Problem when Converting Polygon to Subdiv

[hunter204]

Good Day DT People, I have a problem when I convert an object from polygon to Subdiv. The object is not shaded but the other is shaded. How to back it to normal? what would I click or do? thanks in advance

Any Maya Expert knows the solution? I have attached the picture in the attachements to see what I am talking about.

Some times when the conversion from poly to sub-d fails these are the issues to check .

Some normals may be reversed .

Some polys may not be 4 sided so check for deformed polys eg polys with 3 sides or 5 sides ..

Thanks for the response bravo.. so what should I do to back it to normal and will be shaded?

I would say you should try to reverse the normals.

[bravo2zero]

there is a tool available to show normal direction they should all point out . if one dose not point out reverse the normal on that face only . Don't try to reverse all normals .

I ran into this issue several times too.

It isn´t necessarily that the normals are reversed. Sometimes Maya just removes the assigned material.
So if you assign your material on the mesh again it should be fine - but you can always check your normals too.

Thanks@ Golani'79 I had the same issue.
