animBoost is a set of maxscript that boost viewport performance for animated mesh.

Recently I found out that 3ds max still evaluates an object's modifier stack even though the object is hidden. I always assume that's not the case. For a non-animated object, this is not a problem, since 3ds max internally caches the final result of modifiers stack. But, if a hidden object is deforming over time, 3ds max wastes a lot of resources for this invisible object. For example, a typical character rig would have a low res proxy for faster playback. But, it becomes useless, since skinned hi-res mesh will be calculated anyway.

animBoost is an workaround for this problem. animBoost keeps monitoring scene and selectively turns on/off modifier when object is unhidden/hidden.

v0.8 Update
bugfix - If you turn on/off with Layer, eveything is OK. But, when you hide/unhide each nodes, animBoost forgot to turn on Mesher/SuperMesher/XMesh. This has been fixed.

v0.7 Update
Support SuperMesher
Support Frost
Support Mesher

Additional Info: 

How to install

Download zip file. You will see two folders(Scripts/UI) after unzip the file. You need to copy those two folders into your 3ds max's Scripts/UI folder.

How to use

Launch 3ds max. "Go to Customize User Interface". Select "animBoost" category. You wil have 3 new actions. Make buttons or assign shourcut.

"turn on animBoost" will show up as "animBoost_On" button. "turn off animBoost" will show up as "animBoost_Off" button. "animBoost manual mode" will show up as "animBoost_Manual" button.

Now all you need to do is click "animBoost_On" button. Now animBoost is monitoring your scene and invisibly turns on/off modifiers when you hide/unhide objects.


If you have a lot of modifier heavy objects, THERE WILL BE DELAY when you hide/unhide objects.

If you have any problems with this script, you can always click "animBoost_Off". Then animBoost will be removed from memory.

animBoost also support a "manual mode". Instead of using "animBoost_On", if you use "animBoost_Manual" button. You can run animBoost routine manually. If your system is really slow or you dont like the delay, you may use this.

Max 2013 up6 all work fine

I am using it right nopw with max 2013 and it works fantastic. I use CAt and I hide my mesh by unticking the Geometry category and it plays in real time 24 fps. It was playing at 3fps before animboost. I wonder why max always want to calculate what's hidden...

A few thing..

Since all animBoost does is turn off modifier, it only works well when you have very heavy deforming modifier such as Skin or MeshSmooth.

If your rig is slow, animBoost does not do anything for that.

If you have any problems, I need more detailed description. If you send a sample file, that's better.
