Excluding nextFrame (prev) & nextKey (prev) from undo

[InAction]

Here's a sample script which I use on meshes exported from UE3. (UVs/vertices are all split so you must recombine everything) This easily crashes Maya because the undo queue fills up the memory, the undo part should be easy to understand. :)

// Query current Undo settings
int $inf = `undoInfo -q -infinity`; // Store Undo Infinity setting
int $length = `undoInfo -q -length`; // Store Undo Queue length

undoInfo -swf 0; // Turn off Undo queue


//////// Your script here ///////////
string $selection[] = `ls -selection -tr`;
string $object;
for($object in $selection){
polyMergeVertex -d 0.01 -am 1 -ch 0 $object;
polyMergeUV -d 0.01 -ch 0 $object;
}
/////////////////////////////////////////////

// Turn on the queue again
undoInfo -swf 1;

// If our queue was infinite before, turn it back to infinity
if($inf == 1)
undoInfo -infinity 1;

// Otherwise have it off and set our queue length
else undoInfo -infinity 0 -length $length;

Edit*
Just read the thread on the other forum, maybe this isn't your solution after all. :hmm:
