I wanted to make an addon that includes a model (Tank) to ride a bicycle, with custom animations. But first I only went to adding the bicycle prop to the model of the Tank. The bike is a single mesh as I already joined the parts. I also reduced the polygon count on the bike.

my goals being:

• The bike is attached and follows the tank
  
• Able to transform and animate the bike individually so I can adjust it with the Tank's animations
  
• Also able to custom animate the tank

One of the things I did while experimenting was giving the bike mesh an armature inside the seat then parenting that to the Tank, I placed the bike near the pelvis (Preview). It works and follows the tank when I played the animations.

The problems arise during compiling it in Crowbar. Most errors I get are actually after compiling it but the model viewer can't load it due to an error. It's probably because I didn't edit the QC files.

I have questions for the process.

1. Where do I parent the bike armament to what Tank model
In the Scene Collection display of Blender, the Tank has:

tank_reference
tank_reference_lod 1
tank_reference_lod2
hulk_physics
hulk.qc_skeleton


2. What do I edit inside the QC files of the tank (hulk.qc , anim_hulk.qc) after I exported it using Blender Source Tools.

3. Do I also have to export every animation one by one of the tank? Do I have to do this for the bike as well (It doesn't have animation yet, It's just attached to the model)

Any help is appreciated.

Would also like to ask for the proper workflow for what I'm doing and corrections on things I probably did wrong.
