surface not perfect

[kwaikeong1402]

After rendering, i found that the surface not enough smooth. Is it the modeling problem? Anybody can assist me to solve this problem? Thank you very very much......

What software did you model it in and what did you export as. It looks like a poly mesh OBJ perhaps. If thats the case then you need to adjust the mesh density before export

This model done at solidedge,can adjust at rendering toolbar?

Ok i checked with SolidEdge and there are no advanced import settings as such, so it should be a setting in SolidEdge for adjusting density or tessellation

i am not a solidedge user...but usually for obj import and export this problem usually is related to normals and not edge tessellation.
Check that your exporter has an option to export normals a well (its just extra information stored in the file nothing more than that)
