I have modeled this stairs for a house patio.. but I don't know how to create a clean topology for the top of the stairs.. all I need is a plane area, with quads, and I don't know how to create this area..
The area i'm talking about is the curved shape on top of the stairs..
This is the zip that contains the scene file: patio.zip.
Also, I need an help to the UV unwrapping of all the stairs..
As you can see, the UV are pretty messed up..
