Skin Modifier - Transfer weights between bones.

SyaPed

Subject sums it up basically...is there any way of transferring the influence of one bone ('upperarm') to another ('upperarm_twist')? (leaving 'upperarm' blank) Feels like something that can be done if I knew my way around some of Skin's dusty old tools...

In Maya? Yes ist possible. Lock all influences in the skincluster, except ('upperarm') and ('upperarm_twist'). Now flood (add) the skinweights of upperarm with a value of 1 in the paint weights tool.
All skinweights from upperarm are now on upperarm_twist.

I'll assume you use 3ds max.

Yes you can. Look into skin utilities. You'll find two buttons: "Extract skin data to mesh" and "Import skin data from mesh". The first one makes a mesh object that stores your weights. The other you use after selecting that mesh object and the object you want to transfer weights to (same obj you made your skinData obj from, in this case), then you'll get a dialog with bone lists, where you assign one bone to another; you can just switch up your bones there, or not assign the bone you want gone at all.

In 3ds Max there is no built in method to transfer weighting. But I have a script that does this.

That looks beautiful, thanks Monster

Thanks Zhalktis, good to know there's a native workaround too.
