Hi,

I downloaded this mesh from the internet. I am trying to smooth is as usual with SubDivide. But it’s not working. All the seperate mesh faces subdivided, but there is no smoothing.

What other options do I have to smooth this ?

recommended:
clean up the mesh - especially the triangular faces. then…

you have to convert to SubD first
_toSubD
now
_subDivide
works as you expected
