Here the model OBJ was Decimated by 90% but always some heavy! :)

Hi Pilou, it looks like that is a triangle mesh object, not one that is structured as a sub-d object. So it won't really convert very well with the sub-d converter which expects to process a sub-d control cage.

Could be a good candidate for one this new quad remesher posted in the other thread.
I would be curious how the poly flow will look like.

<< triangle mesh object

I have totally forgotten this apect of the problem! :)

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

PS when i said 90% it's a big Decimation! (10% will be quasi no decimation)

Here the model OBJ

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! ;)
http://moiscript.weebly.com/uploads/3/9/3/8/3938813/insectok.zip (3DM 88 meg)
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 ;)
