    Hi,

    Currently, HingeJoint in Unity allows a maximum limit from -PI to +PI.

    PhysX, however, doubles this limit from a total of PI*2 to a total of PI*4 since version 4.0 with the use of the eENABLE_EXTENDED_LIMITS flag.

    Would that be possible to include in Unity anytime soon? Even as optional setting. This would be incredibly helpful for our project.

    Everything is documented here and here for anyone interested.

    I believe this is mostly a question for @yant ?

    Regards,
    Stepan

    I believe that should be possible (unless some massive internal stuff depends on it). I'll add this to our tracking sheet, but won't be directly able to say when (if) it becomes available. Thanks!

    Getting this in Unity 2021 would be lovely, but still, great news! Thanks :)

    Yeah, I understand. Just wanted to say that 2021 is a complete thing now. No new features are making it there...

    Oh, I wasn't aware of that. Thought that 2021.2 can still add features before LTS comes out. No worries then, I will try to skip 2021 and only update to 2022 later :)

    Nope. Features have to land before an internal cut-off and that's during alpha. During beta, only bug fixes are allowed. This has been like this for years and is part of the stability rules. LTS takes it a step further and only allows selective bug fixes to land based upon bug "user-pain" which is an internal metric taking in certain criteria.

    Makes sense. I guess I just hoped for this to land in 2021 for example in the somewhat recurring "Features" or "Improvements" minor version changelog sections. These contain only little things, I know, but I believe/hope this to be a small thing as well.
    Not trying to argue, just explaining my POV from previous comments.

    Not a problem, just wanted to explain how it works. Yes, the minor version does include features, improvements and bug fixes but not if it's already out. 2021.1.x or 2021.2.x won't get anything but bug fixes.

    There are two releases a year so 2021.1 and 2021.2 are out so only bug fixes for those an all previous releases. New features go into 2022.1 onwards.

    Hey @Gooren,

    Thanks for bringing this up to us. We have exposed eENABLE_EXTENDED_LIMITS flag. In the Hinge Joint component you will find a checkbox that enables extended limits for a hinge joint. This will be available in Unity 2022.2.0a8 and up.

    Extended thanks to @yant for actually putting this into the internal tracking sheet.
    I appreciate this attention to detail!
