Autodesk 3ds Max Design 2010
Tip
Speed up
Revit FBX Renderings in Max Design
I would like to share a tip I got from a great colleague,
Jennifer O'Connor. Some of you may know Jennifer as
president of the
Northern Illinois Autodesk Animation Users Group in
Chicago. Jennifer, an Adjunct Professor of 3D
Technology at College of Lake County and president of
4D Artists Inc., is
about to publish her first book - Mastering mental ray
for Design Visualization using 3ds Max Design.
Look for it early next year.
She shared this tip on how to speed up Revit FBX Renderings
in Max Design 2010. I have found it works very well in
both 3ds Max Design 2009 and 2010, and can be a tremendous
timesaver. The issue appears to be related to
the pre-processing of Multi/Sub-Object materials.
If when rendering, your scene takes a long time to
pre-process or it appears to hang during the pre-processing
stage, this tip is for you.

Speed up Revit FBX
Renderings in Max Design
A simple change in the
DesignVIZ options can vastly improve mental ray
Pre-Processing when rendering scenes imported
from Revit FBX files.
In Notepad, open the file "CurrentDefaults.ini
in your local User's files (typically at
C:\Users\YourUserName\AppData\Local\Autodesk\3dsMaxDesign\2010
- 32bit\enu\defaults\DesignVIZ.mentalray\CurrentDefaults.ini").
Search for the parameter 'DontRepeatRefMsg' and
change it's value from 0 to 1.
Four lines down is the parameter 'InvalidateTMOptimization'
and change it's parameter from 0 to 1. You
should now have:
DontRepeatRefMsg=1
; comment comment comment...
; comment comment comment...
; comment comment comment...
InvalidateTMOptimization=1
Pre-Processing at the start of mental ray
rendering should now happen in a few seconds
instead of minutes.
You have to restart Max to accept the change.
You should also edit the DesignVIZ.mentalray
preset at your program installation folder,
usually "C:\Program Files\Autodesk\3ds Max
Design 2010\Defaults\DesignVIZ.mentalray\FactoryDefaults\CurrentDefaults.ini"
Be sure to do the editing for both x32 and x64
if you have both installed. Editing the INI file
in the Max installation folder prevents a change
if you choose an option from the
"Customize>Custom UI and Defaults Switcher".

As a quick reminder, you should
always check to make sure you have the latest FBX plug-in
installed. You can easily determine if you are running
the latest version by clicking on the "web updates" button
at the bottom left-hand side of the import dialog box.
If you are not on the most up-to-date version, you will be
prompted to click on a link where you will be able to
download and install the latest version. This plug-in
is updated quite frequently, so check this often.
