This window is opened when selecting the option box of the
Create BCS menu item in the New BCS
menu. Here, the options for creating new bcs nodes are specified. See below
for a description of each option.
Click an item on the image to jump to its description.
Stores the currently specified options, so that they are used on the next
calls of the Create BCS menu item. This is done
automatically when you click on the Create or
Resets the settings to their defaults.
Specifies the envelope of the new bcs node. This is a common attribute of
deformer nodes and specifies how much influence they should have on the
geometry. It should usually be left at the default of 1.
The new BCS node will deform the last selected object and add the other
objects as dataPoints. If this box is checked (the default), each dataPoint
gets a weight and a weightPosition. This will create a basic setup that is
equal to a usual Blend Shape setup.
Specifies whether to check the selected object’s names and create
bilateral weights for them when they match the entered pattern. If you’re
not familiar with match patterns, just don’t use this option and make your
weights bilateral after the node has been created. This can e.g., be done
in the weight settings box. If Check Falloff Number
is on, the first number in the matching part of a bilateral object name is
used to choose the falloff. Falloff indices are 0-based.
Specifies whether to check for a series of objects that belong to one
weight. This is done by removing the matching part of the entered pattern
and checking whether several objects have the same name after this. The
dataPoints that are collected for one weight are sorted based on their
name and equally distributed on positions between 0 and 1, the last being
at position 1. If one of the objects has the weight’s main name (when it
doesn’t match the pattern), it will not be sorted into the other
dataPoints but be placed at position 1.
Use this drop-down menu to specify the placement of the BCS deformer node in
the deformed object’s history.
Typically places the BCS node immediately before the current final shape node.
Places the BCS node immediately before the current final shape node.
Default and Before typically provide the same placement.
Places the BCS node immediately after the current final shape node, and
creates a new final shape node.
Splits the input deformation history into two separate deformation chains,
providing two final shapes originating from the same deformable object.
Creates a final shape that blends the object’s current input history in
parallel with the new BCS deformer node.
Front Of Chain
Places the BCS node in front of all the deformer and skinning nodes in the
deformable object’s history. (Recommended!)
Unless you know exactly what will happen otherwise, you should always use
Front Of Chain as the deformation order.
As previously stated, the BCS has to do quite extensive updating of
internal data every time the input data of the base object changes. You
should therefore avoid a situation where this could happen regularly, as
is the case when there are deformer nodes (e.g. skinning, clusters) in the
history before the BCS. If you choose Front Of Chain as the
deformation order, the BCS will become the first deformer and input
changes are less likely.
One remaining problem is that input changes are triggered in many cases,
even though nothing has actually changed—at least nothing of concern for
the BCS. To suppress any of these extensive updating processes of the base
geometry, use the Freeze Input option. Please refer to
the Freeze Input description for more information.
The Create button creates a new bcs node with the entered settings
and closes this window. The Apply button does the same but keeps the
