CloudCompare forum

As far as I know, no one has done it (as this is an open source project, we can only rely on individual contributions).

I've never seen this error, but I personally don't use this plugin often. Is it occurring with a particular format/codec maybe?

The first thing you need to do is select/highlight the mesh entity (then all applicable options will become accessible).

This version fixes the issue normally: https://www.cloudcompare.org/release/Cl ... up_x64.exe (I cannot list it on the website as it's not signed sadly).

I'm not sure the plugin's author (Sam Thiele) visits the forum. Maybe you could send him a message directly (I believe his contact is on the plugin's Wiki page)

But another way might be to convert the textured mesh to a (very) dense point cloud? (with 'Edit > Mesh > Sample points')

For the 2nd and 3rd images: aren't the normal simply inverted? That would explain why you have a clean model in the end.

And have you tried the Minimum Spanning Tree algorithm to (try to) set the orientations in a more dynamic way?

Yes, you can rename the scalar fields between various runs of the M3C2 plugin (so that they are not overwritten).

Else if you really have multiple clouds (with the same point positions?) then you can also use the tool 'interpolate SF from another entity'. But mind that you will also have to rename ...

Yes, it's the last bootleg / rip-off version of CC that doesn't comply with the GPL license (see https://www.cloudcompare.org/release/notes/20240214/ at the end).

They never replied to my mails :|

Here is a fixed version: https://www.cloudcompare.org/release/Cl ... up_x64.exe

(sadly, it's a non-signed version as I have some issues with my certificate - you'll have to convince Windows that it's safe to run)

Can you test this new version: https://www.cloudcompare.org/release/Cl ... up_x64.exe

(sadly it's not signed with a certificate, so you may have to convince Windows that it's safe to run)
