explicitly name a wrap deformer

How do you explicitly name a wrap deformer, and more importantly the wrap deformer base?

and if you can't, how do you grab the wrap deformer base for manipulation?

wrap = mel.eval('doWrapArgList "7"{"1","0","1","2","1","0","0"};')

I got this, but not much else.

It looks like you copied the code you saw in the scriptEditor after manually applying a wrap; specifically, the doWrapArgList command calls another internal script passing along options from the option window.

To find out how to properly apply a wrap deformer, find the MEL script in /Installation Directory/Maya201x/scripts/other/ that performs the wrap (e.g. by running 'whatIs "doWrapArgList"').

I believe there is no built-in command to bind an object by a wrap deformer, but you can always go the hard route and just create the appropriate nodes ('wrap') and connect the right attributes yourself.

create my own wrap huh?

Oi. That was a level higher up then I originally expected, but here goes nothing I suppose.

Allright. Time to dive into the messy mel ness I suppose. I notice that Maya's wrap script was written in 99', have there been any more recent advances to the tech, something more ah... Pythonic I could reference?

Almost everything you can access via Maya's UI is written in MEL. And MEL can be translated almost verbatim to functional Python.

From what I recall (can't access Maya right now), applying a wrap deformer just involves duplicating (and hiding) an instance of the influence object, connecting that to a wrap node, and connecting the wrap node to the target object.

A quick google tells me you should be looking at a file called CreateWrap.mel (or a file that contains a function with that name).

yup, poking around in that file now.

Mel isn't hard. It's just dirty, and the syntax makes my brain hurt since I've been in python so long.

And CreateWrap.mel was written in 99'. I just was wondering if there were any newer wrap paradigms that have emerged since then.

I certainly have seen a couple in hunting this down, though they're written in C++ which is out of my league currently.

Well there may certainly be third party plugins that offer similar functionality (deforming based on influence geometry), you'll just have to search.

But if all you're looking to do is include a wrap deformer via Python script, then just copy the essential steps you find in the related MEL files.

The SOuP retarget node is possibly of interest to you


Its incorrectly titled as "smooth node", but its the one with the 2 characters wearing the green and yellow shirts with blue pants.
