I have just made some fusion tests with the 10 turntable scans from here:
viewtopic.php?f=6&t=4291

Only the fusion with a chosen resolution > 1000 closed the big hole below the base plate.

Walter, Sven,

Thanks for clearing that up. It is not a big problem,but maybe a tolerance variable setting can be added to David's advanced settings in the future? Something like close holes with diameters greater than x or something like that. Poisson at 1000 gives me rough meshes sometimes so that is not always an option.

Hi Tibor,

Clearly one or more of your scans is misaligned. Try isolating those scan and aligning it to one that has a lot of similar overlapping points. I haven't seen a problem aligning things normally with 3.9.0 beta2 yet. Did you align those using just One-Click Scan + Align? That will require a very small change of position between scans to work; You want the greatest amount of overlapping points between previous scan and the new one.

Hi Mattia,

Did you try upacking the beta to Program Files (x86) where the installer puts things or is it somewhere else? I have it on my desktop though and it works (Win7 Ultimate).

@ShadowTail:

You are right, I did not see that scan 7 also shows the feet.
Scan 2 and 7 are both used for the texture at the top of the feet. Mainly Scan 7 indeed, because the view is more orthogonal to the surface.
But both textures (2 and 7) are very dark there. In texture 7 there is a shadow line which mainly causes the problem. Please replace it with a new scan from similar direction, but without shadow line.

Deleting surface regions will not remove those areas from the texture.

Hi Bongobat
I have a set which includes the calibration, camera, laser, stepper motor, a software click 3.9.0beta2, I scanned object.
The second set which includes the calibration, camera, laser, stepper motor, software 3.8.1.377 manual adjustment.
The second set gives a good alignment. Unable to manually set first is well adjusted and not one click.
I want good results. Unfortunately, no one has published the images of slaughter and cleanup logic. Several times I have asked the forum members to help with this, I can not answer.

Hi Sven
I downloaded the terracotta soldiers. Invariably ask why the ripple. I have this big problem.!!!

Hi Tibor,
The ripple effect (waves) can have several possible causes. HARDWARE causes. Please post details about your hardware and a live camera image.
