ($obj in $objects)
{
setAttr ($obj+".someAttribute") $someValue;
}
