Hi redth,
Your requirement for independently moving goalie pads makes it useful to inspect the existing armature before estimating the full job.
My published examples cover environment assets and UI. I have no hockey character rigging example. My workflow would use AI-assisted Blender/Python scripting. Would you be open to a small paid technical test on one sample FBX before deciding on the full commission?
If so, which Unity version and rig/animation setup are you targeting, what should the first test demonstrate, and what budget do you have in mind?
The full scope and price would be confirmed after inspecting the sample. I would first establish whether the existing model can meet your requirements.
