Dude,

The Maya forum section is here:

Good luck!

Don't use scanline. Use either the rasterizer (might want to check out rasterize hair disposable) or raytracing (possibly with unified sampling).

Use Rasterizer.
Use hair primitives... not volume.

DON'T USE Saturation/Color/Gain variation.... all at 0.0. (Except for still images).
That's the biggest noise culprit I've found with the hair puppet shader.

It's mentioned in this tutorial. I did a test and discovered it to be true.

Note the section 2/3 of the way down:

Scene:

Possible reasons of fur flickering in animation:
1) mesh smooth node on maya fur geometry with smooth UV= ON, if so- turn it off.
2) flickering shadows- rize shadow map samples.
3) overal flichering - be sure in p_HairTK all variations (saturation, color, gain)= 0.
