Find out how long the animator you admire has been doing what they do. Do it for that long, and don't let them sell you an easy solution. If you don't care enough to put in the hours, find something you care about where you will put in the time.

you want to use a volume based cloth sim that drives deformation on your base mesh. To make it "realistic" is to obsess over the settings to the most minute detail for the rest of your life.

The Cloth simulator in Blender does work but it's hard to set up because it's scale-sensitive and because of the limits that are hard coded for the parameter sliders, your model has to use centimeters as a unit, which is typical Blender bullshit.
Self-collisions and internal springs barely work at all, which is typical Blender quality.
Blender 4.0 Alpha is already available if you want it:
https://builder.blender.org/download/daily/
and they've fixed zero bugs around physics because the whole module, instead of using Bullet or some other established physics library, two russian guys went in and wrote the entire thing from scratch, so they're the only ones who knows how it works, which is typical Blender procedure.

>> No.952392

>>952379
I've made this >>946599 and >>949959 and several other tests a while ago. They're scattered all over the board and some got lost.
The first one has self-collisions, the second one has internal springs. But I was never able to make both of those features work together reliably.

There are limitations and I don't think anybody has made a good video tutorial yet. My advice is to get a low poly human figure, roughly rig it, add the cloth modifier and just play with it.
One of the simulation parameters is related to the average edge length of the mesh, which is a problem. If you have very fine details such as fingernail grooves, you've got to get rid of those.
Also, did I mention it's slow? It's slow. Don't try to simulate meshes with more than 5k faces or so unless you have a lot of patience.

Somebody should start a Cloth sim community of some sort because I think there should be a place where to share demos and advance this necessary technology.

So, the elements are there even in Blender, but the problem is that the simulation code is going to need extensive bug fixing.

You need to touch many breasts to achieve realistic jiggle physics. Many breasts. At least 150+, of all size, B to DD+. It's a difficult and time-consuming process that only the greatest 3d artists ever complete.

You need to palm them, and then slowly stir them, to get the right amount of force. Then you need to pinch them, but not too hard, and then try to slap them. Watch how they jiggle. If you can, buy 6/7 cameras to watch slowly and with numerous angles how they responds to action.

Then you need to milk them, slowly. Don't put too much strength when you milk them, women tend to not like being rough-handled here, and milking shouldn't be like putting breasts between two rolling pins, you won't extract milk like that.

Then you need to do the same with fake breasts, to understand the intricacies of fakeness in breasts.

If you do all of that, you can master jiggle physics.

How? Lidar don't magically negate the need for multiple cameras, they can't "see" behind objects because the laser pulse has to bounce back directly to the sensor

>>955418
I don't know much about the specs of the iphone's lidar (especially the scanning rate) but it looks it still takes some time to fully scan a scene. Recording a 3D "video", as in gathering a full cloud point at a rate comparable to a typical video frame rate would require tremendous computing power and storage.

How did you setup the icospheres/breasts so that they correctly "overlap"? I followed the tutorial but the breasts seem to deform notably before the cube reaches them. I even went into the .blend file he provides on smutbase and added a cube with a collision physics property with the same values as the cubes he's keyframed, but the deformation still happens before the cube reaches the boob. How come his cubes, and your icospheres, deform the breasts at the correct difference?
