Thanks Jeordanis,
Those tutorials were pretty useful for a basic setup. 

Is there a way to make density link to the size of feathers? In my case I have tiny feathers at the beak and they grow streadily as they move towards the back, so as the feathers get smaller I need more of them.

He Jeordanis,
I have some more testing to go ith using GenerateStrandData,
In the mean-time I noticed that the sample eagle scene has the same effect working but it doesnt have any Strand data.

From what I can see, it has custom Length and width map multiplier textures to control scale, and a texture in the distribution multiplier which does what I am looking for.
Is GenerateStrandData of any benefit?

Thanks!
ps. I'm loving Ornatrix so far! good job
