Physics in Unity

AssafHayut

Hey guys,
We started using physics pretty heavily in our company.. we only recently realized flipping through screens of the game also has an effect on physics and sometimes it behaves unpredictably or simply flat out bad: for example we've added very sensitive physics on water lilies that when the user flip to another screen the they go berserk.
What can I do to avoid it? Can i simply turn off the effect unity (or anything outside the actual animation) has on the physics? Should (and can) I bake the physics? (not idle since we have loops and/or tracks following that are interchangable). Are there any other properties I should know in regards to Unity's effect on physics?
Thanks a lot

To address the issue of physics behaving unpredictably when flipping through screens in Unity, you can adjust the Physics Inheritance setting in the Advanced section of the SkeletonAnimation component. This setting allows you to control how the physics constraints of the skeleton are affected by the GameObject's transform movement, effectively isolating the physics from external transformations. Additionally, while baking physics is an option, it may not be ideal for dynamic animations with loops or interchangeable tracks. Instead, focus on configuring the physics settings to ensure stability and consistency across different game states. For more detailed guidance, you can refer to the Spine-Unity documentation.

Spinebot Thats super intel. Thanks a lot.
Do you know if lowering inheritance will effects all physics globally or can I tweak specific bone's physics?
Thanks again

AssafHayut The Physics Inheritance setting of the SkeletonAnimation component affects the entire skeleton. If you only want to reset specific physics constraints, it's best to call the PhysicsConstraint reset().

Regarding baking, I believe Spinebot's response might give the impression that baking is possible, but in reality, what is generally referred to as "baking" cannot be done. While the 4.3-beta version did add a hotkey called “Key Constrained,” which allows you to save the current pose at a specific frame, this is merely a starting point for modification when you absolutely must convert an animation to one that doesn't use physics constraints. It cannot reproduce the movement achieved by physics constraints throughout the entire animation, and it is not intended for use as part of your regular workflow before exporting animations every time.
