Maya normals on triangulated faces after boolean?
Hi all, I'm trying to model a car in Maya and use mental ray render.
let me explain a little about this issue that I would like to discuss.
With curvy surface like car exteriors, whenever I need to punch a hole, it becomes very hard to hold the curvature nice and smooth.
So instead of pushing vertices back and forth for ever(like I used to do), I tried to use boolean this time. Yes, the taboo.
so I divided the car door piece to a good density, placed a "handle" shape piece and did boolean. after that extruded the loop a couple time to get a good beveled edge.
Although the shape is good now, comes the n-gons.
I select them through "cleanup", and did a "triangulate".
that's where the normal issue kicks in! (thank you for the patience, phew)
the tris show the facets while the quads looks smooth.
I tried to select all of them and "soften edges", it only made it worse. "unlock normals" or "average normals", no improvement either. I tried all the tools under "Normal" tab in polygon mode, but could not get a smooth looking on the door piece.
so my question would be, is it possible to make a smooth piece out of this method? or I have to clean up the tris no matter what I do?
I saw this car model in Maya converted from CAD file and it has smooth surface even with the tris:
I know nothing about CAD, but from manually doing it, is it possible to do the same thing to get smooth looking model?
if you have any other way to cut an hole nice and clean on a curvy surface, that input would be most helpful as well!!!
thanks for your time!
