poissonrecon - cloud to mesh

Good Day

I am trying to make a mesh from a point cloud.

I have combined all the scans and also subsampled it, when I run the Poissonrecon I get this result:

Any advice on how to make it work, and if it is even possible?

Thank you

I would guess that there's an issue with how the normals are oriented. How have you computed them?

Another suggestion which might help is, whenever I use Poisson Reconstruction I always turn on the option to output density, then I filter the resulting mesh to remove regions with low point density. Even if the normals are good it often extrapolates surfaces where I don't want them.
