I made a grassy patch with hair particles, I then made a cloud texture to control the length of the hair. I thought it would look cool keyframing the texture brightness to make the grass grow. But then i ran into this problem where the particles flicker in and out as the texture changes. i assume its to do with how it randomly paces particles on a gradient. I have no idea how to fix this, ive tried a couple of things like contrast up the map to make more of a sharp gradient but to no luck. Any idea how i can work on this ?

Just as i post i figure it out. It was one particle instance texture that was still influencing density, If All of them influence only scale it works a treat.
