Title: corona and multi instance of 3dsmax.. help!
Post by: orenvfx on 2016-11-17, 21:25:58

3dsmax 2016 and corona... simple scene.. when i lunch 1 more copy of 3dsmax 2016 its like all the selection (faces... objects.. verices...) start to be laggy and slow...
its not the memory. i got 32 gb

 i mean even with 2 cubes... when i shut down the extra copy of 3dsmax 2016 its back to be fast again... any idea??

i really want to check the option to move from vray to corona...

Are you rendering with both instances open?
I found max 2016 to be unstable and often unuseable at the best of times too. Have you tried 15 or 17?
The viewport speed is often down to your GPU. What GPU do you have?

As for the move from Vray to corona...DO IT
I promise you wont regret it.

thanks for reply

im not talking here even on rendering processes... in even with 2 cube on the scene and in the other copy is empty scene

i try it on max 2017 and its the same... only on max 2014 its work with 2 or 10 copy smooth... :(

i wonder if its autodesk or even windows 7 issue...
btw i got gtx 750 ti and i try with gtx 1080 and its the same.. so its not the gpu

please if you guys got more ideas it will be great!

thanks

This one is sounding purely like a 3ds Max issue (or indeed a Windows issue etc), since no rendering is involved; have you followed up with Autodesk and on Max forums too? Or is there a reason you think Corona is involved? One way to test would be to uninstall Corona and see if this still happens.

This sounds to me like an issue specific to you to be honest. Ive worked daily for the last 2 years with mutliple instances of max 2014, 15 and 17 open. Quite often at the same time and ive never had a problem especially with corona.

They've been in touch with Autodesk, definitely a Max issue of some sort.

Must be with 2016 only. I think i used it for 2 weeks before downgrading back to 15. Just saw the guys post in 10k hrs.
Definitely dont have this problem with 2017. Probably have 3-4 copies open at once daily.

step to check if you have the problem
1 - open max 2016
2 - create some boxes.. convert them to poly
3 - open 1 more copy of max 2016 (empty one in background)
4 - grab 1 box and press 4 to enter to poly mode... keep press off and on ... of and on.. its should be fast with no lag...
5 - try to select randomly boxes on the scene... its should select them fast
6 - try to open the customize dialog box.. its should open fast
this is the correct situation

in the unwanted situation all the steps happen slow and lugy... once you shut down the extra copy of max is return to be fast

I have max2016 SP3 and has no issues with multiple instances whatsoever. Did you try to check it with other renderers active, to completely rule out Corona's influence?
