[3dsMax] Smoothing Groups to IDs

GhosTDoG

Hi,

I'm looking for a way or a script, that "converts" Smoothing Groups to (Material) IDs.

Thx

A script would be handy and easy to develop -- but if there isn't one you can grab, a manual way would to be just to select by SG number and assign an ID to it, those two windows are right next to each other too, shouldn't be too cumbersome or time consuming to manually do.

Thx. However, in my case I need a batch process, but I didn't find any scripts so far.

It's easy enough to write a script that converts a smoothing group to the same number material, but how do you want to deal with faces that have multiple smoothing groups (since a face can only have one material ID)? I ask because I already wrote a script for this but it just takes the first smoothing group (in numerical order) applied to a face and uses that as the number for the material ID.

I don't need to have the same number, like "SG 1 = ID1".  "SG X = random ID" would be enough.

Or maybe an angle based poly selection to IDs?

Since no one else has responded with something better, I'll just post this here: https://www.dropbox.com/s/2h0bykcupaj407f/sgToMatID.ms

Notes:

1. Script does a direct ID conversion from SG to MatID (so SG 5 becomes MatID 5)

2. If a face has more then one SG only the first in numerical order is used.

3. Only works on Editable Poly objects.
