Building a custom rig !!!
For animating purposes and the use of
character studio this character will need to have its own custom rig built to
match the mesh.
What a rig basically its the bones in which
the custom mesh is attached or skinned to so that its easier to animate with
the bones instead of having to animates through polygons.
To build a rig the user must first go into
CAT objects and drag out a CAT Parent. Once this is done the user can begin
building their bones and the starting point would be a pelvis. Once the pelvis
has been created it is placed just above the waist of the human mesh.
Now its time to add legs which can easily
be done by selecting the add leg button on the rig options. a leg will appear
and it needs to dragged and put into place and rule number one when creating
the rig is to have it matching as much as possible to the mesh because this
will help hugely when completing a
stress test.
Once the leg is in place to make the second
one, Add leg should be selected again and the leg in which was edited to math
the mesh will be mirrored over and should need none or minor adjustment to
match the other leg. Moving on the next step would be to select the pelvis
again and this time select add spine. This option creates a spine above the pelvis
and can be updated to match the mesh and the amount of bones in the spine can
be adjusted in the editing tools in the rig options panel.
Next step would be o creates the arm this
can be done by selecting the top bone of the spine and selecting add arm to it
and an arm should appear and be attached ready to the spine or shoulders. Then again
just some adjustments need to be conducted so the bones match the bones and
once one arm is complete by pressing add arm again this arm should be mirrored
across to the other side of the body. One thing about the arms is that if the
mesh has fingers the bones can be added by inputting the number of bones
required on the palm of the hand and not by pressing add bone.
After completing the arms and fingers the
final step would be to add the neck and head which isn’t very difficult. If the
user was to select the top of the spine or shoulders the user may add another spine
with fewer bones and re adjust it to match the head mesh.
This would mean that rig creating is
complete. Some advise from personal experience is that make sure the bones
match the rig in size and width because it will prove a challenge when skinning
has to be applied. This is because certain bones wont attach to the mesh that
will mean the movements wont look very smooth and further editing will have to
be done.
