Hello, anyone knows how to prevent or how to correct this kind of aberration in face scan, please?
I’m using an Inspire 2
Hi @Ambrogio
I give you a reply regarding this issue in another thread you created.
Please clean it after fusing by removing overlapped points and lose points , then you can mesh it . If the point cloud is not clean , you going to have overlapped skin issues like that.
Even slightly micro movements of the face can create artifacts so advice your model to breathe slowly .
thank you, I’ll try right away
The correction is going poorly, it shows that I have a “double surface” of data points in the area that gives that aberration. I would love to be able to select the “under” surface and delete it, but in the point view I’m unable to distinguish it, and in the mesh view i can only interact with the “outer” surface.
Is there maybe a good way to clean this or correct this in post, with blender?
Try the sculpt tool in Blender, and use the smooth tool. Make sure you enable Dyntopo to allow for more geometry to be created to help fix this kind of problem.
I hope this helps.
Will try, thanks!
I am not using blender and this kind of artifacts are very hard to be removed because they are double wall artifacts , you can’t smooth it out .
They need to be cut out and the hole need to be closed using Closing Hole and curved option .
You can try to use the tool on the right side , it looks like a donut , try to select with it the other shell then reverse the selection and delete , it may help if the both parts are not connected .
You have also options to select the top or under side normals by switching the selection , it is in the right side where are the tools . It allows you to select all points that are reversed and eliminate it .
If not working for you , try to cut it out after fusing, and fill the holes after meshing .
You can also use Raw Edit option to remove the bad frames before fusing .
Hi Tom, this kind of artifacts can’t be smoothed out . It is double wall artifacts , they need to be removed manually , cut out , raw frame edit etc .
This does work if you use dynamic topology. I have done it this way many times. Works well in Nomad Sculpt too. Big complex ‘pipes’ from poisson surfacing don’t clean up so well.
Yes I would use Zbrush for that kind of work and workflow as well , but trying to explain what it really is , as it is deeper than just surface imperfection so regular smoothing brush can’t fix it .
