Rig wont move, only bones (BLENDER)

Basiclly im in pose mode trying to model, only the bones will move not the arm, I did everything the tutorials said and looked into it, might be the view model? any solutions or got a better view model?


Umm you gotta make the specific part as the parent of the bone, assuming that you rigged it yourself you probably forgot that step.

Did you use the Blender rig exporter/animation importer?
