Get Used Material ID List from EditablePoly without face check

Submitted by Matyrix on Thu, 2018-08-30 04:08

Hello,

Everybody on other forums use the check every face to read the Used Material IDs from an object, but there is a basic ID list in Editable Poly. I attached an image about it.

The only problem is that there is no chance to read this list from the Editable Poly.

Do somebody knows how can i read this list by script?

Thanks a million Vojtěch.
I couldn't run it in 2014 (Global.IGameMesh is absent), but in 2016 works just fine. But it is surprisingly slow compared to what I've posted above. 4kk mesh processed in about 9-10sec

Yeah, IGameMesh is more about convenience than speed, though I wouldn't have expected it to be that slow either. That sounds like even snapshotAsMesh+getFaceMatID in maxscript would be faster.

Some of my scripts and MCGs :: 3ds Max SDK Intro for Scripters
