Particle UV Flipping

Overview

Particle UV flipping provides the ability to control the UV orientation of a texture on a sprite in cascade. This allows for greater variation in appearance using the same texture and even works with sub-image textures.

Usage

Set the required Module to use Allow Image Flipping

Image flipping is controlled via XY scale, a negative value will flip the UV in either direction.

• X - Size Flip U
• Y - Size Flip V

Checking the Square Image Flipping Forces the Y flip to use the settings defined by Y in the size module, with Square screen alignment where Y normally = X size. (Y is flipped by default if you flip X)

Default Image Constant X, Constant Size (Square Alignment)

Flip Image Constant in Negative X, Constant Size (Square Alignment)

Flip Image Random X, Random Size Range X,Y (Square Alignment)

If you want a random size, and you want to randomly flip use the UniformRange Distribution. 

Flip Image Random X Random Y, Random Size Fixed X,Y (Square Alignment)

It is possible to set a constant size, and flip Axis randomly using a Uniform Distribution with Use Extremes checked.

Insert Random Initial Rotation to get more variation
