Budgerigar Rigged VFX Grace 3D model

Introduction
These are two realistic 3D budgerigar models with multiple 4K maps, feathers and rigging. The rigging allows users to control every feather. The model is made with Blender and Cycles renderer.
The models consist of body, eyelids, films, pupils, irises, toes, tongue, body feathers, wing feathers and tail feathers.

Rigging
With fine rigging, postures and animations are easier to create, the features are as follows:
There are two sets of skeletons: one for the wings and one for the body.
CTR_Root_a and CTR_Root_b control the entire body, and are scalable.
CTR_Root_a has multiple customized attributes:

1. a_IKFK_leg.L and b_IKFK_leg.R control the non-seamless switch of IK/FK of the legs.
   
2. c_IK_Stretch_leg.L and d_IK_Stretch_leg.R control whether the legs can be stretched in IK mode.
   
3. e_IKFK_neck switches the IK/FK of the neck.
   
4. g_head_follow controls whether the head rotates following CTR_BackGravity.
   
5. h_CTR_Twich is to display/hide some small stretch controllers.
   
6. i_head_independent controls whether the neck rotates following the CTR_BackGravity in IK mode.
   
7. j_IK_neck_seldom is to display/hide infrequently used IK controllers of the neck.
   
8. k_wing_follow controls whether the wings rotate following CTR_BackGravity.
   
9. l_head_FollowRoot controls whether the neck rotates following CTR_Root_b in IK mode; when this is enabled, g_head_follow will be ignored.
   m_wing_FollowRoot controls whether the wings rotate following CTR_Root_a, when this is enabled, k_wing_follow will be ignored.
   CTR_right_wing_fold and CTR_left_wing_fold control the folding of the wings by Location.
   CTR_FeaTail_fold controls the extension and flexion of the feathers on the tail.
   The toes have fine controllers to make subtle movements.
   Each feather comes with skinned bones, FK controllers, detail controllers and bending controllers. Besides, there are some controllers which are to bend, rotate, fold multiple feathers overall.
   And more…
   

Features
The model is in meter units at real-world scale.
To run faster, the fur is hidden, with Render enabled.
There are no object that controls feather surface deformation in the attached FBX model.
To reset the initial pose of the model in JF0L811A6_Budgerigar_Couple_Fly_2.83.5, please set a_IKFK_leg.L/R under CTR_Root_a to 0, then press A to select all controllers, and press +G, +R, +S.
