See I have this problem, I converted a Halo 4 Spartan Amour over from SFM to Blender. The model works great but the Armature itself is not so I decided to use Rigify to make a new one to replace it. The model is made of 7 Parts for customization:
- The Body itself minus head
- A helmet
- A chest piece of Armour
- Two shoulders (these are both separate)
- Arm Armour
- Leg Armour
I got the rigify armature acurate to the models body position and was able to parent the body as well with automatic weights but i do have some problems.
I can Parent with automatic weights with everything except two, the torso and leg armour. I receive the “bone heat weighting” error when I try to pair these objects to its respected bones.
I have linked the blend file for whoever wants to help try and fix this issue.
