use human it has error and use rgb_array it is no render
and self.env.render() two model also same

It seems the rendered image is pushed into the info dict.

procgen/procgen/src/vecgame.cpp

Lines 270 to 282 in 5e1dbf3

 if (render_human) { 
     struct libenv_tensortype s; 
     strcpy(s.name, "rgb"); 
     s.scalar_type = LIBENV_SCALAR_TYPE_DISCRETE; 
     s.dtype = LIBENV_DTYPE_UINT8; 
     s.shape[0] = RENDER_RES; 
     s.shape[1] = RENDER_RES; 
     s.shape[2] = 3; 
     s.ndim = 3, 
     s.low.uint8 = 0; 
     s.high.uint8 = 255; 
     info_types.push_back(s); 
 } 

So it can be accessed by env.get_info()
