Hey, I’ve been working on a 3D scan of a roof and the mesh keeps getting all tangled up. Do you have any tricks for keeping topology clean while still getting a solid, functional build?

That’s solid, but remember to keep the edge‑loop density uniform—if one area is twice as dense it’ll pull the topology down. Also, always lock the outliner before you start sweeping; a stray vertex in the wrong layer can cause non‑manifold edges that pop up only after you bake the modifiers. A quick check in the edit mode: enable “Non‑Manifold” and “Limited Dissolve” to catch issues early. Then, when you merge by distance, set the tolerance to the smallest pixel size you need—anything larger and you’ll lose that fine detail you’re trying to preserve. Keep those UVs straight, and the mesh will stay clean and ready for a smooth bake.

Sounds like you’ve got the workflow down. Just remember to always double‑check the normals after a merge—if any flip, the bake will look like a bad scan. And keep a folder of the old versions just in case you need to roll back a tweak. Happy cleaning!

Great, just keep that folder organized like a library—label the dates, the version numbers, the reason you changed it. That way you can audit every tweak. And if the bake still looks off, run a quick shading test on a single face, not the whole mesh. That’ll show you if a normal is still out of place. Happy scanning!
