BootyMagic alpha 1 release

Arr! Booty! 🏴‍☠️

Features in the first alpha:

Default physics settings

The default physics are intended for an average sized butt that isn't particularly muscular or toned or firm, but isn't particularly high in fat either. It should be a good starting point for adjustments made by changing the softness and quickness values later on, as well as for dynamic adjustments due to gravity / pose.

The main differences compared to VaM's default physics settings:

• Spring is increased a lot from just 7.00 to 65.00. The low VaM default value makes the glutes move a lot more easily but at the cost of being very slow and "floaty". In BootyMagic spring will be high to keep the glute joints more firmly in place, and additional movement and change in shape will then be applied with morphs.
• Up/Down Angle Target is at 0 instead of -10. This slightly compensates for the fact that the increased spring pulls the glutes up, and 0 is a better starting point for gravity (hip angle) based adjustments.
• Fat Back Force is much higher. It seems to be beneficial when used with high fat spring.
• Both Fat Spring and Fat Mass are increased. Increasing fat spring was important  to prevent the glutes from stretching and compressing weirdly, especially with forward-back hip motion. It does make glutes look more static, but I'm hoping that morphs will improve upon that.

Physics params window

View current value, offset the parameter value, apply offset only to left glute.

The twist angle target parameter is removed, for some reason it just doesn't have any effect on the glute joint.

The max value for Fat Spring is 2000 instead of the usual 500, this is just to accommodate possible very low softness values. (In TittyMagic the main/outer/areola/nipple group based multipliers took care of that.)

Hard collider configuration

It works just like in TittyMagic, but there's just the one hard collider per glute for now. The plugin doesn't apply any automatic changes to the collider's size, position or collision force (which is actually the collider's mass).

Friction implementation

Implementation copied from TittyMagic.

Both hard collider and soft collider friction can be adjusted and used with Adaptive collider friction to auto-adjust based on skin gloss and specular bumpiness.

In addition, hard collider friction falls off with distance from the collider's original position. This prevents it from sticking to colliding objects and causing the glute to move when there's no contact on the skin. It's not a very noticeable improvement just with the single hard collider, but it will be more important later if I manage to get the extra hard colliders enabled when soft physics is on (as mentioned in the development status post). You can easily tell that the colliders are much more sticky when there's many of them by touching the glutes with soft physics disabled.

Compatibility with TittyMagic v5.2.2

Out of the features listed for the first alpha in the development status post, these are not yet included:

• automatic calculation of glute mass - the calculation works but is not used yet, instead mass defaults to 1.000 regardless of butt size, you can offset it from that if you want to
• automatic physics settings based on mass, softness and quickness - the physics settings don't yet adapt to these

The Morph Multipliers and Gravity Multipliers tabs are intentionally empty at this point, and most features in the main Control tab are disabled. 

Regarding feedback I'm mostly looking for:

(1) Reports if the plugin crashes or stops working, or if some slider or button that should work doesn't do anything. It's alpha only in terms of features being incomplete though.
(2) What you think about the the default physics settings, anything that stands out let me know!

I'll probably do a small development status post in a few days, have to do some research, planning and testing first.
