Maya - File Opening Bug

So I opened my file today and found that it had broken. Some polys we're missing, some points moved, some colours changed...well...just take a look for yourself.

Congratulations, you just got a sneak peak of my Thor model before anyone else! (woohoo....)

You may not be able to tell from the photo but may of the polys and his chest and especially around the mouth are missing, as well as the weird poly that's appeared between the neck and the chest plate.


The cause of this seemed to be that when the file opened it tried to replicate my history (obviously I didn't delete it as often as I should...whoops) and it came up with error such as:
'Warning: Can't perform polySplit49 on selection'
'Warning: Can't perform polyDelEdge18 on selection'
'Warning: Can't perform polySplit50 on selection'
'Warning: Can't perform polySoftEdge21 on selection'


After much googling and trying to get old files to work I was close to giving up and simply repairing the damage that had been done, deleting the history before saving again. Luckily I happened upon a passing comment on a forum that mentioned using the 'dgdirty -a' command which was accompanied by a link on what to do, unfortunately the link was old and broken. I simply typed 'dgdirty -a' without the quotation marks into the MEL script box within Maya and hey presto, good as new.

Hope this helped. Good Luck.

Maya - Interactive Split Tool

Maya has an amazing tool called Interactive Split Tool, it is used to make nice clean cuts across polygons and is great for creating edge loops and fixing topology. Unfortunately it's still new, and as such it's prone to bugs. Sometimes the tool completely refuses to cut, sometimes it cuts but not what you asked it to do.

I would love to offer a fix to this, but I couldn't find one, I still use to very often but I found an alternative to it for the few times it decides it's not going to listen. You can still access the old tool which this tool replaced called the Split Polygon Tool. This can be accessed by going in to object selection mode, holding shift and right-clicking your model, then select Split > Split Polygon Tool. You can then hold Shift while clicking to snap it to points.

I don't think this tool is as nice to use, or as clean, but it does the job when I really need something done and the the Interactive Split Tool is having one of them days.
