Hi John,
I think the problem here is with the AEtemplate script that handles the
display of the compound's child attributes.
Notice that if you create your 'blend' attribute outside a compound, as a
top-level attribute, it'll show up ok in the AE. But you've already
discovered that there is nothing wrong with your node description....
Open the script /autodesk/MayaX/scripts/AETemplates/AEnewCompound.mel
Look at the enumeration of possible child attribute types after line 130
(immediately after $childType = `getAttr -type $childPlug`;) and you'll see
that the attribute type 'double' is missing from the list.
You have two choices:
1) either modify this script to include an option for 'double', like this:
else if( $childType == "double" )
{
// we use AEnewFloat() because there is no AEnewDouble()
string $childCtrl = AEnewFloat($childPlug,
$childAttrNice, $changedCommand);
}
2) or change your 'blend' attribute to a float instead of a double.
I hope that helps....(am not in front of Maya so haven't tested this :) )
cheers,
Owen
