Hi ,as a newbie to Blender, i am following a tutorial to export Rigify to Unity, Im following the tutorial by AlexLemminG and using his add on ( RigifytoUnity ) However the part where you press ctrl P and then Armature Deform automatic weights. But my mesh explodes !!! Anyone know why ?
When attaching a model to a rig, it must be in a neutral pose, either A pose or T pose
That parts been done T pose ect, Im trying to export my anims into Unity
I’m going to repeat myself with an addition which may help- when attaching a model to a rig (pressing Ctrl P and choosing Automatic Weights), the model must be in a neutral pose, either A pose or T pose
Your first screenshot suggest otherwise.
Have you done your animations with a different rig, and then trying to parent the model into a new rig? Because your character is obviously in posed position when you are trying to parent it to the rig now. That won’t work. If that’s what you want to do, and as you are a beginner, I recommend saving a backup copy of the blend file. After that you must clear all poses from the character, unparent it from the previous armature, remove all vertex groups, then clear all poses from the new rig, switch to dope sheet and choose action editor, and unlink action (make sure you first click fake user button to not loose the animation), then do parenting with automatic weights, then add the action again.
Actually, from the outliner it seems that your character is already parented to the armature! 
(it’s under the armature in the hierarchy) So you don’t need to do that any more. You can just skip that part.
(edit: in theory, the character could still get the deformation from another armature than from what it is a child of, so go into the modifiers tab and make sure that the armature modifier has the correct armature set in the settings.)
Ah I think I understand what you mean now, in the object mode he has to be in the T pose. coming from a Maya background, Im still getting used to this pose mode object mode . I will give it another try now, Thank you
I think you may well be right, i will skip it and see how it goes.Thank you
