collision iterations vs smoothing iterations

I am never quite sure of the difference between collision and smoothing iterations.

Whenever I am trying to fit an item of clothing to a figure, I tend to adjust both until I get a toght fit. But I am not really sure what I am doing and would like to dial more responsibly ;)

what do they each do exactly? is one better for clothes fitting than the other? (I think with some coforming clothing you first have to apply a smoothing modifier or set smoothing modifer base - again, I am unsure of the difference)

Thanks

    Smoothing does that - it smooths out bumps and lumps in the model. Collision adjusts the model to push it outside any of the mesh it is colliding with. Both are iterative processes - a small change is made, then the process is repeated. Collision itrations should not affect any areas that are not cutting into the collision target, smoothing will affect the whole mesh, but they are doing different things anyway.

    thanks. so there is no point adjusting collisions to get a better garment fit? It's all done with smoothing?

    Collisions will help with pokethrough, smoothing can be an issue as it can kill the morphs you may also be using to help with the fit.

    So in the simulate tab under collision iterations if you increase that number it will do what? Collision iterations (per subframe)
