Looking for Pointers in scanning

[ccobra]

I'm trying to find a lazy way to scan models that would be successful. So far it has been hit and miss for me with some working and some not. For example my current challenge looked ok to me after the scan and combining mode:

but then after doing the conversion I get the blob:

Any suggestions?

Definitely watch the video. As explained, photogrammetry is still not the best way to create a model. It's OK for organic objects, things that are "bumpy", but not so much for the clean lines of things like cars. If it's a model car, then you'll want to prep it with a matte paint job or something, because shiny things don't work well. In the end, you'll probably need to spend a lot of time tweaking it, anyway.

I was sent a super high resolution professional scan of a famous race car to play around with. It was essentially only useful to serve as a digital "body buck" on which I retopologized from scratch snapping my model to the surface of the scan. It was much faster than trying to correct all the problems inherent with scanning shiny metal and glass objects. My new mesh followed the flow and panel lines of the car, making it much smoother and much easier to edit, modify, and scale as needed to get it down to 1/64th scale. Scanning is just not that good yet for generating reliable meshes. Especially if you're scanning a small object. The percent error is far too great. Here's a side-by-side comparison of a scan vs. retopo/redrawn mesh...

CCobra, have a look at Meshmixer software for scan repair. I have had some success filling holes and repairing bumps. It’s free and you sculpt with too.
