Unity sees problems with sphere inside, through sphere playing panoramic video

Unity creates a sphere the default is not to see the inside of the sphere, so you need to use cull Front to modify the direction of culling, which will bring a new problem, The video being played is flipped like a mirror, so change its UV coordinates so that it flips over to float u_x=1-i.uv.x; float u_y=i.uv.y; i.uv=float2(u_x,u_y);
