Biggest Maya Upgrade "Gotcha's"?

I’m upgrading from Maya 8 to Maya 2011.

Autodesk is more than happy to give me a list of new feature improvements, but I’m curious what people have found in terms of stumbling blocks?

(Right now I’m most worried that people will think Python is a scripting panacea, but also concerned about a lot of rigs and shading setups collapsing)

thanks

I skipped 8.0 and went to 2009, and thence to 2011. Some scripts break, mainly because the UI has some new and some deprecated parameters, but most just work, albeit with odd looking user interfaces. For example, CometSavedWeights broke, but pretty much all the rest of the plug-ins in the package work, and djx posted a fixed version.

Most of the real core gotchas that were released last Spring have been fixed in SP1. Naturally, any plug-ins need recompiled. However I had no issues just importing rigged characters (not a lot of special rendering here, so little info on that).

Since the different versions install in separate locations, there is no impediment to setting both up and copying your work over to 2011 and testing it out. They changed the version of FBX, so going backwards is a lot of extra work; if you avoid the new features you still have some hand-editing of .ma files to export back to 8.

But I’m not sorry I moved.
