Make animated normal map water be exponential without jumps

Hi,

I am trying to make my water shader play continuously without jumping to the first keyframe value evey time it plays through.

I have made a water shader using value nodes with noise textures as a normal map.

I set key frames at the beginning and end for the x and z values for 0 and o.5 respectively.

I set the animation to play in the puzzle, but it always jumps to the first value once played and this looks messy. I ideally want the water to play exponentially, without jumping to the first value node key setting of 0.

I see there is a way to access the value nodes via puzzle and there seems to be an option for exponential play, so I don’t have to suffer the loop jumps. However I just can’t figure out how to configure the puzzle to access the value node to play the value exponentially so I can get continuous water ripples without the jump.

Any help to guide me in setting this puzzle would be much appreciated.

Many thanks,

Jas :)
