Title: UNDO proxy creation: Crash.
Post by: cecofuli on 2015-05-17, 17:51:01
Hello,

often (90%) when I try to "undo" a proxy creation, 3ds max crash.

Clicked few times and it didn't happen. Any guides how to do it? Just create an "empty" proxy, and ctrl+z it?

For example, I'm building my model library and I want to export a 3 trees as a 3 different proxies.
I run the exporter,click "OK" button. Done, great!

But, by default, the exporter is set to "Export to single proxy".
So, I want to undo the last export and change the parameter from  "Export to single proxy" to " Export to a multiple proxies".
If you undo this task, 3ds max crash.

I would guess that the exporter is doing something on nodes (cloning and deleting objects) and when max tries to undo whatever the script did it crashes because the node it is referring to (in the undo buffer) does not exist.
It's a common "mistake" when writing scripts like that and you have to be quite careful to catch all those situations (I personally hate the max undo system with scripts, I still haven't really figured out how it was meant to be used).

But, sometime the undo works (10%) sometimes no.
Yes, I hate UNDO in 3ds max. Sometime I simple move some vertex and, UNDO doesn't work! Unbelievable...
