How to flip a Three.js texture horizontally

Question

I'm making a 360 viewer, so textures are inside a cylinder. Problem is that they appear inverted horizontally.

I know about texture.flipY but I haven't found a texture.flipX on the source.

So how can I flip a texture horizontally, or along the x axis, directly in the code? (not using an image editor)

Answer 1

The answer was easier than I thought.

cylinder.scale.x = -1;

And don't forget to add

material.side = THREE.DoubleSide;

Answer 2

To flip a texture horizontally, you can do the following:

texture.wrapS = THREE.RepeatWrapping;
texture.repeat.x = - 1;

As mentioned in the comments, this approach requires the texture to be a power-of-two in size.
