How do you deal with items that need multple collision objects?

I'm using The Short Order Cook outfit on a character, and am having issues with pokethrough, Took care a a bunch of them with Poke-Away and Fit control, but am having issues with the apron in some animations... If I set the Apron to colide with Genesis, it makes a big mess with both the shirt and the pants. If I set it to colide with the shirt, I have problems with it passing through the pants, and same when I set it to colide with the pants... So when you have a item that is going to colide with multiple other items, what's the best course of action? invisible body suit? something else? I can work it out on a single frame render, but for animation, it's not working so hot at the moment.

That's a very good question. I'm inclined to go with invisible body suits.

What you might try, off the top of my head:

Pants -> invisible suit A collides with it -> shirt collides with invisible suit A -> invisible suit B collides with either suit A or shirt -> apron collides with suit B.

The problem, with collision, is that I think pants/shirts often lack any information on areas they don't cover, so you loose the onion layers.

Another thing to consider is having fit and collision set to different targets.

If you're just doing a single frame and need to get it to work, perhaps explore [Create > New D-former] as a way of widening / shrinking certain mesh areas of the clothing. If you're unfamiliar with the feature, it's essentially a way to create custom "morphs" for any geometry. Check http://docs.daz3d.com/doku.php/artzone/pub/software/dform/dform_anatomy for more info on how to get it working.

Edit: Derr, you said you were working on an animation. Regardless, you can animate the deform strength & position just like any slider, so that is still a viable approach, especially if it's just coaxing the meshes close enough to have the Smoothing modifiers play nice.
