Summary

it seems to be my emitter mesh that is messing with the modifiers. I had to extract the poly and reinject them as baseobject to have it work.

I keep having bugs, or misunderstandings.

Seems like the geometry gets broken and the channels aren't read properly after some editing with vertexColor.

For checking I started over for the nth time, and just adding a length modifier that should scale the guides by a factor of 3 is making them smaller...

I simply don't get it.

ok, it is because it is assigning a channel that doesn't exist anymore... annoying.

when you start over, the modifiers aren't reseted.

now I spoted the problem, if the vertex color is pure white, the guide get scaled with a step, probably between 254 and 255. like twice as big. it is ok if if I only have greys.

actually, no. it is still jumping like there is a remap when reading the channel. Very annoying.

I just spot the error in the lisener: hair bounding box is too big...

???

Here is the scene file.

I feel like I will have to plant the feather one by one, as longer ones need more space between them than short ones. with UV layout it doesn't make a continuous filling, it is impossible to have them placed properly.

And mapping bending is also not very convienient, same problem to have continuosity.

also this problem.
