Hello guys!
I was doing some research and couldn't find a decent answer to simulate underskin.
I recall a long time ago there was a really nice plugin called PolyFit thar let you deform one object with another.
How coudl you achieve that: deforming one object with another?
I am looking for something interactive, not a two (or more) steps solution. I want it to be adjustable while animating.

Any suggestions?

Thanks!!

Thats cos there isnt a decent answer in LW. Polyfit was a modeler tool, so you can forget that. For animation, the only things you can do with any real measure of success is to use effectors, or build some kind of wrap in nodes.

There were 2 plugins: pointfit and polyfit. I'd bet that PolyFit was for layout (I'm like 90%).
I'm sure there should be a way with nodes but I lack the knowledge to do it that way.

I am aware that this is no every day requirement, but being 2017 you could expect to have some tools to address this. But let me stop myself here, I don't want to start another rant, there are like 236 other posts to do that.

Yes you're right, polyfit was the layout one.

Still it's yonks old, and not that good, and also, nope, no real tools to address it. Effectors or nodes, that's pretty much your lot. There are other methods you can muddle around with, ofc, but they're either so unwieldy as to be useless, or the results are just rubbish.

Your diplomacy is appreciated.

for realtime, try RayCast

YES! I was jus playing with raycast but wasn't getting it right. This looks exactly like what I was looking for.
Will see later how it behaves with more complex objects.
Thank you so much erikals!

Happy 2 help   :)

haven't tested it fully "in production" though

another example, just adding a weightmap

subnote, stole this source from the LightWave 11.6 content folder.

note. it will not work for complex areas where the joint twists in 3 axis (H,P,B) like the shoulder, only option for muscles for the shoulder area is using dynamics.
(or a super-quadrupel-complex shoulder rig) this is not a LightWave specific limitation though, this goes for all 3D apps.

Option >

Semi-Realtime, this SoftFX simulates >Superfast<
definitely something to consider.

I saw this video a few days ago but this is more suitable to simulate jiggling. I am looking for something like the skin sliding over the scapula. Your first finding seems to be the route to go.
