Locked Nodes

[deathend]

I imported a model from a DXF into Maya (version 7). Things were fine for a while, but it seems that now I'm having an issue with random nodes being locked. For example, when I clean up my unused nodes in the hypershade, Maya gives me an error saying:

// Error: Cannot delete locked node 'blinn1SG'. //

Either that, or when trying to add a blinn to my object it gives me this one:

sets -e -forceElement blinn4SG;
// Warning: Adding all components of 'O_Ring_235x5mm_2Shape' to 'blinn4SG'. //
// Error: Connection not made: 'O_Ring_235x5mm_2Shape.instObjGroups[0]' -> 'set1.dagSetMembers[249]'. Destination is locked. //
// Error: Cannot add the following items to the set since they would break the exclusivity constraint: //

Any ideas? Thanks!

I have no idea why they would be locked but the command to unlock a node is:

lockNode -l 0 objectName;

where objectName is the name of your node. also you can use -l 1 to LOCK a node.

Thanks, yeah - I noticed that command in the help files but is there one for an entire scene? Basically, I'm not sure what nodes are locked...but it seems that randomly as I try to do things I'll run into another locked node. It'd be easier to just unlock all.

But you may delete nodes that are necessary for Maya to function properly (i.e. Lambert1, used by default when you create an object).
You better make a button of an shelf with the coresponding Mel command.

you won't accidentally delete any nodes because Maya doesn't have any locked nodes (it has many READ ONLY nodes, but these are different. i.e. if you lockNode -q lambert1 it returns 0)

so, to unlock EVERYTHING just do a single loop:

CODE
for ($obj in ls)    lockNode -l 0 $obj;

but I would seriously not recommend this all the same... maybe a selection version would be safer:

CODE
for ($obj in ls -sl)    lockNode -l 0 $obj;

this could do with a lot of extra work and protection but what am I? your mother?
