mcmotanal utility

Converts a Motion Analysis TRC motion file to a Houdini script and channel file(s).

Description

Converts a Motion Analysis TRC motion file to a Houdini script and channel file(s). You can then run the generated script to create the geometry and channels.

Options

-e

Stuff parameters with expressions (chop). If you don’t specify -e, -b, or -d, this is the default.

-b

Leave parameters blank.

-d

Leave parameters blank and override the created channels.

-c

Only create the channel file(s), not the script.

-j script

Set the object creation script (adds opadd geo script to the generated script).

-o

Create character using object joints.

-w

Create character using object joints and wire polygons.

-f

Create character using forward kinematics (FK). This is the default.

-i

Create character using inverse kinematics (IK).

When you specify -f (forward kinematics) or -i (inverse kinematics), the following option is available:

-n num

Specify a bone length channel type: 0 for none, 1 for always, or 2 for auto.

When you specify -i (inverse kinematics), the following options are available:

-t

Create dual bone chains with twist affectors.

-l chainfile

Specify a file containing a list of bone chains.

Each line of the file must be in the form:

<IK chain root joint> <IK chain end affector>
