FAQ (Frequently Asked Questions)

When updating the asset I see a warning saying that the spring size is not valid

During the first asset verison the rotation spring changed quite a lot. The rotation spring is mostly used in the TransformSpringComponent. So those objects using this component can trigger this warning. To fix it you can either create a new instance of TransformSpringComponent and copy the values over. Or you can try using the method explained over at Fix Spring Size Warning.

In some cases my spring will oscillate out of control

This is a rare occurrence typically associated with springs using very high force values (much higher than any of the values used in the Demos which are super stable at any framerate). The default integration method prioritizes performance, but in extreme cases, numerical instability can cause oscillation. To resolve this, simply lower the Force Threshold value in the Asset Window settings. This will make more of your springs use the analytical (physical-based) integration method, which offers superior stability at a slight performance cost. For maximum stability, you can set the Force Threshold to -1, which forces all springs to use the analytical solution.
