Some questions on hair overlapping

Dear all,

I'm experimenting on creating a T-cell in Cinema4D (reference link), and am running into some problems with hair overlapping during the render phase.

I've created a video illustrating the problem (video link) - there are some 'blips' of light that flicker when the hairs are moving. I'm suspecting that this is due to hairs overlapping each other, and have tried reducing the number of hairs, and also increasing the hair-to-hair forces, both to no avail.

Just wondering if anyone has pointers on this problem?

Thanks for your time.

Albert

with out a file I would say what you are seeing is shading artifacts from the specular on the hair.

with such a large width on the hair the smallest move can cause a flip in the shading on the hair.

Perhaps try generating geometry for the hair rather than using the hair shader. (geo will still fold in on itself though.)
