View Full Version : Wrap Deformers???
08-03-2007, 06:56 PM
Currently using a wrap deformer on a few characters and a problem keeps occuring with them. The problem are vertices spiking out of the wrap mesh. Both meshes are identicle in build so I'm wondering why is it occuring and the best way to fix it. I hope someone can assist with this.

You'll need to adjust the tolerance of the wrap deformer to best represent the density of your mesh. The smaller the value the tolerance is, the more precise your wire deformer will be but the more your performance will suffer.

yes... Shawn already said it... you should check your settings on the wrap deformer - lower is better, but slower :)

global proc sm_wrapSetDistance ()
string $selected = `ls -sl`;
for ($select in $selected)
string $shape = `listRelatives -c $select`;
string $wraps = `listConnections -type wrap $shape`;
for ($wrap in $wraps)
setAttr ($wrap + ".maxDistance") .1;
print "All selected wraps set to .1\n";
Just a quick snippet of code, feel free to adjust the values for the maxDistance attribute in the script to what you require. I use 0.1 for most of my stuff so give that a shot.

I normally keep the wrap deformer on its default tolerances. Nothing seems to happen when I lower the Max Distance to .1. I still have that spike happening regardless of what I do with the controls. I'm posting a picture of the spikage up, so you can see what I'm talking about. These vertices only shoot out at a specific point and once past that point they go back to normal. Those numbers from start to end -.57 thru -.607 on the eyelid controls. Before and after those numbers the wrap works fine. I want to start thinking that it is the model itself or the way that it was modeled. I really appriciate your assistance.

Just a quick thought but go into your Edit Membership tool and check to see if that vertex is fully attached to everything. Strays like that can sometimes be a bad vertex that slips outside the given influence. If your distance attribute isn't helping I'd say maybe check that, or also look into what measurement units you are using in your settings as Maya does have a limit of how far an object can travel before it begins to choke on the matrices. That doesn't happen until many thousands of units though.
