we have a legacy `stadium` scene from turbosquid with animated vrayproxy multiscatter crowd:https://www.turbosquid.com/FullPreview/ ... /ID/669113
The crowd/seats etc. are Multiscatter distributed along splines.
In the past the viewport updated almost real time, now it freezes/updates for over a minute every time you move the timeline which is tedious and makes it impossible to do anything in the scene. It`s also slow just selecting a multiscatter object although not as bad as moving the timeline(which i presume is having to update all multiscatters)
Hiding the stadium often speeds the scene back up, although not always (until you unhide it again). All assets are on a network but as I said it used to run fine. I don`t know if this is something in Multiscatter, VrayProxy or maybe 3dsmax 2016.
I *think* i`ve noticed multiscatter slowing down while using splines as distributors/borders etc. rather than surfaces in more recent versions although I couldn`t say when the change happened (or if I might just be imagining it).
I do know that upgrading to 3dsmax 2016 has reduced viewport speed when using multiscatter but i put that down to 3dsmax 2016 viewport being slower in general, at least for my pc.
any ideas ?
