Parametric detach by Smoothing Group or Material ID

Submitted by harumscarum on Sat, 2016-02-06 04:09

Hello
I'm very into parametric modeling in 3dsmax and use Smoothing Groups or material IDs to create set of reference object which easy to modify through the source object.
Need to automate this routine.

For example we have object with several different Smothing Groups assigned:

- run script
- number of Reference Clones are created with Volume Select + Delete Mesh + PolySelect modifiers
- number of Clones is equal to number of SG (or MatID).
- Volume Select with Face / Invert / by Sm Group (or MaterialID) paremeters
- keep source object with Display as Box parameter

hope it will be useful not only for me
Viktor

Hello, Something like this?
