I have been struggling getting physics constraints to be truly locked in their locked axis, I am using a few different constraint types but even a fully locked constraint is springy/wobbly. Is there a special set of options that need to be set to make this work? Is there some other method that can lock two (or more) meshes together that behaves like this (but not parenting)?
Edit: For more context, I am building a modular vehicle building game where the components are all attached to each other via locked constraints. I originally tried parenting instead but ran into issues when it came to the more advanced interactions that I am trying to allow. Everything works great but the rigid constraints are just a little too springy.
