A Blender Addon to help you keep your meshes clean and lint-free, like a spell-checker for your meshes.
Can check for:
- Tris: Evil.
- Ngons: Also pretty bad.
- Nonmanifold Elements: Stray Verts and Edges that have < or > than 2 faces.
- Interior Faces: Faces spanning inside the mesh that cause confusing effects with Subsurf and Edge Loops. By the Blender definition, this is only true for a face if absolutely none of its edges are connected to <= 2 faces.
- 6+-Poles: Verts with 6 or more edges (check disabled by default, because some mechanical meshes legitimately have this).
- ...can you think of more? We'll add them!
So if you click Select Lint, in Object or Edit Modes, it will set your
current selection to all elements that fail the enabled checks. A good thing
to do if you are having trouble finding pieces is to hit Numpad '.', which
will center the 3D Viewport on the problems. You might have to do this
iteratively with border selects and Middle Mouse Button to deselect the
elements you already know about.
Also, you can enable Continuous Check, which is a huge aspect to this. It is
good for cases where you think you won't be creating any new problem geometry.
Whenever something goes wrong, the Info Bar at the top will display a message
describing what MeshLint found. Also, you will notice the counts are updated.
To install...
Hit Ctrl+Alt+u to load up the User Preferences (I always use the keystroke
for this because of the occasional time where you miss, using the File menu,
and click Save User Settings. Click the Install Addon... button at the
bottom, then navigate to your meshlint.py script.
Next, and this is a tricky bit, if you're not used to installing Addons: you
have to follow up by checking this little box on the right of the Addon entry
in the list. If, for some reason, you have a hard time finding it, you can
search for MeshLint or click on the Mesh button on the left. Hopefully,
though, it comes right up when you do Install Addon....
If you want to keep MeshLint available (and who wouldn't?), follow the above
steps on a fresh .blend (one you Ctrl+nd), then hit Ctrl+u at this
point. The next time you run Blender you won't have to repeat the above.
When installed, it will add a new Subpanel to the bottom of the Object Data
properties (the button in the Properties Editor that looks like the inverted
triangle).
We really want to make this a top-grade Addon. This will take a bit of debugging and brainstorming, both. There's a spot right below this text for a "Thanks", for Blenderers who give such feedback.
