Modifying and Controlling 3D Model Components

Photoshop can move Obj files around inside a 3D scene, it can also merge all (some) of the different Obj files together or cut them up into smaller parts & you do all of this from the 3D panel

now for fine control of the mesh you need another software like Fuse, Wrap3.3, Blender or Maya but that is not needed to move, merge or cut Objs

please show us a screengrab of your 3D panel so we can see the parts

No, there isn't. PS isn't a 3D modeling app and there is no way to select polygons, vertices and so on individually nor is there a function to just split non-contiguous meshes. You have to move on to greener pastures, i.e. a proper 3D program like the free Blender.

if you opened it in Photoshop then its prob a Obj file so yes you can move them together... show us your 3D panel please

Hi i dont think there is such option in Photoshop because its main purpose is for texturing but if you import single objects like layers work in Photoshop may be it can help...Regards
