configured ghostsheet with default length constraints
added default length constraint to be used by all bones without their own (before this allowed for full compression, which almost always gives bad results)

resetting bone transforms on cloth when it's re-enabled to avoid spike in velocity with LODing
pickaxe chain controller LODing
min/max length constraints respected properly and slightly reduced precision in collision detection
corrected LODing on cloth controllers for ghostsheet
Re-mapped weight curves to relaxation values
- also reorganised cloth material SO to make it a bit more readable
some chain material setups
fixed wrong rotation constraint axis being used for one of the limits
basic gizmos on constraints
fixed length modifier and gravity on capes
ghostsheet setup, split bone controllers for better collision control
improved edit-time gizmos so you can see colliders and constraint setups
split gizmos between configuration and playmode
cloth changes
- filtering raymarched collisions with a large distance from bones to improve stability with extreme rotations and the cost of some clipping in these cases
- made sibling constarints a bit stricter
constraint tuning
- sibling linear constraints are directonal, taking the average of the orientation between them
- parent receives half the constraint easing as well
- tuned some cloth materials for these changes
converting rotation constraints to radians when processed
drop tickrate on some cloth assets
contacts are found once at the beginning of the tick and solved alongside distance constraints
Separated rotation constraint data from bone data
improved collision responses to be resolved positionally without adding velocity into the system
fixed summing of position adjustments with sibling constraints and removed their rotation contribution
reduced max tick rate on cloth
simplifying burst cloth in prep for separation as jiggle-only solution
- position based dynamics, with hard rotation constraints
- configurable relaxation factors to allow for artist control over bounciness of constraints
additional profiling, a few quick wins on performance
initial skinned oni cloth setup for ghostsheet
small perf modifications to oni cloth and initial setup for global solver updater
adding obi cloth - still need to clean out samples and other fluff
switch to velocity verlet integration
hitbox gizmos match their actual size
more burst cloth
- changed integration method
- reduced position and orientation to a single spring value each, collision still managed with separate spring
- cleaned up unused cloth material properties
further burstcloth modifications
- collisions resolved with spring forces
- added dirty broadphase to collision resolving
- capsules colliders reinterpreted as sets of spheres, cheaper testing outweighs increased collider count
- added collections packaged for better native containers
some initial balanced values for some cloth assets
improved burstcloth
- replaced hard positional constraints for length and shape to force based spring system approach, aiming to give artists more control over the bounciness of joints but also allows motion to propegate better
- sibling constraints are also treated as length forces
- removed now-unused fields from material
- other small improvements to reduce overhead
burstcloth improvements
- rotational constraints respected
- constraint normals are correct now, significant improvement to length constraints
- some jobsystem/burst optimizations
watersystem handles casts made from underwater properly
- no false positives when slightly underwater
- able to get a positive result when looking at the surface from underwater
added simple pid implementation for controlling orientation when steering - needs more tuning
