Hi Pilou,

> So what is best : quadrangulate then decimate or decimate then quadrangulate ?

It depends on the quadrangulation method. Some of them can incorporate polygon reduction built into them so in that case you would probably not do any separate decimation.

You probably would not want to do decimation afterwards though, if you were to use it probably use it before.

So with ZRemesher of ZBrush always the same Insect by Digital Archive of Natural History

27 000 polys to 13 800

Inside ZBrush





Very speed to reload inside Moi by SubDiv as they are quadrangulated!
Many more easy manipulable (even it's an 94 Megs 3DM file! ;)

The OBJ quadrangulated is 950 KB ;)

The Importation inside Moi with Import OBJ take a little more time (3-4 times the SubDiv) but works also!



Always with the Free SimLab Composer Lite ;)

Very very good result!!!
