Update
Added Anti-roll bar support for Suspension Stack component.
Anti-roll force is not calculated inside of the component but in BP that communicates between suspension stacks on the same axis:
AntiRollRatio is clamped to 0…1 range, where at 0 no Anti-Roll force will be applied and at 1 there will be virtually no body rocking as full anti-roll force will be applied. Keep it lower than 1 if you want a bit more dynamic driving experience (vehicle tilting in turns) or set it to 1 if you need a perfectly balanced suspension.
The function itself uses suspension forces of each individual stack and Anti-Roll ratio to calculate appropriate anti-roll force:
Anti-roll force is applied separately from suspension force. For this to work, new function in suspension component had to be made - ApplyAntiRollForce() , so you have to use latest version of the Plugin or Content to be able to call this new function.
