3ds Max Design 2012 Renders Slower

[Peterhus]

I've upgraded to 3ds Max Design 2012 from 2011 and it's rendering twice as slow.

 

I'm using Mental Ray for my animation and when using 2011 I get all 16 Buckets (Guessing it's 8 core and 8 HT, I have 2 quad core E5620) but when using 2012 I only get 8 buckets and not 16. Why this? this doesn't make scene, I still have multi-threading ticked.

 

Also in between "Computing Final Gather Point" it's "Translating Scene..." for about 10 to 20 seconds long where as in 2011 it's more or less instant.

 

I have updated to the latest Sp1 from Autodesk website.

 

Any ides?

20 second is not that long for animation, are you using the same setting from your previous max? as your scene gets bigger then max takes longer and longer to render max has to calculate everything in your scene from the objects, models light keys special effect etc.

 

If you have a small scene then max will take less time to render

The file is the same for both 2011 and 2012, I have made no change to the settings.

 

10 to 20 seconds to "Translating Scene..." in 3ds max 2012 is a long time compare to 3ds max 2011. Still doesn't explain where I have 8 bucket instead of 16 and that why it take twice as long to render.

 

Any ideas?

Something I've noticed too.....and in a big way!!!!. I've spoken to my Support and subscription company who have told me that they have been inundated with calls with the same problem this year but no one can pinpoint a problem.

 

The first time I realised was when I had rendered 2x high-res images overnight using 2011. Months later when the project was re-visited with basic changes the same images took an extra 9 hours to complete. I've also never had as many render errors than I've had while using 2012. In the begining 2012 was working perfectly, but progressively went downhill over a few months.

 

I've searched endlessly through the net and found quite a few threads about the same problem, however everyone seems to have a slightly different issue with it, which is what Support had told me as well (reason they can't pinpoint the actual problem).

 

All I have done is test after test to find what settings seem to trigger extra render times and avoid them. An interesting one I found was, I can not use the 'Map Manager' while DBR - my renders freeze endlessly at 100% complete, and they are not recoverable. When this happens I have to force Max to shutdown via the task manager.
