Well, as things were left yesterday, I had a problem with how the model appeared under lighting, with ugly shadows on some faces, etc. I’m happy to say a solution was found. And so into today’s post…
The first problem I felt was the mesh I was working with. As you can remember I had used some bezier curves to create an outline, then mirrored it. The result of building the mesh this was far, far less than optimal for a good mesh, lots of vertices around the edge, and almost none in the center. So I decided to try again, just using the bezier for the outline, and building the inner mesh by hand.
As you can see above, I simply added a T shaped line of vertices in the center, so that i could build a basic grid across the whole surface. I then used standard ‘wagon wheels’ on the rounded corners. When I was done placing vertices and edges, It came out something like this:
You don’t have to go too crazy putting in every edge, as blender can auto-fill once you have the basics in place. but, it’s good to try to keep things square, and not get too dense. After doing a Beauty Fill on what I had built, I had a pretty decent mesh to work with. But there were a couple of things to correct, for the sake of perfection.
The two areas at the top were denser than they needed to be, and in the center, some faces split the wrong way. Nothing hard to fix. Few edits and it’s done:
So now we are ready to do all the stuff I did yesterday, again. The result looked a lot better, but still had some shading issues. But after some reading I found the second part of the solution, a technique called Edge Splitting. Basically what happens is, when you specify a mesh piece to be ‘smooth’, it will try to smooth it around very acute angles, and that results in shading problems. Edge split basically cuts the mesh apart at any seams above a threshold value, so this doesn’t occur. Works great. Here was the final result:
While I got the shape down, finally, I’m still not satisfied. It’s missing something. Oh yeah, in real life, they would never leave raw edges like that on a piece of leather… Lets put some piping on it.
Now we’re talking! I think we are ready to move on to the front piece. After all of this, should go smoother… (no pun intended)
