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 vertices in
the original mesh. Adjusting this setting alters the
Ve r t C o u nt v a l u e a s w e l l .
Note: After you enter a specific percentage, such as
30, you mig ht find that the software changes the
value to a slightly 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.
AdjustingthissettingalterstheVertPercentvalue
as well.
Max Vertex—Displays the vertex count from the
original mesh that you applied MultiRes to. You
cannot enter values larger than this in the Vert
Count field.
Face Count—Displays the current face count. As
you adjust the
Ve r t Pe r c e nt / Ve r t Cou n t settings,
the value for the face count will update on the fly.
Max Face—Displays the maximum face count.
Generation Paramete rs group
Vertex Merging—When on, lets MultiRes merge
ver tices between discrete
elements (page 3–1027)
in a model.
For example, if you apply MultiRes to a teapot,
which comprises four separate elements, and
turn on Ve rtex Merging, as you adjust the vertex
resolution, the separate components will meld
together into one contiguous lower-resolution
object.
To cont rol Vertex Merging, you c an set a Merge
Threshold. This value determines the unit distance
within which vertices will merge at a higher rat e.
Threshold—Sets the maximum distance in
3ds Max units between vertices in order for those
ver t ices to b e 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 Mesh—When on, MultiRes merges the
boundaries of adjacent elements and vertices
w ithin elements. Many objects can cont ain
multiple groups of vertices that don’t share
connectivity. A simple example of this is the
