Wasuuuuuuuup Spiral.
I won't get your hopes up, I have never fixed this problem before, but I am familuar with it (Asylum of Mortality also has this glitch). I'll just share what I know. Confirm some things, hopefully bring a couple of new facts out, and maybe lead to somebody solving this crap.
* This error is only visible to clients.
* Degree of rotation is too consistant to be random rounding error.
I haven't done enough testing to say for certian, but I am GUESSING that there has to be a large number of 3do's for this error to happen (somebody test this!).
I don't know WHY the error happens at all, but I have a gut feeling it has to do with the translation of PYR to LVecs.
Btw, setting the LVec of all the 3do's to straightin them SHOULD work fine, and if the only component of the PYR your models use is the YAW, you should be able to flatten their LVec very easily with no other reference object. If I can't figure out a better way to fix this with Zeq and them, I'll write up a quick cog that guy could add to his cog that would flatten out the pitch/roll of your 3do's on startup.
One day, after everybody else quits, I'll be the best.
