As comrade @Yinkle said, if there are no necessary bones in the meshes, then nothing will work out. And to add these bones you need to be able to work in 3D programs. If there is an interest in SMP physics, it is easier to start with ready-made HDT PE models. When there are already ready-made bones to provide physics and you just need to teach them to move correctly within the framework of the SMP framework, write the correct xml file, learn how to model movement dynamics using those operators that the framework provides. Mass, inertia, springiness, damping, taking into account the weights of bones, the position of bones in space, the restriction of their movement alone or in an array. The next step is to understand how to configure the interaction of meshes in the turning world and between themselves, that is, collisions.
