You create a bone structure in each breast in blender, then you weight paint that rigged part, and then import in unreal with some physics asset load in. Of course with some tedious tweaking

that's a huge jump from basic bones to physics...

Looks like physics objects are driving a series of deformation bones. There are possibly morph targets as well.

It's basic spring and dashpot physics. Unreal engines scripting system has raycasts and collisions I take it?
You set up collision detection for your bone and you translate it according to these concepts:

https://en.wikipedia.org/wiki/Hooke%27s_law
https://en.wikipedia.org/wiki/Dashpot

The springs obey hooks law and attempt to return titty to original position by adding torsional forces according to how stiff you made your spring.
You use a dashpot equation to cancel out that motion simulating the energy dissipating thru the tissue, set it to a value that matches the spring so it looks like a fleshy jiggle.

Game physics is just physics. If you know how to program/script and you know regular physics you know your highschool physics (classical mechanics) you can do game physics.

Thanks for your reply, but I wasn't asking about the basic idea, of course I know what physics is. I'm specifically talking about getting it to look and behave like that example, and specifically in Unreal Engine.
Practical example and specific workflow in UE, not explanation of basic concepts.

Yeah but that is how you do stuff like this in game engines. You write a script that does the custom behavior you wanna run.
In this case set up a physics joint for a boob.

In Unity, which is what I use, I write a .cs script using unitys built in 'raycast cast' class to detect collisions
take the delta o work out the collision forces, convert it into newton and write a custom algorithm that animates the affected bones
according to the energy stored in the springs.

UE does it that way as well. Especially via blueprints where you can extract properties out of an actor.

That's being pendantic. It doesn't have a scripting language packaged by default, but OP meant programming. You could program those solutions in blueprints and/or c++ if you wanted to. It's not magic.

I'm pretty sure the dev posted here once. There was a thread called something like "how do you rig for these deformations" with some catgirl ass that went off topic and started talking about tits.

>>858663
Stop being a lazy retard. If you understand how physics assets in UE work you can work it out. Tit physics is no different to any other kind of physics, you just add bones where you want things to move, weight paint them, then tweak the constraint values in UE until it looks right.

You claim that it has tools, but you don't know what they are because you're well aware that it doesn't. Otherwise, you wouldn't be asking that question in the first place.

You could try something like how those grass or snow shaders work, where you blend between two textures based off of texture data stored in a 3rd, lower res texture. It shouldn't be too hard, and you could just use a colliders collisions to "paint" the 3rd texture for blending. I'm not good with shader code, though.

its a mesh morph that gets activated when the respective outfit is equipped. Along with a set of modifications to the physics settings to simulate firm or loose areas.

For a realtime simulation this is by far the best thing I have seen, and I have seen quite a bit.
