Drawing overrides

[rokandic]

You must use -lock flag to lock/unlock the attribute. In your case:

setAttr -lock 0 curveShape2.overrideColor;

[lifire]

Well, even though I'm slightly embarassed to admit having that part wrong, the correct syntax still does not actually unlock the drawing override. When I execute it, it seems all is well, then I try to change the color in the attribute editor and... same error.

I figured it might be because the controller curve is a child to a null group for alignment purposes and I have to unlock that group as well, but that didn't work either. Weird.

[rokandic]

Two things to check:
1. Is it a curve from a referenced file?
2. Is something connected to that attribute and thus cannot be changed?

[lifire]

Hmmm.... I don't see that the override is connected to anything, at least I did not intentionally connect it. So unless something in my scene inadvertently connected all the overrides to something for all the curves currently controlling my character...

As for the curves, they have not been referenced or anything.

You probably have it on a layer. Once there, you can't override as far as I know.

[lifire]

As much as I thought 100% that removing it from a layer would work, sadly it did not. Oh well, I guess I'll just make 2 layers and change their display colors.

I have a script that can over ride the colors of a given selection of nodes. If the node is on a layer the layer is disconnected from the colorOverride and change to a given color.

/*
colorOverride
Disconnects the overrideColor from the layer if available and applies the color given
Accepts 2 arguements:
$list[] - Nodes that will have their color changed. Transform nodes will be evaluated
to color a shape node if available. `ls -sl` can be used to color the selection
$color - values are based of Colors preference, index 1. (Window -> Settings/Preferences -> Colors...Tab(Active))
examples: 6 blue, 13 Red, 14 Green, 17 Yellow

//This script is desiged to change the colorover fuction to a given color
global proc colorOverride (string $list[], int $color){
string $shape[], $layer[], $colorNode;

for ($node in $list){
//determine shape node
$shape = `listRelatives -f -s $node`;
if (size($shape) == 0){
//transform only
$colorNode = $node;
}else{
//shape node
$colorNode = $shape[0];
}
//determine layer
$layer = `listConnections -t displayLayer $colorNode`;
//disconnect layer if exists
if (size($layer) != 0)
disconnectAttr ($layer[0] + ".drawInfo") ($colorNode + ".drawOverride");
setAttr ($colorNode + ".overrideEnabled") 1;
setAttr ($colorNode + ".overrideColor") $color;
}
print "Color override complete.";
}

Wow, thanks for that! I tried a different color override script and it didn't work. I just tried this and it worked. Now I'm just trying to figure out how and why it works, considering my curves are no longer in a layer. Yet it doesn't work if I simply enable overrides in the attribute editor...?
