    Setting limits with Position params

    I'm trying to set positional limits for some bones used on wt. mapped geometry. They're simply sliding some shutters & doors on single axis. The sliding part all works fine but I'd like to put some Stops in.

    Thinking back, I guess I've never had need to set a position limit before & I've never had issue setting rotational limits. But I'm not grasping something with setting of position limits for some reason. The -1 to 1 thing has me confused largely & how that correlates to X-pos for example. Wiki docs describe rotational aspects but are scant else wise, & haven't searched for vids yet.

    I'm sure there are a myriad of ways to accomplish this, but this is a pretty basic thing I'd like to understand & hopefully not have to do battle with it each time I have need of this function.

    The Min and Max are whatever you want to set. They are -1 to 1 by default to indicate a 2m limit. Make a room and ad a chair object. Now set the position limits for the chair to only be in inside the room. It's quite easy once you get going

    PS. You can set the limits on a null and set the bones to "same as item" to copy the null)

    Thanks BeeVee. I got it working just this morning.

    The UI could use a bit of TLC. It doesn't respect the units set in Preferences so only works with meters, nor let you do conversions in the requestor box as most of the other panels do.

    For setting Rotation limits, there are hotkeys {} for transferring the value set in the viewport so you've a visual guide to set the min & max in the panel. Those don't work for position apparently. Are there equivalents?

    Interesting! The interface hasn't been updated for a long time. Send a bug report for the things like conversion and math. Those should work, it wouldn't be a feature request.

    OK. Good to know. I'll check a few other things in the Motion Panel while I'm at it then.
