how could i use pytorhch3d v0.2.5 to render face

❓ Questions on how to use PyTorch3D

     because you change the textures and my previous code could not work ,and i do not know how to fix my code to render the  face  can you give the example ?

NOTE: Please look at the existing list of Issues tagged with the label 'question](https://github.com/facebookresearch/pytorch3d/issues?q=label%3Aquestion) or ['how-to. Only open a new issue if you cannot find an answer there.

Also note the following:

1. If you encountered any errors or unexpected issues while using PyTorch3D and need help resolving them,
   please use the "Bugs / Unexpected behaviors" issue template.

2. We do not answer general machine learning / computer vision questions that are not specific to
   PyTorch3D, such as how a model works or what algorithm/methods can be
   used to achieve X.

As mentioned in the "breaking changes" section of the release note, Textures has moved from pytorch3d.structures to pytorch3d.renderer. So take it out from your first import and put it in the big list in your second import. (Note: it's easier if you can share your code in text form, e.g. then I could easily demonstrate what I mean.)

here is the code that can be used in the previous version of the pytorch3d ,i use it to render the face ,but now it does not work because of the Textures has changed ,can you help me to fix it

         and you can also find the code at this place   at the line 275,the  function render_image
