The shifter_classic_components from mgear-dev

Add UniScale option for games compatible

add option to use uniform scaling in squash and stretch operator.

shifter_classic_components: mouth_01: need configuration settings

now the default behavior is hard-coded and only editable after build the component

Shifter_classic_components: control_01 component maximum scale is too small.

From @Ruuttu : mgear-dev/mgear_legacy#245
we're making a ridiculously large character and the maximum scale of 200 for controls isn't enough. Part of the problem is we're using centimeters for units, so a ten meter character is already 1000 units. I'd like to bump the maximum scale to 2000 since there shouldn't be any harm in doing so.

Shifter: Component: Gradual scaling on legs and arms

From @miquelcampos on January 31, 2018 9:46

Add a gradient/gradual linear scaling for arm_and leg 2 bones. Similar to ms components

shifter_classic_components: chain_net_01: improve pickwalk

Shifter: Control_01: Expose more space switch options

From @miquelcampos on December 11, 2017 23:48

Add an option to configure the space switch to work with rotation, translation, scale or any combination

Shifter: arm_2jnt_01 and leg_2jnt_01: Make optional the extra support joint in the articulations

From @miquelcampos on May 4, 2018 1:44

default configuration have to extra jnt in knee and elbow to support better deformation. However this behavior can be undesired in certain situations. Make this optional

The central joint will change the behavior to rotate 100% with the forearm or lower leg. So can be use as a reference rotation point for game engines .
the default behavior for this joint is to rotate 50%

shifter_classic_components: New Component: chain_net_01

Create a dense net of IK controls driven by a few n number of chains

shifter_classic_components: issue with arm 2jnt_freeTangents & leg 2jnt_freeTangents

Orientation of deformers in both 2jnt_freeTangents & leg 2jnt_freeTangents seems to be strange, very hard to get good results when skinning.(see example attached)

update UI for leg and arm to support new game options

-Support joints
-Division can set to 0

arm_ms_2jnt_01 fcurve building issue

Need to apply the same fixes to this component for the fcurve divisions thing

Shifter: leg_2jnt_01 locket attr issue

Similar to Spine IK but FK controls are Master and IK slave.

shifter_classic_components: New Component: Whip chain

shifter_classic_components: Eye component update structure

in order to inherit correctly a non uniform scaling from the eye over control. Eye structure should be under eye control, and some constraints should be removed.

shifter_classic_components: Spine FK: fisrt joint moving with IK chest control

the position in the path should be 0.
Just need to comment out 2 lines. Since this component was started from previous IK version still have some lines that are not needed

Shifter: leg_3jnt_01 joint flipping problem

From @Lohult on August 5, 2018 12:42

Hi Miquel,

I have discovered a bit of a flipping problem with the leg_3jnt_01 component.

The leg component has joints ranging from leg_L0_0_jnt through to leg_L0_9_jnt followed by leg_L0_end_jnt.

The flipping occurs when rotating leg_L0_ik_ctl in positive X. 91.068 is the exact number where the flip occurs (the guide is kept in default arrangement for the test).

At 91.068 rotation X on the IK control leg_L0_9_jnt and leg_L0_end_jnt flips from zero to -180. When skinning to these joints it becomes quite obvious when the flipping occurs.

My use case is a cat leg and the IK controller get rotated to curl the paw while walking for example.

Shifter: Components using profile curves create division by zero issue with impair division values

Issue

When using impair subdivisions values on the neck component this causes the middle stretch values on root to be 1 and this been causes the division by zero later on.

shifter_classic_components: New Component: Tangent_spline_01

Component to create tails and low body like Medussa character style

Shifter: Neck_Fk Component

From @miquelcampos on November 15, 2017 4:36

New Neck with priority on the FK controls. The IK will be a supplementary control.

Copied from original issue: mgear-dev/mgear_legacy#97

components using FcurveParamDef needs to be update to store to dict

all components using FCurveParamDef needs to be updated in order to be exportable

shifter_classic_components: FreeTangent Limbs Round-Feature Issue

Reported in the forum: http://forum.mgear-framework.com/t/3-0-5-freetangent-limbs-round-feature-issue/516

it seems that when creating a “leg_2jnt_freeTangents_01” or “arm_2jnt_freeTangents_01”, when using “Mirror Mid Ctl and UPV axis” option in the settings, the right side limbs break when activating the “Round” Feature on the rig.

shifter_classic_components: New Component: chain_IK_with_variable FK and stack connection

same as IK with variable FK but with stack connection

Shifter Components: if support Joint parameter is missing update guide will fail

Components leg_2jnt_01 and arm_2jnt_01 are affected

Shifter: Create new distribution structure

leg_2jnt_freeTangents_ and leg_ms fcurve building issue

Same goes on this two guys as for getting the fcurve divisions

Shifter_classic_components: new arm and leg with elbow and knee thickness control

A new variant of the default components in the biped template to support thickness in the articulations

arm_2jnt_03
leg_2jnt_02

arm_C0_fk0_ctl on the arm_ms_2jnt_01 component has incorect reset values

Seems like the first FK control on the arm does not get correctly reset when been build.
(http://forum.mgear-framework.com/t/arm-c0-fk0-ctl-rotation-has-values/269)

Shifter_classic_components: leg_2jnt and amr_2jn precision error sets division position to 1

The division position on the rollSpline solver should not be 1.0 or 0.0
Because the division will lose the tangent orientation in the spline. need to be max 0.999 or min 0.001

shifter_classic_components: Lite_chain_01: add option to build without joints

In some situations the lite_chain_01 is used to drive other chains so joints are not needed

shifter_classic_components: New Component: shoulder_02

this new shoulder have 3 position in order to decouple the shoulder FK control and the orbir control position

Shifter: Foot component: Have some orientation limitations

From @miquelcampos on April 11, 2018 14:8

At this time,
we have to model certain limbs at fixed orientaons
as far as legs goes and such,
otherwise the foot roll solvers will be slanted and FKs's not oriented to they would be expected
to be. We cannot generate a viable rig if someone has legs at any angle that is not aiming
directly at the go

shifter_classic_components: New Component: Chain FK spline with variable IK controls

similar to previous chain FK spline but with the option to set independently the number of IK controls

shifter_classic_components: chain FK with variable IK the extreme controls should not be on 0 or 1.0 of the path

the path percentage should be limited to the value .001 and .999 so the control moves with the curve tangent

leg_3jnt_01 fcurve values issue when building

Do to the changes been brought to mgear-dev/shifter#26 this shifter components needs to be updated

shifter_classic_components: add new upv roll control to arm_2jnt

The request is to have something similar to this example:

shifter_classic_components: Review channel hosts for stack connection chains

we need better managment for the channel controls
Specially the show/hide IK and FK controls are hard to manage

Shifter: Leg IK controls world orientation should be optional

Make optional the way the IK control in the foot is oriented.
This should apply to all the leg components

http://forum.mgear-framework.com/t/problem-leg-ik-orientation/173

shifter_classic_components: New Component: Chain IK spline with variable FK controls

similar to Chain FK spline with variable IK controls , but here the IK is master and the FK slave (like spine IK)

shifter_classic_components: new component: Lite chain stack

a lighter version for chain stack

arm_2jnt_freeTangents_01 fcurve building issue

Need to apply the same fixes to this component for the fcurve divisions thing

shifter_classic_components: New Component: Hair Stack Chain

Special chain component for hair

this component can be stack in order to control several chains (slaves) with one master chain
the connection can be using local axis or world align
the Master chain should have at less same segments as the biggest of the slaves. But the slaves can have same or less
Tip and mid control twist, and scale (wide and depth)

Shifter: leg_3jnt_01 Ik connector place the child components under a hidden Joint

shifter_classic_components: issue with arm 2jnt_01

There seems to be an issue with the orientation of the arm_R0_jnt (the first joint of the right arm component) when the roundness attribute is used.
The left arm seems fine but this issue happens on the biped guide or If I create a new arm 2jnt_01 component.(see attached image

)
