It can be reduced by removing surface details and faking them instead. A normal map is similar to a texture map, but instead of being rendered in color, it is interpreted by the render engine as surface details that catch the light or cast shadows. text/html 2020-02-18T12:02:27+00:00 Anonymous (anonymous@undisclosed.example.com) http://www.formlab.schoolofarts.be/instructions/doku.php?id=3d_modeling:blender:clean_up_3d_scan&rev=1582027347&do=diff Clean up 3D scan Clean up glitches Sometimes a 3D scan has jagged protrusions. * Go to the sculpting workspace * select the 'Simplify' brush * Set autosmooth to 1 * enable 'Dyntopo' * Change the 'Refine Method' to 'Collapse Edges' * text/html 2021-10-13T10:07:20+00:00 Anonymous (anonymous@undisclosed.example.com) http://www.formlab.schoolofarts.be/instructions/doku.php?id=3d_modeling:blender:clean_up_occipital_3d_scan&rev=1634119640&do=diff Clean up a 3D scan made with the Occipital Structure scanner The 3D files from the Structure scanner often have holes and unwanted geometry.

Double tap G (vertex slide) and move the mouse a fair distance to one side. This moves all the selected vertices into one of their neighbouring ones, merging them automatically.

Each bone has a limited amount of influence on the 3D model and it pivots on one end, just like most of our bones do. This method of 'rigging' (creating a skeleton to animate your object) is super fast and easy. It has it's limitations, but it's good for simple poses and animations.

Add a plane. This will be the cutting plane. If you want to reorient it, only do so in 90 degree increments. This will make it easier to lay the models flat in the slicer application.
