VaM 1.x How to make someone lie naturally relaxed on a bed or the floor?

[Jocks3D]

This is another one of those simple basic questions I'm kind of embarrassed to ask. How do you make a model lie on a bed or floor so their body is relaxed, like it would be in real life? Right now when I place a model horizontal on a bed they're stiff like a mannequin, when their body should naturally sink into the bed, letting gravity do it's work. I seem to recall there was a setting that could quickly do this but I can't remember what it was.

You could try decreasing the overall spring strength in the Control & Physics Tab. What you can also do is place the Person Atom over the bed, then disable some controls (such that it falls naturally on the bed) and then re-enable them.

Setting major control nodes to Off will do that, but there has to be something underneath them to collide with. If you position the model just above where you want it, and in the right position, then you load a non-root pose preset that sets those nodes to Off. The model should settle onto the floor and be very loose.

Most beds do not have real soft body physics, but there is one here:

Soft Body Physics Bed - Assets + Accessories -

-- Note: - Contains a .dll file to disable inter-collision within the bed's physics rig + force rigidbody physics sleep threshold to 0. -- Contents: - CUA Bed asset with mattress soft body physics, contains both wood & modern style variants. --...

Soft body bed is the only bed I use.

Thanks guys for the tips but I could use a little more details:

@Geraldo "What you can also do is place the Person Atom over the bed, then disable some controls (such that it falls naturally on the bed) and then re-enable them."
Which "some controls" are you referring to?

@SlimerJSpud "Setting major control nodes to Off will do that," and "load a non-root pose preset"
What do you mean by "major control nodes"? And where do I find non-root pose presets?

Also, can I assume that placing a person on a floor or table will be enough for them to collide with it?

What we are all referring to as "controls" or "nodes" are the green squares that show up in your screen when you press T on your keyboard. These are in fact what control your character's poses, and the body parts will try to follow that position based on the spring and damper settings. For example, if you click the green square near the right hand, you'll see that a pop-up menu will appear with the "rHandcontrol" name. Moving it will move the character's right hand around. What I meant by decreasing the "spring" settings is that the character's hand will try to follow the node position according to the spring strength. Higher spring = more closely following the position you're setting it around space = more rigid behavior.

Then there's also the On and Off setting for each individual control of your character. By default, only major control nodes are active: head, chest, hip, hands and feet. There are several other controls that you can enable/disable, and most of them are usually set to Off. What we're saying is that you can also turn some of these major controls to Off, or even all of them, as long as your character is placed above an object that has collision. What will happen is that the body will ragdoll and fall over the object (bed, table, floor).

Most poses and animations have the head, chest, hands, hip, and feet on, with all other nodes off. Overconstraining the other nodes results in stiff people, IMO. Take a pose preset, or make one you like, and save that with the root node saved, and with the above control nodes on. Once the figure is in that position, you can either set those nodes to off, or save another pose preset that does not have the root node saved, which sets all the on nodes to off.

Assuming there is a surface with collision below them, setting all nodes to off will make the model collapse onto that surface.

By on and off, I'm referring to the position and rotation settings on the control nodes. You have on, comply, off, and others. The wiki explains these.

You could also try doing this in one shot, where you have a pose preset with the root node saved, but all the control nodes off, and see if that results in a naturally limp model. I did that in one scene, but the pose needed to be reset periodically, because the model would drift out of position with everything off.

Thanks guys! I also like the suggestion of finding an existing pose of someone laying down and playing around with that. I totally forgot about this option.
