Adding a plane in renderer

[santurini]

Hello, I would like to render a motion with pytorch3d renderer. My motion consists in a folder of .obj files, each containing a body mesh. I would like to place a plane mesh in the environment that has to be present in every frame. How can I achieve that?

Up to now I am able to obtain this results (no plane, just body mesh):

But instead I would like to have something like this (underlying plane):

You can construct the plane as a mesh with two triangles. Then each time you want to render the body mesh you will use pytorch3d.structures.join_meshes_as_scene to make a mesh of the body plus the plane and then you render that.
