Maya Bridge + Smooth/SubD

Maya 2020 fundamentals - modelling the real world

Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

Hi, I have a probleme with the subdiv, when I hit 3 on my keyboard or if I smooth my mesh within maya theres is strange topo artefacts that happen where I did a bridge on two edges.. My vertex are weld together and my normals are all facing in the same directions (outward). If I export my model to zbrush and re-import it, the artefacts are gone! Someone has an idea on whats happening and how to solve it?

Thanks!

Try using 'Soften Edges' in the normals menu.

When in doubt, delete history and freeze transformations.

The bridge tool may have set your face vertices to point directly forward, making the faces look like they are artificicicieded...

Import and export to and from Z kinda prooves it as the program will re evaluate the normals on import and hence when exported its fine.

Try BennyK's suggestion it should sort out the issues.

Yeah I tried soften edge, i do that each time I add new polys to my surface.

My normals seems to looks good.. no one is pointing inward the surface, but i'm steel getting the artifacts.?

Try setting the vertices to faces on the problem area and see if that helps.

Someone had tha same problem than me. He told me that he use append to polygon instaid. It solve my problem. I think it's a probleme with the bridge tool.

The poly bridge tool is only designed to bridge a gap between 2 edges...

Poly Append Tool is for filling in where there are missing or removed polys.. So i agree delete the problem faces and use polygon append
