Best way to clean up geometry from photogrammetry scan?

[cjzbc]

Hi, I’ve recently started using using ZBrush to improve my photogrammetry workflow (with Metashape). Until now I haven’t had any problems cleaning up artifacted geometry, but my latest scan has a fence which got very messy. I’ve tried to look for resources but I don’t think I know the terminology well enough to find what I need. What would be the best way to cut holes back into this fence where they have been filled and remove some of the messier parts of the geometry I haven’t been able to tame with my move/smooth/clay buildup basic tools?

Thanks in advance for any help!

Hello @cjzbc

I’m not sure that there’s anything there to really “clean up”. I think the best you could do here is to simply recreate everything using conventional mesh creation tools and use this as a reference.

However, to answer your question, Live Boolean could be used to interactively cut custom shapes into the fence.

Thanks for your response! The problem with that method is that the mesh needs to be exported back into Metashape to have the texture projected on. If I sculpt new geomtery I’m afraid it won’t work. My goal isn’t a perfect model just a less-messy version of my current one where i can zremesh and project/subdivide to bake UVs, normals and displacement maps for a low-poly model
