3DSMAX Maxscript Undo

OccultMonk

When using Maxscript 'Undo On( ... )' 3DSMAX does not see the whole block as one big undo. When for example I use loops within the 'Undo on' block and change object properties these changes are seen as separate Undo entries. When I use Undo, a lot of these changes are stored separately, and I have to undo many times to undo everything in, what should be, one Undo block. Isn't there a way to save all changes in one Undo block as one undo instead of multiple entries?

Mind posting up the code if possible? If i remember correctly you can undo a maxscript. I generally try and have undo off if possible.

Instead of UNDO ON use:

theHold.Begin()
-- your code here
theHold.Accept "Name for the Undo record"

To be sure that there is no other theHold running you can check it before to use your theHold.Begin()
