The implementation of the "Minimum Neighbor Distance" rule is crap.
It does not aggregate the results from the particle-particle checks. Instead, it only keeps the result from the last check.
the plugin is totally awesome, it really useful and easy to use, however, i wonder if orientation or up vector kinda feature is reasonable to add-on?
as you can see the image i attached, some fishes are off their orientation after few turns, this is obvious when come to certain amount of closeup, thank you for looking into it.
With the R20 API compatibility changes, a bug crept in. Boids that try to avoid static geometry will now seemingly disappear, and possibly briefly re-appear somewhere else. It's probably just an ill-considered change in the Matrix transformation code (that threw quite some errors in R20 before the API adjustments).
