"Did you uncheck the "Keep in memory" box in proxy settings? I think that should do the trick." .....
what do you mean by keep in memory because i haven't seen that option in the proxy converter script. or did you mean "cache in Ram" under the proxy property settings? either ways its always unchecked by default so i am not quite sure i understand how you saved ram.
I also have this issue where size of my scene is like 50mb but the size of proxies used are like 500mb( if they were actual meshes)yet when i hit the save button it takes like 5 seconds to save the scene but when the autosave comes up in every 5mins(as ive set) it takes like 60 seconds or more to save the scene as if it takes the proxies into full consideration as actual meshes... i dont know if anyone gets it? is this just normal cos im pretty damn sure it dint happen in my mental ray days and with corona while i was still on 3dsmax 2014 and it dint happen with corona 1.3 on my current max 2016. both ctrl save and max autosaves had similar save times i believe or are supposed to ,right??? so now i am forced to go with autosaves every 15mins instead when working on huge scenes cos the time it takes to autosave such huge scenes can be annoyingly long it eats into production time of the entire project on the long run. just thought i should put it out here maybe im not the only one getting this and there is an actual solution to my problem cos i really dont know much about these things , im just observant .thanks
