blender - rigging/skinning problems

    Hi all

    I'm new on here, so bear with me...

    I have had some trouble over the past few days with a model I created for a college project.

    The model itself is ok, but when I created the armature and went into pose mode to move the models limbs about the following happens.

    I have inverse kinematics applied to the lower bone in the legs and the bone in the hands, as the online tutorial specified.

    I have also got sub division surface applied to the model.

    Any help would be brilliant, as I have posed this question on the blender.org and blender artists forums with little or no response.

    I have also tried weight painting the model with the same result.

    How have you connected those head components together?

    I am assuming so. I was following this tutorial online

    Have a read of this more simple tutorial and see how it compare to what you're doing:
    http://wiki.blender.org/index.php/Doc:2.6/Manual/Your_First_Animation/2.Animating_the_Gingerbread_Man
    I don't do enough with blender, especially rigging and skinning to tell you exactly what's going on, but it does look like there's something funky with the head mesh. It looks similar to the issue that the guy in the video has with the hand at 6.02.

    Can you attach/upload your blend file?

    this is today's version in zip format, the same thing happened again.

    their are extra bones within the mesh (I thought it may help) and Inverse Kinematics applied.

    and thanks in advance for any advise on how to rectify this.

    Dude, your model is a bit of a mess. Your limbs intersect with the body making it impossible for the IK solver to apply weights to the limbs only. I've attached a simple example, as you can see the arms are outstretched to the sides to make them easier to pose.

    Try to make a cleaner model with stretched out limbs away from the body. For an accurate Lego man you don't need to use IK, just hook the rigid components together.

    will give that a try, much appreciated.

    Hi I tried outstretching the arms and still no joy... it is still leaving vertices behind...

    I have re attached a file.

    Then you need to add weights manually.

    Why do you have so many bones in the hands? There's no need. Try to keep it simple before you ramp up the complexity. Try skinning a single tentacle for example, then do the gingerbread man tutorial.
