Delete Static Channels Help

[mcarange]

Hi yall,
I have been using maya along time and I don't think this has always been the case, but when I delete static channels in maya 2008 the keyframe values are being reset to maya's default values.

For example I keyframe the spec roll off of a shader at 1.0, but have no other keyframes in that channel. When I go to reduce my keyframes by deleteing static channels, maya is changing the value back to its default of 0.7.

Now if it was just one instance that would be easy to fix, but I have alot of static channels and its changing all my shaders back to default values.

Does anyone know is this some preference or something?

You might try a mel script to delete static channels on a selected object; capture the keyed value and set the value back to what it was after maya resets it to it's default value.

Here's a quick and dirty script. It's not perfect so you may have to run it twice. Simply select your objects that you want to remove static channels on and run the script
[codebox]
{
proc dh_deleteStaticChannelsOnSelected()
{
int $keyCount = 0;
string $selObjs[] = ls -sl;
for($obj in $selObjs)
{
// List keyable attributes
string $kAttr[] = listAttr -k $obj;
for($attr in $kAttr)
{
catchQuiet($keyCount = keyframe -q -kc ($obj + "." + $attr));
if($keyCount == 1)
{
float $tempValue = getAttr ($obj + "." + $attr);
cutKey -cl ($obj + "." + $attr);

				setAttr ($obj + "." + $attr) $tempValue;

			}
		}
	}
}
dh\_deleteStaticChannelsOnSelected;

}
[/codebox]

Doug,
thanks for your time and an exellent script ! It works like a charm.

I checked back with previous versions of maya (all the way back to 4.5) and all versions do this. I am surprised I never ran into this problem before. I believe it only occurs when shader attributes are keyed and then keys deleted. I'm not sure why you would want this to happen. Perhaps it is an oversight.

Thanks again.
