Possible To "protect" Certain Nodes In The History From Deletion?

[rgkovach]

Is there a flag or attribute which can prevent Maya from following through with a call to Delete History?

In other words, could I attach some flag to a polyColorMod node such that if a user were to try to delete history, they would get a warning first that doing so would delete something flagged as important?

Thanks.

use lockNode on the nodes of your choice.

Thanks for the tip, here is what i found...

if I have a pSphere with a blendColorSets node and two polyColorMods and I lock those 3 nodes, select the sphere and Delete History, the nodes are saved from deletion, but their connection to the pSphere is lost.

If i lock the pSphere and try to Delete History, then the entire history is preserved like you described...
So it looks like I'm gonna want to lock the shapes, instead of my original thought, which had me thinking of protect individual noes in the graph.

you could even override the delete-command to catch such a case and offer a dialog or whatever.. :]

You can also lock the attribute connections. (however maya can force everything no matter what)

But really theres no way you can make it so that user cant do this, at the end of the day maya user is the king and he will have final sayso no matter how much you think yous should have sayso.

You can also make a scribtjub that reconnects it.

So you can only make safeguards if the user thinks your safeguards are okay.

The real question is why would a user go and delete history if they dont have a good reason to do so? Hence, if they have a good reason then they will do it no matter what your safeguards are.

So the general answer is no you cant prevent user form doing anything, they can always unprevent you.

Luckily for me, my users are not very savvy!

They will surprise you one day. Theres nothing so certain than the fact that someone will eventually undermine your system. This is why i think making copy protections is a waste of time. Mainly because the amount of people doing the undermining allways do it faster then the protector, and they dont even do it conciously it will happen automatically. Its one fundamental fact of human nature.

If it can be broken it will, if it can be circumvented it will, if advantage can be gained by doing anything it will be done sooner or later. Usually sooner than one thinks.
