I am trying to use the Remesh Modifier to reduce the number of polygons in a hemisphere shape (and simultaneously convert the tris to quads), as shown in the Blender page on the topic here. Note how the outer dimensions of the cone stay roughly constant as the Octree Depth increases (Original on left, then increasing Octree Depth from left to right).
However, when I try to use it, it drastically changes the outer dimensions of the hemisphere, such that it only keeps the top section of the hemisphere, as shown in the series of images below. Note how the hemisphere height decreases as the Octree Depth decreases.
Why is this? Note: I am using Blender v2.66 (released 2013), which may be the cause.
