Resolution group
Use these controls to change the vertex count and
overall topology of the modified object.
Vert Percent—The modified object’s vertex count
as a percentage of the overall number of vert ices in
the orig inal mesh. Adjusting this setting alters the
Ve r t C o u nt v a lue a s w e l l .
Note: Af ter you enter a specific percentage, such as
30, you might find that the software changes the
value to a slig htly lower one, such as 29.971. This is
due to the relationship between the overall number
of vertices in the model and the percentage
calculation. It is not a bug, but simply the closest
solution to your request.
Vert Count—The total number of vertices in
the modified object. Use this control to set the
maximum number of vertices in the output mesh.

as well.
Max Vertex—Displays the ver tex count from the
original mesh that you applied MultiRes to. You
cannot enter values larger than t his in the Vert
Count field.
Face Count—Displays the current face count. As
you adjust the Ve r t Pe rcent / Ve r t C o unt settings, the
valueforthefacecountwillupdateonthefly.
Max Face—Displays the maximum face count.
Generation Parameters group
Vertex Merging—When on, lets MultiRes merge
ver tices between discrete elements (page 3–933)
in a model.
For example, if you apply MultiRes to a teapot,
which comprises four separate elements, and
turn on Ver tex Merging , as you adjust the vertex
resolution, the separate components will meld
together into one contiguous lower-resolution
object.
To control Vertex Merging, you c an set a Merge
Threshold. This value determines the unit distance
within which vertices will merge at a higher rate.
Threshold—Sets the maximum distance in
3ds Max units between vertices in order for those
ver t ices to be considered for merging. Within this
distance, the vertices between elements are welded
together at a higher rate as the mesh is reduced in
complexity. Available only when Vertex Merging
is on.
Note: To eliminate only coincident vertices, set
Thresholdto0.0.ThisissimilartotheWeldVertex
function.
Within M esh—When on, MultiRes merges the
boundaries of adjacent elements and vertices
w ithin elements. Many objects can contain
multiple groups of vertices that don’t share
connectivity.AsimpleexampleofthisistheTeap ot
