-      <p>This option controls how many points (rendered as spherical meshes) are put into each mesh in the export glTF file. Setting this value lower will result in a smaller file due to how the glTF is created, but may negatively impact performance as it will requires more draw calls inside the renderer.</p>

       <h5>Resolution</h5>
       <p>For vispy scatter layers, each point is rendered as a spherical mesh. In the output model, we allow setting the resolution of these spherical meshes. Increasing this value leads to a higher-resolution mesh (closer to a sphere), but will increase the filesize, as the spherical geometries now have more points and triangles.</p>
       <p>For ipyvolume scatter layers, where each layer uses a glyph with a definite geometry, we simply replicate the geometry of the relevant glyph.</p>
