- [Narrarator] When animating with objects that have been created in a virtual 3D space, one of the problems that we oftentimes run into, is the lack of constraints and limits that exist in the physical world. For instance, in our style scene, here, we have a simple door handle and latch set up, that if I just select the door handle, and with the rotate tool enabled and the reference coordinates system set to gimbal, rotate around the Y axis, causes the latch to retract and so behave in a manner that is physically plausible. The problem, though, is that currently I can just keep on rotating, and so have the latch travel an unlimited distance in any direction that I want. Which, of course, isn't physically plausible for the object that we are animating. To fix this, and so ultimately make the job of animtaing the set up much easier, what we can go ahead and do is make use of a limit controller. To accomplish that, with the handle selected, all we need do is jump into the motion tab on…
