texture front and back [Solved]


I am coding a tiny 2D/3D game.
For this, I use a plane egg, which is an egg, that is just a square, without a depth.

I texture this square with a sprite. But this texture is applied only on the face of the square, not on the back.
How can I texture back too?

I guess something like squareNodePath.setTwoSided(True) can solve it
