2012 Service Pack 2 is out


From what I have read, it’s an issue of how long it takes to open a file that uses a huge MSO material. Also the time it takes to start a render. But I haven’t experienced it firsthand (not using 2012 unless I have to), so maybe I’m wrong about that.


Not opening the file, but the “translation/scene prep” for rendering.



Not sure about that, but is the problem only happening when rendering with Mental Ray ?


As said above, the translation/scene prep" time before mentalray start to render is the problem.
The translation time escalates with big scenes.

The problem at work: We have a Multisub material with 100’IDs at work and we also have large scenes with alot of mesh in it. The problem happens with SP2 or Subscription Advantage Pack installed and not with SP1. (At the moment we are on SP1 and waiting for a hotfix :slight_smile:


I’d also like to know if it applies to all renderers or mray only…


Thanks for the responses everyone!

That is definitely what my problem was the other day - long translation time - so now at least I know it wasn’t something I did wrong. :hmm:


Yep thats what it was. I just confirmed it through my reseller


No update on this, after a half year?


It seems to be fixed in max 2013 but afaik there was/is no info available on a fix for max 2012.


Money, money, money - OUR money…

Why fix something for free, when you can sell it as Max 2013?


Ken stated somewhere (i think in the 2013 announcement thread), that there is an update in the works for 2012. No release date or so given, nor if this specific bug will be fixed or not …

can’t find the info right now, so maybe i was just dreaming and my memory is playing tricks on me


You mean #136: http://forums.cgsociety.org/showpost.php?p=7219503&postcount=136 ?

I am wondering that AD need so many times to fix a problem that was introduced in a service pack… Does they have so little man power with the how-to to fix a bug?


The bug was in mental ray, not max. Therefore we had to have others fix it and then we had to integrate the new changes to the mr build. If you’d stop assuming that everything is trivial to do you’d probably have better expectations about how this stuff works.

I’m 90% sure it is scheduled for our 2012 SP. Yes, we fix “old” releases despite our money-grubbing ways.


Ahem…don’t you mean current releases…:wink:


This fix is indeed in the next 3ds Max 2012 Update. The defect is: MAXX-5824 - Major increase in translation times with multi-sub materials in mray

It was fixed in the 3ds Max 2013 code and was then cloned to the 3ds Max 2012 update code branch and is set as closed/fixed.


The issue causes a huge slow down when opening the material editor too.


So we have not installed anything other than the first hotfix, mainly because we keep hearing that this is slower or that doesn’t work now, or multi-sub materials are now slow…
Is there any kind of projected date for the latest SP for product update for 2012?
Will the latest HF/PU address the dreaded viewport lag?

We have been out of the loop a bit with crazy deadlines etc…



has anyone else noticed a longer start up time with Max 2012 after PU-6?
Not a big deal, just wondering if it is just me.


Yep, after loading of plugins is completed the splash screen sits there for much longer than previously.
