It is the successor of Subdivision Reversion maxscript.

• It is now 100 times faster, being a native 3ds Max plugin, not a maxscript anymore.
• It has the ability to reverse just parts of your models based on your selection.
• It can reverse multiple iterations at a time.

Here are some of the benefits you get:

• If a 3d model you buy online has it's modifier stack collapsed it is almost useless, you can't edit, unwrap, rig it, but with TurboReverse you can reconstruct the first subdivision level and then do all the above.
• If in your production pipeline you need at some point to collapse the model with TurboReverse you can get the subdivisions back later.
• When you apply a turbosmooth modifier to a reconstructed subdivision level you will get exactly the same mesh as the original.
