I don't have ASP 11 on my laptop to check but I don't think it's possible to use bones with a 3D object in ASP 11. For that matter, I don't think Moho Pro 12 or 13 can eitherI
And even if you could, ASP/Moho's bones work only in 2D space so the deformation options will be limited. IMO, it's better to do this in a 3D animation program. You can import a 2D rendering to ASP/Moho from the 3D program, if you like. (I sometimes do this for '3D' props I want to use bones on or to get a particular look with a character.)
Re: binding 2D, If you've imported a render of the 3D object from another 3D program, or you've rendered a 3D object in Moho and imported the rendering, you can rig that 2D image with bones just like any image layer in ASP/Moho. It will use Flexi-binding by default.
If you want smoother deformations or more explicit bone binding for the image, you'll need to use Moho Pro 12 or higher so you can create a custom mesh to deform the 2D render. Once you have your mesh, you can use flexi-binding or point binding with the mesh.
Tip: hayasidist's Bake Layers to PNG script can be useful here. It doesn't work directly with 3D layers but it you put the 3D layer in a group, you can run the script on the group. After the baked layer is created, you can do this to it:
Hope this helps.
