What's the relationship between the collision capsule width, the density, and the mass of a puppet?
For sculpts, with the exception of an edge case at density 0 making the sculpt near massless, the relationship between the value of the density tweak and the mass is exponential:
mass = 1000kg * volume in m³ * e ^ (6 * density + 2.96867907)
But for puppets, it's different. After overcoming the initial confusion of the puppet losing a small amount of mass while it's being held with R2, I worked out that the relationship between the puppet's scale and its mass was cubic as expected. But I haven't yet been able to work out the relationship between its collision capsule width, its density, and its mass. As with the sculpt, the density appears to have an edge case at 0 - but nowhere near as extreme as the one for the sculpt. Also, the density-mass curve is neither linear nor exponential - perhaps a polynomial?
As for why I'm interested in this. I have a puppet in a group, and its transform relative to the group is keyframe animated. But that makes it contribute zero mass to the group, so I'm experimenting with adding a puppet equivalent mass proxy sculpt to the group, and I'm trying to set up a network of calculators between the puppet and the sculpt to give the sculpt the correct mass.

Hrm... it should still be mass within the group. How are you measuring the mass of the group?
Perhaps the reason the minimum mass of a puppet seems higher is because it contains like 13 sculpts or whatever, each with their own mass?
As far as I know the collision has no effect on mass. It's just collision.

Yes, since I posted this I discovered that the puppet mass includes the mass of all of the sculpts in the puppet group. However, the puppet mass also varies when you vary the collision capsule width (not the collision capsule height for some reason) or the puppet density. It may be the case that the puppet density has no effect on the total sculpt mass component of the puppet mass, and only affects the collision capsule mass component. The relationship between the puppet density and the collision capsule component of the mass could still be an exponential similar to the relationship for sculpts - I'll need to investigate this further.

Interesting... I guess you can just delete all the sculpts and see what you're left with.
