I guess it depends on how you're looking at it. There's no point in a semantic melt down ;) I mean that for all cases, there can always be a single frame where Result Value equals end value, but only two cases where values reverse sequence and those are mirrored loop and mirrored loop once. That kind of makes the backwards premise odd to me. It is equally constructive to simply see if something is increasing or decreasing, which isn't synonymous with the interpolate being on the front side or back side of the loop either, since start value can be greater than end value. The requested functionality of "backwards" strikes me as odd, off the top. -GT > > > On 2 November 2010 13:33, George Toledo <[email protected]> wrote: > >> Something can only "go backwards" in mirror loop, so in that way, the >> requested function of being able to tell "backwards" was kind of a quirky >> premise in and of itself. >> >> -GT >> >> >> On Tue, Nov 2, 2010 at 9:30 AM, Chris Wood <[email protected]> wrote: >> >>> Yep, if the point at which it hits 1.0 isn't the exact time it gets >>> rendered, you don't get 1.0 and have to use tolerance.
