Hi, DEODR does not support multiple meshes at the moment. This is in the "to do" list. In the mean time you will have to pose each mesh and combine them into a single mesh before you add it to the scene. To do that you will have to concatenate the vertices and the faces array (you will have to add a constant to the second mesh face indices corresponding to the number of vertices in the first mesh). The trickier part is to back-propagate gradients to the original meshes and poses If you want to use the the gradients to fit the meshes to an image.
